凝固过程中的表面纵向裂纹是包晶钢连铸中的严重缺陷，它由合金成分和冷却速率决定。在此，为了分析钢的裂纹敏感性，提出通过包晶转变收缩确定的表面粗糙度（Ra）来评价钢的裂纹倾向。首先通过不同冷却速率下的高温激光扫描共焦实验获得了部分钢材的凝固表面粗糙度，然后通过数据分析得到了表面粗糙度的计算公式和判据。结果表明，表面粗糙度反映的包晶转变收缩和裂纹敏感性随合金成分和冷却速率的变化而显着变化。与其他方法相比，该方法成功地包含了合金成分和冷却速率对裂纹敏感性的影响。预测结果与实验观察结果之间的良好一致性表明，可以利用钢的表面粗糙度来可靠地评估钢的裂纹敏感性。
Surface longitudinal cracking during solidification is a serious defect in the continuous casting of peritectic steels, which is dictated by the alloy composition and the cooling rate. Herein, to analyze the crack susceptibility of steels, surface roughness (Ra), which is determined by the peritectic transformation contraction, is proposed to evaluate the cracking tendency of steels. First, the solidified surface roughness of some steels is obtained by a high‐temperature laser scanning confocal experiment under different cooling rates, and then the calculation formula and the criteria for surface roughness are obtained by data analysis. The results show that the peritectic transformation contraction and crack susceptibility reflected by surface roughness vary significantly with alloy compositions and cooling rates. In comparison with other methods, this method successfully contains the effect of alloy compositions and cooling rates on crack susceptibility. Good agreement between the predicted results and the experimental observations indicates that the crack susceptibility of steels can be evaluated reliably using their surface roughness.
