Abstract
PURPOSE: To enable decarburization annealing at a higher temperature in a shorter time than in conventional methods, by plating Ni, Co, Cu or Sn at a prescribed thickness before the decarburization annealing when manufacturing a directional silicon steel plate in accordance with an ordinary method.
CONSTITUTION: Oil and fat on the surface of a silicon steel plate manufactured according to an ordinary method are removed by an aqueous solution of sodium orthosilicate or the like. At least one of Ni, Co, Cu and Sn is plated at a thickness of 0.01W5μ on the surface of the silicon steel plate in accordance with an electric, chemical or evaporation plating method or the like. The plated silicon steel plate is then annealed for decarburization, preferably at 800W950°C.
