摘要
结合现场攻关实践,从连铸工艺、浇注操作和设备精度等方面对济钢厚板连铸坯角部横裂纹缺陷的形成机制进行了分析,并详细介绍了连铸坯外弧角部横裂纹的具体控制策略及取得的效果。
Combined with the site research practice, the formation mechanism of corner transverse cracks for heavy slabs was analyzed from the views of continuous casting technology, casting operations and equipment precision accuracy. In addition, the particular control strategy was put forward, and the results also were introduced for the outer arc corner transverse crack.
