Schlam has teamed up with global steel giant SSAB to offer its Hercules dump truck bodies with Hardox® wear plate. The move follows Schlam being accepted into the Hardox In My Body program.

Glenn Brearey, General Manager of Schlam Payload Solutions, said the company is choosing to use Hardox steel due to its wear resistance, hardness, strength and overall performance, which surpasses the metal found in competitors dump bodies.

“Hardox has used the latest technology to create the world’s leading abrasion-resistant steel, giving our clients extended service life and high productivity in the most challenging mining environments,” Brearey said. “The Hercules is the dump body of choice for many Tier 1 miners around the globe due its lightweight and, therefore, greater payload potential. By using Hardox wear plate in the Hercules HX we’re adding another dimension to our already world-class offering.”

The Hercules HX can withstand heavy impacts without permanent deformation or cracking, ensuring more service life from the truck body investment, resulting in a lower total cost of ownership, the company said.

Every Hercules HX made by Schlam will have a ‘Hardox In My Body’ decal on it to verify it’s been manufactured using Hardox wear plate and not an inferior imitation, Schlam says.

SSAB Marketing Manager – South East Asia & Pacific – Kirs Chua said: “Each application with the sign attached has passed our strict quality control and is approved as a premium product by the SSAB board. Specialists within wear and structural technology carefully analyse each application regarding welding quality, manufacturing process and design.

“Each sign has a unique ID that is traceable and can secure the origin and material.”

Every Hercules HX is custom engineered and built from the ground up based on a mine’s unique operational requirements and is designed to deliver the same outcomes across all commodities, including coal, gold, copper and iron ore, Schlam says

BRE enlists Hardox HiAce for Super Quad iron ore transport

Equipment maintenance, Mining consumables, Mining equipment, Mining services, Steel and iron ore, , , , , , ,

Bruce Rock Engineering (BRE) says it is integrating SSAB’s new wear steel for corrosive environments such as mining in its new Hardox® HiAce.

Servicing this industry is one of BRE’s star products, the 60 m Super Quad road train with a payload up to 141 t. This vehicle is made up of four trailers pulled by a powerful truck travelling vast distances on dirt roads. Designed for heavy industry and the mining sector, a majority of these vehicles transport iron ore from the mines in the Pilbara region of Western Australia to the nearest port.

Such transportation exposes the trucks’ steel to acid corrosion caused by the environment, BRE says. This increases maintenance cost, and wear and tear.

Hardox HiAce steels are able to prolong the service life by up to three years at lower pH environments, making it cost effective and, consequently, increasing profitability, it says.

Hardox HiAce is used on the entire floor plates and the trailer sides of BRE’s new Super Quad trailers for transporting corrosive loads, with SSAB’s research and wear corrosion tests indicating a conservative estimate of a 20-30% increase in service life compared with Hardox 450.

Brenton Verhoogt, Operations Manager at Bruce Rock Engineering, said: “We did not hesitate for a minute before introducing Hardox HiAce into a Super Quad trailer combination for iron ore transport. When SSAB develops a new product, we know it has been tested thoroughly before being launched. Therefore, we are confident it will perform as Hardox 450, with the added benefit of being corrosion resistant.”

BRE’s relationship with SSAB, the manufacturer of Hardox wear plate, dates back 15 years.

LKAB plots carbon-free pathway with direct reduced iron switch

LKAB has presented its new strategy for the future, setting out a path to achieve net-zero carbon emissions from its own processes and products by 2045, while securing the company’s operations with expanded mining beyond 2060.

Jan Moström, President and CEO of LKAB, said the plan represented the biggest transformation in the company’s 130-year history, and could end up being the largest industrial investment ever made in Sweden.

“It creates unique opportunities to reduce the world’s carbon emissions and for Swedish industry to take the lead in a necessary global transformation,” he said.

The strategy sets out three main tracks for the transformation:

  • New world standard for mining;
  • Sponge iron (direct reduced iron) produced using green hydrogen will in time replace iron ore pellets, opening the way for a fossil-free iron and steel industry; and
  • Extract critical minerals from mine waste: using fossil-free technology to extract strategically important earth elements and phosphorous for mineral fertiliser from today’s mine waste.

The transformation is expected to require extensive investments in the order of SEK10-20 billion ($1.2-2.3 billion) a year over a period of around 15 to 20 years within LKAB’s operations alone. The company said the new strategy was a response to market developments in the global iron and steel industry, “which is undergoing a technology shift”.

The move could cut annual carbon dioxide emissions from the company’s customers worldwide by 35 Mt, equivalent to two thirds of Sweden’s domestic greenhouse gas emissions, it said.

Developments under the HYBRIT project, in which SSAB, LKAB and Vattenfall are collaborating on a process to enable the reduction of steel from iron ore using hydrogen instead of carbon, will be keenly observed following the miner’s announcement.

On top of this collaboration, LKAB is working with Sandvik, ABB, Combitec, Epiroc and several other industry leaders to develop the technology that will enable the transition to fossil-free, autonomous mines, it said.

Moström added: “The market for iron and steel will grow and, at the same time, the global economy is shifting towards a carbon-free future. Our carbon-free products will play an important part in the production of railways, wind farms, electric vehicles and industrial machinery.

“We will go from being part of the problem to being an important part of the solution.”

The market for steel is forecasted to grow by 50% by 2050. This growth will be achieved by an increase in the upgrading of recycled scrap in electric arc furnaces, according to LKAB. Today, the iron and steel industry accounts for more than a quarter of industrial emissions and for 7% of the world’s total carbon dioxide in the atmosphere, according to an IEA report.

The company said: “The global market price for recycled scrap is now twice that of iron ore pellets. The carbon-free sponge iron that will in time replace iron ore pellets as LKAB’s main export product is suitable for arc furnaces, allowing the company to offer industries throughout the world access to carbon-free iron.”

Moström said the switch from iron ore pellets to carbon-free sponge iron was an important step forward in the value chain, increasing the value of its products at the same time as giving customers direct access to “carbon-free iron”.

“That’s good for the climate and good for our business,” he said. “This transformation will provide us with good opportunities to more than double our turnover by 2045.”

During the transformation period, LKAB will supply iron ore pellets in parallel with developing carbon-free sponge iron.

To reach the new strategy’s goals, rapid solutions must be found for various complex issues, according to the company. These include permits, energy requirements and better conditions for research, development and innovation within primary industry.

Moström said: “Our transformation will dramatically improve Europe’s ability to achieve its climate goals. By reducing emissions primarily from our export business, we will achieve a reduction in global emissions that is equivalent to two-thirds of all Sweden’s carbon emissions. That’s three times greater than the effect of abandoning all cars in Sweden for good.

“It’s the biggest thing we in Sweden can do for the climate.”

Göran Persson, Chairman of the Board of LKAB, said: “What Swedish industry is now doing, spearheaded by LKAB, is to respond to the threatening climate crisis with innovation and technological change. In doing so, we are helping to secure a future for coming generations. This will also create new jobs in the county of Norrbotten, which will become a hub in a green industrial transformation. Succeeding in this will create ripples for generations to come. Not just here, but far beyond our borders.

“Now we are doing, what everyone says must be done.”

SSAB, LKAB and Vattenfall start up world’s first pilot plant for fossil-free steel

Environmental, Mineral processing, Power supply for mines, Steel and iron ore, Sustainable mining, , , , , , , ,

SSAB, LKAB and Vattenfall have celebrated the start-up of their HYBRIT pilot plant as part of a project to produce fossil-free sponge iron.

Sweden Prime Minister, Stefan Löfven, started up the plant together with Isabella Lövin, Minister for Environment and Climate and Deputy Prime Minister in Sweden, Martin Lindqvist, President and CEO of SSAB, Jan Moström, President and CEO of LKAB, and Magnus Hall, President and CEO of Vattenfall, today.

The achievement comes just over two years since ground was broken to mark the start of the pilot plant build for fossil-free sponge iron (direct reduced iron/hot briquetted iron) with financial support from the Swedish Energy Agency.

At the plant, HYBRIT will perform tests in several stages in the use of hydrogen in the direct reduction of iron ore. The hydrogen will be produced at the pilot plant by electrolysing water with fossil-free electricity. Tests will be carried out between 2020 and 2024, first using natural gas and then hydrogen to be able to compare production results.

The framework for HYBRIT also includes a full-scale effort to replace fossil oil with bio oil in one of LKAB’s existing pellet plants in Malmberget, Sweden, in a test period extending until 2021. Preparations are also under way to build a test hydrogen storage facility on LKAB’s land in Svartöberget in Luleå, near the pilot plant.

The HYBRIT initiative has the potential to reduce carbon dioxide emissions by 10% in Sweden and 7% in Finland, as well as contributing to cutting steel industry emissions in Europe and globally. Today, the steel industry generates 7% of total global carbon-dioxide emissions, according to the companies.

“With HYBRIT, SSAB, LKAB and Vattenfall aim to create a completely fossil-free value chain from the mine to finished steel and to introduce a completely new technology using fossil-free hydrogen instead of coal and coke to reduce the oxygen in iron ore,” they said. “This means the process will emit ordinary water instead of carbon dioxide.”

SSAB, LKAB and Vattenfall are taking another important step in their fossil-free steelmaking journey with preparations now underway for the construction of a demonstration plant on an industrial scale for its HYBRIT initiative.

The companies have also started consultations for deciding on placement of this demo plant in Norrbotten, Sweden.

The objective of the joint venture HYBRIT project is to develop the world’s first fossil-free, ore-based steelmaking process. The by-product of using fossil-free electricity and hydrogen in steelmaking, instead of coke and coal, will be water, instead of carbon dioxide. The partners believe the initiative has the potential to reduce Sweden’s total carbon dioxide emissions by 10%, hence the reason the Swedish Energy Agency has granted financial support for the project.

The plan is for construction of the demonstration plant to start in 2023, with the goal of taking the plant into operation in 2025.

“The intention is to be able to demonstrate full-scale production with a capacity of just over 1 Mt/y of iron per year, ie 20% of LKAB’s total processing capacity at Malmberget and almost half of the production capacity of SSAB’s blast furnace in Luleå,” the company said. “The goal is to be first in the world to produce fossil-free steel as early as 2026.”

HYBRIT is now starting an investigation into the selection of a location for the demonstration plant. Parallel consultations are being launched at two sites in Sweden: the Vitåfors industrial estate in Gällivare Municipality, where LKAB has mining operations, and the Svartön industrial estate in Luleå, where facilities including SSAB’s steel mill and LKAB’s ore port are located.

“The purpose is to consult and conduct an open dialogue about the location and design of the plant ahead of the upcoming selection of the site and permit application,” the companies said. “Consultation with government agencies, organisations and the public will begin in June and conclude in September 2020.”

The choice of location will have a major impact on future competitiveness and climate benefits, according to the partners, with investment decisions made once the authorisation procedure and other investigations have been completed.

HYBRIT’s pilot phase will run in parallel with the demonstration phase. In Luleå, the pilot plant for fossil-free steel will be fully constructed during the summer, and preparations are also under way to initiate construction of a temporary hydrogen store to test the technology for storing hydrogen in caverns, the partners said.

Martin Pei, Chief Technical Officer at SSAB and Chairman of HYBRIT, said: “We want to build the plant in Norrbotten. There’s good access to fossil-free electricity and competence here, as well as close collaboration with academia and the community. A demonstration plant for fossil-free iron production would also be positive for growth and jobs in the region, as well as contributing to a major climate benefit.”

Markus Petäjäniemi, Senior Vice President Market and Technology at LKAB, said HYBRIT is an important piece of the “jigsaw puzzle” in a green transition, in which we want to “climate-optimise” the whole chain from mine to finished steel by the year 2045.

“We want Norrbotten to be a world-leading arena for innovation and a centre of knowledge for the global mining and minerals sector,” he added.

Austin Engineering receives steel award plaudits for two-piece excavator bucket

Austin Engineering has placed second overall at the 2019 Swedish Steel Awards, at the same time as its two-piece excavator bucket was awarded the Peoples’ Choice Award at the event.

First awarded in 1999, the Swedish Steel Prize is an international award for companies, institutions and individuals in the steel industry. The prize, owned by SSAB, has for 20 years been recognising and rewarding those that have developed a method or product that fully utilises the potential of high-strength, wear resistant and other premium steels.

An independent professional jury assesses the entries by considering their applicability, profitability, environmental benefits, performance, innovation and creativity.

The jury said: “Austin Engineering has taken a significant leap in innovation for the design and maintenance of excavator buckets. With a modular approach, they have developed an innovative concept that combines low weight with optimal use of the complete product before scrapping. The solution utilises the characteristics of high strength and wear resistant steel and has extremely low barriers for implementation.”

Designed and manufactured in Australia by Austin Engineering, the two-piece bucket features a reusable upper section and a consumable lower segment designed for quick and safe bucket change-outs during scheduled maintenance intervals.

The reusable upper section has been designed to maintain overall structural integrity of the assembly for a predetermined service life through multiple change-outs of the lower, consumable, section.

According to the company, typical baseline service life for the upper section service will be in the vicinity of 30,000 hours; around four to five years based on industry expectations of conventional one-piece buckets of similar size and capacities.

Along with Austin Engineering, the finalists in this year’s award included Kampang from Brazil for its feeder modules for axial grain harvesters used in soybean farming, Roofit Solar from Estonia for its metal solar roofs that produce electricity and the US-based Shape Corp (overall winner) for its robust manufacturing process for 3D shaped tubes.

Steel award entries must be a method or product that fully uses the characteristics of premium steel within SSAB’s product range, but does not necessarily need to be steel produced by SSAB, according to the organisers.

HYBRIT hydrogen storage facility finds financial backing

Environmental, Metallurgy, Mining industry recognition, Power supply for mines, Steel and iron ore, Sustainable mining, , , , , , , , , , , ,

SSAB, LKAB and Vattenfall have agreed to invest SEK150 million ($15.2 million) on construction of a storage facility for hydrogen at the HYBRIT pilot plant for fossil-free steel.

The funding, which comes on top of the Swedish Energy Agency’s close to SEK50 million pledge, is an important step towards the goal of fossil-free iron and steel production, the HYBRIT joint venture partners said.

The HYBRIT initiative began in 2016. By using fossil-free electricity and hydrogen instead of coke and coal in steel production, the emissions will be water instead of carbon dioxide. The initiative has the potential to reduce Sweden’s total carbon dioxide emissions by 10%, according to company estimates.

The plan is to build the new hydrogen gas storage facility 25-35 m below the ground surface on LKAB’s land in Svartöberget, Sweden, close to the pilot plant currently under construction on SSAB’s site in Luleå. Construction of the 100 cu.m storage facility is expected to start in 2021 and it will operate from 2022-2024. It is expected to be a pressurised hydrogen gas storage facility in a bedrock cavern with a steel lining as a sealing layer.

The implementation study for the HYBRIT initiative showed large-scale storage of hydrogen gas can play an important role in Sweden’s future energy system. As well as acting as a buffer to ensure an even flow to the steel production, a large-scale hydrogen gas storage facility would offer a better opportunity to balance the electricity system with a greater proportion of weather-dependent power generation, and enable a competitive production cost for the fossil-free steel, according to the project partners.

Magnus Hall, Vattenfall’s President and CEO, said: “I am very pleased that we, as partners, are step by step developing our joint fossil-free steel project, and the support from the Swedish Energy Agency is important.

“Now, with the support of the community, we are investing in the next piece of the jigsaw puzzle for a value chain in which hydrogen gas plays a decisive role in the success of the initiative and the development of competitive fossil-free electricity generation in Sweden.”

Martin Lindqvist, SSAB’s President and CEO, said the investment in a storage facility for fossil-free hydrogen gas is “an important building block in achieving our goal of a fossil-free value chain from ore to finished steel”, with Jan Moström, LKAB’s President and CEO, adding that he was pleased the project could make use of parts of the company’s former ore port facility for the experiment.

Robert Andrén, Director General of the Swedish Energy Agency, said large, complex and expensive leaps in technology need to be taken for the sake of the climate, to achieve the goal of zero net emissions.

“Large-scale storage of hydrogen gas will be an important piece of the jigsaw puzzle for a fossil-free value chain for steel manufacturing, but also in a future electricity system with an increasing proportion of weather-dependent power,” he said.

In June last year, SSAB, LKAB and Vattenfall, the HYBRIT initiative partners, started the construction of a unique pilot plant in Luleå. Work also began recently on the reconstruction of a pellet works in Malmberget to replace fossil fuel with bio oil, with the aim of manufacturing fossil-free pellets.

The pilot plants for fossil-free steel production will be used from 2021 to 2024, and the partners are already looking into the possibility of scaling up the manufacturing by building a demonstration plant in 2025, three years earlier than previously planned, to produce fossil-free steel from iron ore for commercial use. The aim for 2035 is to sell fossil-free steel on a broad scale.

Baco mining trucks feeling the benefits of SSAB Hardox steels

The use of SSAB’s Hardox® 500 Tuf wear plate in Argentina-based Industrias Baco’s tipper truck bodies has extended the product lifespan by around 30%, according to the Nordic-based steelmaker.

Industrias Baco, the first company in Argentina to use SSAB’s specialist steel wear plate in tipper truck bodies, was so impressed by these results that 90% of its tipper bodies are now made with Hardox wear plate.

The switch to Hardox steels from traditional steel has been a fundamental part of the company’s increased sales, according to Patricia Meers, Financial Manager at Industrias Baco. “I believe Hardox steel has been a great part of our sales success. SSAB has helped us a great deal with marketing over these past years, and sales of our tippers have increased greatly with the help of Hardox wear plate. Our clients are very satisfied because the Hardox material is much more hard-wearing and versatile.”

Industrias Baco is mainly focused on producing heavy duty tippers for the mining industry.

Sales Coordinator, Nelson Bacolla, said the addition of Hardox 500 Tuf has led to the creation of new truck model with a design that helps improve the unloading process – reducing the unload time and, therefore, increasing productivity and the bottom line.

“It has been very successful,” Bacolla says. “When it comes to the distribution of the load, the truck functions much better with the new bodywork made from the new wear plate. It is the perfect combination.”

Meers witnessed first-hand the positive change that came when the company started to include Hardox material in the tipper bodies about 10 years ago. The company has also been a member of the Hardox In My Body customer program for two years.

“By having the sign on our products, it shows the customer what material we use. Nowadays customers know about Hardox wear plate and are asking for it. They know it means stronger, more lightweight and more hard-wearing tipper trucks that can carry heavier loads,” she said.

Industrias Baco uses Hardox wear plate for three different tipper truck models. They all take advantage of the same conical shape facilitated by the wear plates, accelerating the unloading process. Hardox 500 Tuf wear plate is used in its newest released tipper body model, while Hardox 450 wear plate is used in two tipper body models – one with cutaways on the side and one half-piped version. Hardox wear plate is also used in the sides and floors of the truck bodies.

HYBRIT partners to speed up fossil-free steelmaking plans

Environmental, Power supply for mines, Steel and iron ore, , , , , , , ,

The partners of the HYBRIT project, LKAB, SSAB and Vatenfall, have said they could move up their plans to build a fossil-free steelmaking demonstration plant by three years, to 2025.

Writing in Swedish daily newspaper Dagens Nyheter, the Presidents and CEOs of the three companies, Martin Lindqvist (SSAB), Jan Moström (LKAB) and Magnus Hall (Vattenfall), said they were ready to step up their work for fossil-free steel production and to move up plans to reduce carbon dioxide emissions.

The aim of HYBRIT, which is supported by the Swedish Energy Agency, is to develop a process for fossil-free steelmaking by 2035.

In 2018, the Swedish Energy Agency announced it would contribute funding amounting to more than SEK500 million ($54 million) towards the pilot-scale development of an industrial process, with three owners, LKAB, SSAB and Vattenfall, each contributing a third of the outstanding capital for the project.

Back in April, the partners said construction of a biofuel-based pelletising plant would shortly begin at LKAB’s Malmberget site, in Sweden. This “world-unique test facility”, a key component of the HYBRIT initiative, will see fossil fuels replaced with biofuel to achieve fossil-free production of iron ore pellets.

In the opinion piece in Dagens Nyheter, the company heads said: “We are ready to increase efforts from our side, but if we are to achieve success, society and lawmakers must do the same.

“We are already looking into the possibility of building a demonstration plant in 2025, three years ahead of plan, so that we can immediately thereafter produce iron ore-based, fossil-free steel for commercial use.

“The goal is to be selling fossil-free produced steel on a broad scale by 2035,” they said.

The three companies highlighted four important preconditions for this rapid transition to succeed:

  • “We need large volumes of fossil-free electricity. According to our calculations, the transition to HYBRIT requires the equivalent of about 10% of Sweden’s current electricity consumption. There will also be demand for electricity from other companies and consumers. We will need continued good access to fossil-free electricity with a high level of delivery reliability, competitive pricing and initiatives to create greater flexibility, eg through opportunities to store energy. This work must not be delayed. We are prepared to assist in these efforts;
  • “The public sector in Sweden must get involved and share the risk. Investing in groundbreaking technology such as HYBRIT is often risky, time-consuming and associated with major investments. At the same time, the projects bring great social benefit in the form of increased research, competence and opportunities to achieve climate goals. The Swedish government’s proposal to double the Industrial Evolution initiative over three years is good, but it needs to be secured for a long time to come. A fund is also needed at the EU level, and there may also be a need for support in being able to write off and scrap old plants (so-called stranded assets) in favour of new, sustainable technology;
  • “As a society, we cannot afford to keep emitting greenhouse gases. The EU trading system for emission allowances is currently being revised, and as a result, the costs of carbon dioxide emissions are rising. The system should be designed from 2020 to benefit the most climate-efficient methods from quarrying in the rock to finished steel. The system needs to be developed even after the upcoming trading period. Sweden and the rest of the EU also need to strive to change other parts of the world ahead of similar systems. Bold, sustainable solutions must not be prevented because parts of the world have a lower level of ambition and therefore carry on using old technology; and
  • “Effective, appropriate permit testing in Sweden is required so that work on the transition is not significantly delayed or stopped completely, not least so that sufficient electricity can be obtained now that we have the opportunity to move up the demonstration phase. It can sometimes take 10 years to obtain an environmental permit or a concession to lay an electrical cable or to upgrade the grid. The Swedish government is planning some measures, but more work is needed.”

The three concluded: “Steel is an amazing material. It builds communities, is hard-wearing and can in principle be recycled an infinite number of times.

“But recycled steel will not be enough. In line with social development, population growth and increasingly higher standards of living all over the world, demand will increase for new steel made from iron ore. Therefore, sustainable solutions are needed; solutions that contribute not just to solving climate change, but to social development.”

Boosting mine productivity with innovative excavator bucket design

Ian Cornfoot, Managing Director of G&G Mining, is getting ready to educate Truck & Shovel conference delegates about how innovative excavator bucket designs can increase productivity for miners.

The 100%-owned subsidiary company of SSAB has been using advanced high strength steel in the design and production of stronger, lighter and more productive excavator buckets for many years.

The company has long worked with designs to offer increased productivity to miners – with reduced weight and increased volume offering, and an increase in payload, while remaining within the machine suspended load limits.

Cornfoot’s presentation at the event – taking place at the InterContinental Singapore, September 19-20 – will address challenges and offer innovative solutions to four interrelated objectives – weight reduction, volume increase, structural life and resistance to wear – through the development and production of G&G’s XMOR High Productivity Mining Buckets. These high strength buckets use a range of advanced HARDOX steels, including HARDOX 500Tuf, which delivers exceptional wear life at a much lower weight than conventional buckets, the company says.
