Finish treatment method for silicon steel sheet manufactured by direct casting method

摘要

A method for manufacturing a soft magnetic steel sheet is disclosed. The silicon steel sheet is made to undergo a finish treatment so that it can be put to the practical use. The finish treatment method for an Fe-Si silicon steel sheet manufactured by a direct casting method by directly contacting a molten pool to a cooling roll according to the present invention includes the step of pickling the manufactured Fe-Si silicon steel sheet, and carrying out a cold rolling. Then the silicon steel sheet thus cold-rolled is heat-treated at a temperature above 0.5 Tm (Tm: melting temperature of the steel sheet).
