Abstract (en)

[origin: WO2022036382A1] The invention relates to a method for processing a silicon-containing, cold-rolled steel sheet, comprising a thermal treatment for producing a non-grain-oriented electric strip, wherein the steel sheet 2 contains between 1.5 and 6 wt.% of silicon, and wherein the steel sheet is moved in a strip-like state during the thermal treatment in a continuous process through an annealing installation having a preheating region, a hold region and a cooling region, the steel sheet being moved in the annealing installation in a vertical main conveying direction.
