摘要
通过对板坯边部纵裂纹缺陷产生的原因进行仔细调查分析,找出了其主要原因是结晶器铜板冷却水缝布置不合理造成。通过重新优化结晶器铜板冷却水缝,完善部分工艺参数后,有效地消除了铸坯边部纵裂纹缺陷。
The present paper carefully investigates and analyzes the causes to the longitudinal edge crack of slab and finds out that the primary cause is inappropriate distribution of the cooling water slits of the mould copper plates. By optimization of the cooling water slits of the mould copper plates and perfection of part of the processing parameters the longitudinal edge cracks have been effectively eliminated.
