Abstract
PURPOSE:To manufacture steel sheet described in the title at a very low cost, by two repetitions of cold rolling with an intermediate annealing interposed, which is combined with decarbonization, to a final sheet thickness, then by performing continuous annealing for secondary recrystallization at a limited temp. and for a limited time. CONSTITUTION:Hot rolled material for unidirectional electrical steel sheet is cold rolled two times with a combination of intermediate annealing and decarbonization interposed to a final sheet thickness. The sheet is subjected to a continuous annealing for secondary recrystallization, during which the sheet is kept at a temp. 950- 1,200 deg.C for 2-5min. Hereby manufacturing cost is remarkably reduced by omitting the decarbonizing annealing after two repetitions of conventional cold rolling.
