冷轧无取向电工钢边部起皮缺陷控制方法
摘要：
本发明公开了一种冷轧无取向电工钢边部起皮缺陷控制方法，可有效消除冷轧无取向电工钢的边部起皮缺陷。该冷轧无取向电工钢边部起皮缺陷控制方法，对无取向电工钢连铸板坯长度方向的四条棱边进行倒角处理。由于将无取向电工钢连铸板坯长度方向的四条棱边进行倒角处理，从而可避免无取向电工钢轧制过程中板坯角部由于冷却较快形成的角部缺陷经轧制后在冷轧无取向电工钢边部形成起皮缺陷，大大提高了冷轧无取向电工钢产品的质量，尤其适合在冷轧无取向电工钢产品的生产作业中推广应用。
摘要（英）：

The invention discloses a control method for an edge peeling defect of cold-rolled non-oriented electrical steel, which can be used for effectively eliminating the edge peeling defect of the cold-rolled non-oriented electrical steel. The control method for the edge peeling defect of the cold-rolled non-oriented electrical steel is used for carrying out chamfering angle processing on four seamed edges in the length direction of a non-oriented electrical steel continuous casting sheet billet. Due to the chamfering angle processing on the four seamed edges in the length direction of the non-oriented electrical steel continuous casting sheet billet, the peeling defect which is formed at the edges of the cold-rolled non-oriented electrical steel after a corner defect formed by rapid cooling of slab billet corners in the rolling process of the non-oriented electrical steel is rolled can be avoided; the quality of a cold-rolled non-oriented electrical steel product is greatly improved; and the method is particularly suitable for popularization and application in the productive operation of the cold-rolled non-oriented electrical steel product.
