Abstract

PURPOSE:To produce the titled steel sheet of superior magnetic characteristics by subjecting a low-carbon steel slab added with Si and Al to hot rolling including dissimilar peripheral speed rolling then to high-temperature coiling and holding the same at high temp. thence cold rolling and annealing the same. CONSTITUTION:A steel slab contg. <=0.05% C, 2.4-4.5.% Si, <=1.0% Al is subjected to at least one pass of dissimilar peripheral speed rolling of varied peripheral speeds between upper and lower work rolls and the hot rolled steel strip coil having been coiled at high temp. after the end of hot rolling is held at temp. >=750 deg.C for >=10min. Thence, it undergoes respective processes of cold rolling and annealing, whereby the nondirectional electrical steel sheet is produced. According to this method, the nondirectional electrical steel sheet having superior magnetic characteristics, above all, much lower watt loss value is obtained.
