摘要
针对含铜低合金钢轧制钢板表面裂纹,经统计分析,通过优化关键工艺控制参数,板坯入炉温度控制小于690℃、钢水[S]含量小于0.012%,[N]含量小于0.0070%,合理控制板坯加热时间和温度,将避免含铜低合金钢轧制钢板表面裂纹,轧制钢卷表面质量良好。
The surface crack of the rolled steel plate containing copper was studied by statistical analysis. The results show that reasonable control of the slab heating time and temperature will avoid the surface crack of the rolled steel plate containing copper and low alloy steel, and the surface quality of the rolled steel coil is well. The key process control parameters are slab temperature controlled below 690?C, liquid steel [S] content less than 0.012%, liquid steel [n] content less than 0.0070%.
