PRODUCTION OF LIGHT-GAUGE STRIP OF SILICON STEEL NON- ORIENTED IN (100) FACE

摘要

PURPOSE:To produce a titled light-gauge silicon steel strip having an excellent magnetic characteristic by solidifying quickly a molten steel contg. a specific amt. of Si to a light-gauge strip and subjecting said strip to a homogenizing treatment, rolling and annealing under specific conditions. CONSTITUTION:A molten steel contg. 2.0-8.0wt% Si and consisting of the balance substantially Fe is continuously supplied from a nozzle onto a cooling body moving at a high speed, by which the molten steel is quickly solidified and cooled to a light-gauge strip. The light-gauge strip is first subjected to a homogenizing treatment in a temp. range of 700-1,100 deg.C. The thickness is adjusted by rolling to 10-300mu and thereafter the steel strip is annealed in a temp. range of 1,050-1,800 deg.C. The undesirable deterioration in the magnetic characteristic is thus stably eliminated.
