Abstract

Production method of forged silicon steel, containing more than 4% of silicon, to produce a substantially uniform diffusion of the latter by steel, characterized by operations comprising the reaction of silicon steel of a final gauge containing less than 4.0% silicon approximately, with silicon deposited on the steel, to provide an average discharge rate of silicon steel in steel in the order of 0.0075 x 10 -3 to 7.5 x 10 -3 g/cm2/minute, while the steel is at a predetermined temperature of the order of 1900 to 2300º F (1037 to 1260º C) and then the heat treatment of the reacted steel.
