一种高硅晶粒取向电工钢板的制造方法
摘要：
本发明公开了一种高硅晶粒取向电工钢板的制造方法，所述高硅晶粒取向电工钢板的硅元素含量高于4wt％；包括步骤：(1)对经过冷轧的钢板进行脱碳退火；(2)使高硅合金粒子在完全固态的状态下高速碰撞经过脱碳退火的待喷涂钢板的表面，以在待喷涂钢板表面形成高硅合金涂层；(3)涂覆隔离剂并干燥；(4)退火。本发明所述的高硅晶粒取向电工钢板的制造方法成本低，制得的高硅晶粒取向电工钢板质量稳定，并且具有优异的磁性能。
摘要（英）：

The invention discloses a method for manufacturing a high silicon grain oriented electrical steel sheet. The content of a silicon element of the high silicon grain oriented electrical steel sheet is higher than 4% by weight. The method comprises the steps of (1) performing decarburization annealing on the cold rolled steel sheet; (2) enabling high silicon alloy particles to collide the surface ofthe to-be-sprayed steel sheet obtained after decarbonization annealing at high speed in a completely solid state to form a high silicon alloy coating on the surface of the to-be-sprayed steel sheet; (3) conducting coating with a release agent and drying; and (4) conducting annealing. The method for manufacturing the high silicon grain oriented electrical steel sheet is low in cost, the produced high silicon grain oriented electrical steel sheet is stable in quality, and the excellent magnetic properties are achieved.
