Method for producing grain-oriented silicon steel sheet

摘要

Production of grain-oriented silicon steel sheet, in which the heating temperature of slabs is as low as that in common steels and good magnetic properties are maintained, without applying a nitriding process. The contents of Al, Se and S substantially satisfy formulae (1) and (2), and both or either of formulae (3) and (4): $$ $ $ $ Annealing\; of\; the\; hot\; rolling\; sheet\; is\; applied\; at\; a\; temperature\; of\; about\; 800\; DEG\; C\; or\; more,\; and\; about\; 1000\; DEG\; C\; or\; below;\; preferably,\; cold\; rolling\; is\; applied\; at\; about\; 100\; DEG\; C\; or\; more,\; using\; a\; tandem\; mill.\mathop{\mathrm{image}}$$$$$
