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.

Manufacturing method for high silicon grain oriented electrical steel sheet

An apparatus and a method for rapidly heating cold-rolled strip steel (). The apparatus for rapidly heating cold-rolled strip steel () comprises a heating zone, a soaking zone, and a cooling zone, and the heating zone is sequentially divided into a first heating section (), a second heating section (), a third heating section (), and a fourth heating section () along a moving direction of the strip steel () to be heated, the first heating section () and the fourth heating section () being radiant heating sections, and the second heating section () and the third heating section () being inductive heating sections. The method for rapidly heating cold-rolled strip steel () uses the apparatus for rapidly heating cold-rolled strip steel () to heat the strip steel ().
