Led by increasing stainless steel demands worldwide, Avesta Polarit Tornio,
now Outokumpu Stainless Tornio, decided to extend its slab production capacity from
650,000 to 1.65 million tons per year of cast products. To supply 1.0 million tons
of additional slabs, a complete new steel plant was successfully started up in
September 2002. The process route includes a 140 MVA electric arc furnace, a 150 tons AOD,
a twin ladle furnace and the world most advanced continuous casting machine.
Technological highlights together with operational results are presented.
