Cause of edge crack of cold rolled electrical steel and improvement measures
Because of the high brittleness of electrical steel, its edge cracking is particularly serious in the production process, which directly leads to the decline of the edge quality of the strip, and even leads to the fracture of the strip in serious cases, which greatly reduces the output of electrical steel products. Based on the situation of each grade of non-oriented electrical steel produced on site, the corresponding improvement measures are put forward.
