METHOD FOR PRODUCING GRAIN-ORIENTED ELECTROMAGNETIC STEEL PLATE

摘要

In the disclosed method, a silicon steel material is heated (step S1) in a predetermined temperature range in response to the quantity of contained B, N, Mn, S, and Se, and then hot rolling (step S2) is performed. Furthermore, the end temperature (Tf) of the finish rolling of the hot rolling is performed in a predetermined temperature range in response to the quantity of contained B. Through this treatment, a predetermined quantity of BN is compound-deposited with MnS and/or MnSe.
