摘要： Disclosed is a manufacturing method for a high silicon grain oriented electrical steel sheet, the silicon content of the high silicon grain oriented electrical steel is greater than 4 wt %, comprising the steps of: (1) performing decarburization annealing of a cold-rolled steel plate; (2) allowing high silicon alloy particles in a completely solid state to collide at a high speed with the surface of the decarburization annealed steel plate to be sprayed, thus forming a high silicon alloy coating on the surface of the steel plate to be sprayed; (3) coating a release agent and drying; and (4) annealing. The manufacturing method for the high silicon grain oriented electrical steel sheet of the present invention is inexpensive, and, the high silicon grain oriented electrical steel sheet produced is of stable quality and is provided with great magnetic performance.
