Abstract

PURPOSE:To lower an iron loss and to improve magnetic permeability by subjecting an electrical steel sheet having a specific compsn. to continuous annealing and rapid cooling under specific conditions, then to temper rolling. CONSTITUTION:The hot rolled sheet for the non-oriented electrical steel sheet consisting, by weight %, <=0.06% C, <=3.0% Si, 0.1-1.5% Mn, <=0.10% P, <=0.015% S, <=0.30% Al, <=0.0040% N, 0.0015-0.0040% B, and the balance Fe and inevitable impurities is cold rolled. After the cold rolled sheet is subjected to the continuous annealing, the sheet is rapidly cooled at <=40 deg.C/sec from 780-650 deg.C down to <=300 deg.C. The steel is thereafter subjected to temper rolling or an aging treatment at <=300 deg.C. The semi-processed non-oriented electrical steel sheet which is improved and stabilized in magnetic characteristics is thereby obtd.
