摘要
通过对中厚板边裂成因的研究，认为钢水精炼后N元素含量增加导致钢水浇铸过程氮化物沿晶界析出，导致700~900℃铸坯脆性增加是引起中厚板边部裂纹缺陷的主要因素，提出采用铸机边部遮蔽技术提高板坯角部在拉矫过程中的表面温度，从而解决中厚板边裂问题。
The edge of the plate fragmented into the study because of that the N element content after the refining of molten steel casting process to increase lead to nitride precipitation along the grain boundaries, resulting in 700 ~ 900 ℃ slab fra- gility leading to plate edge crack of The main factors about the use of caster slab edge technology to improve the comer shielding the pulling-straightening process surface temperature, so as to solve the problem plate edge crack.
