Tenova to supply Germany’s largest EAF for HKM’s transformation
Tenova will supply the electric arc furnace (EAF) for the transformation of Hüttenwerke Krupp Mannesmann (HKM) in Duisburg, Germany, into a low-emission steelmaking plant. The EAF, with its design capacity of 2.5 million tons per year, will rank as the largest in Germany and one of the largest in Europe, joining a portfolio of ultra-large EAF installations delivered by Tenova across the continents. The EAF will be equipped with Tenova's Consteel continuous scrap charging technology and the Electro Magnetic Stirring (EMS) System, developed in partnership with ABB. The new installation will become the technological heart of HKM's transition toward low-emission steel production, supporting the long-term transformation strategy of its new owner, Salzgitter.
The 2.5mtpy capacity EAF will rank as the largest in Germany and one of the largest in Europe
This investment marks the beginning of a new chapter in the history of the Duisburg-Huckingen steelworks, one of Germany's historic steel production sites. By replacing the existing blast furnace route with electric steelmaking, HKM will significantly reduce the carbon footprint of its operations while ensuring future competitiveness of the plant. As one of the most significant industrial transformation projects currently underway in the European steel industry, it demonstrates how advanced process technologies can combine with operational excellence to foster sustainable decarbonisation.
The technological package integrating Consteel and EMS claims to reduce energy consumption, minimise environmental impact and limit disturbances to the power grid, further enhancing the overall efficiency and sustainability of the steelmaking process.
Tenova's scope of supply includes a 285t Consteel EAF, complete with auxiliary plants on a turnkey basis. The furnace is designed to deliver a continuous production rate of 380t per hour to the existing secondary metallurgy line and slab caster, enabling production of high-quality flat steel products. The new facility will be installed in a dedicated building within the HKM production site.
Paolo Stagnoli, sales and marketing director EAF and LF at Tenova, said, "It took almost two years of joint studies and intensive discussions between HKM and Tenova to define this ambitious project and fine-tune the technological solution to the unique constraints and needs of the productive site. The electric arc furnace at HKM will be the most powerful and energy-efficient in Germany, and one of the most productive worldwide. This decision to adopt our technology for one of the most significant transformation projects in the European steel industry demonstrates once again that industrial competitiveness and decarbonisation can successfully go hand in hand."
