摘要
针对济南钢铁股份有限公司冷轧板厂产品易出现黑斑缺陷问题,从原料、工艺等方面分析了黑斑缺陷成因,并提出了控制带钢板形,优化卷取张力及退火工艺、加强乳化液管理等措施,较好控制了黑斑缺陷,产品合格率达96%。
In view of easy appearing black spot defects on surface of cold rolled strip at Cold Rolling Mill of Jinan Iron Steel Co.,Ltd.,the causes were analyzed,and some countermeasures were put forward,such as controlling strip shape,optimizing coiling tension and annealing process,strengthening management of emulsion, etc.As the result,the defect could be eliminated,and the percent of pass of product reached 96%.
