摘　　要：针对SPHC热轧卷板在轧制过程中出现的表面严重开裂现象,结合金相组织、扫描电镜等分析手段,对缺陷产生的成因进行了详细分析,发现锰硫比是主要影响因素,从而制定了相应的改进措施,取得了良好的应用效果。In view of severe surface cracking during rolling SPHC, Ihe causes of defects are analyzed in detail by using analytical tools microstructure, scanning electron microscnt）y. The result shows that manganese anti sulfur are the main influencing factor, thus corresponding improvement measures are developed, and good effect are achieved.
