Primetals chosen as supplier of electric arc furnace

Voestalpine has placed an order with Primetals Technologies for a 180-ton EAF Ultimate to be implemented at the Austrian steel producer’s site in Linz, Austria. Startup is scheduled for 2027.

The EAF Ultimate will be playing a key role in voestalpine’s green transition program “greentec steel.” As a first step in this ambitious decarbonization program, one electric arc furnace will be built at each of voestalpine’s sites, in Linz and Donawitz.

Primetals Technologies will supply the complete EAF Ultimate equipment, a dedusting system, a waste-heat recovery system, electrical grid stabilization, and material handling for alloying materials and additives. The order also includes full Level 1 and 2 automation, a power supply system, and the LiquiRob robotic system, which increases efficiency and occupational safety at the plant.

The EAF Ultimate will be designed to incorporate industry-leading solutions for environmentally friendly steel production. For example, the heat recovery system will convert much of the waste heat into steam, which is then fed back and used in other production units.

“We are very happy to strengthen our close and long-lasting partnership with voestalpine and to support them on their way to becoming CO2-neutral. The EAF Ultimate is part of our latest generation of electric steelmaking plants and is well-known for its raw material flexibility, fully automated operation, advanced control systems, and environmental efficiency. With this technology, voestalpine is set for a future of decarbonized steel production,” says Andreas Viehböck, Head of Upstream Technologies at Primetals Technologies.
