连铸矩形坯角部裂纹的原因分析与防止

Analysis of cause for corner split of CC rectangle slab & it's prevention

本文通过对矩形坯产生角部裂纹时的工艺参数控制、设备运转状态和工艺操作几方面的分析,讨论了矩形坯角部裂纹形成机理,提出了控制矩形坯角部裂纹的措施。

In this paper, the mechanism of causing the corner split on continuous casting rectangle slab was discussed, and the measures to control the splits were also presented through the analysis of the technologic parameter control, the equipment operating state and the technology operation when the corner split occurred on rectangle slab.
