摘要
通过对含铌、钒、钛微合金化钢连铸板坯的硫印数据进行统计分析，得出了角横裂纹的影响因素，提出了角横裂纹的控制措施，即硫含量应控制在0．004％以下，锰含量为上限，磷含量为0．007％～0．018％，过热度为10～30℃，拉速控制为1．1m／min，开发合适的二冷配水制度，提高铸机设备精度。
Through statistics and analysis on sulfur print data of continuous casting micro-alloying slab with Nb, V and Ti, the factors leading to transverse corner cracks are obtained. The control measures are proposed, that is, S, Mn and P contents should be controlled at less than 0.004 %, upper limit value and between 0.007 % and 0.018 %, respectively, overheating degree is 10～30℃, drawing speed is 1.1m/min and suitable secondary cooling water distribution schedule and high device precision of caster are alto needed.
