摘要
济钢在生产超低碳钢冷轧产品的过程中,产生大量的夹杂物缺陷造成的冷轧次、废品损失,夹杂缺陷改判率最高时达到1.5%。通过分析夹杂物的来源及形成机理,制定了相应的改进措施,减少了夹杂缺陷,超低碳钢冷轧产品夹杂的改判率降至0.6%以下。
In the production course of cold-rolling products of super low carbon steel in Jinan Steel, a large number of inclusion defects appeared, which resulted in cold-rolling sub-standard products and waste products. The largest judgment-changing rate for inclusions reached 1.5%. Through analyzing the source and forming mechanism of the inclusions, corresponding improvement measures were taken, reducing the inclusion defects. The judgment-changing rate for inclusions of cold-rolling products of super low carbon steel is decreased to 0.6% below.
