摘要: 针对南钢连铸板坯出现三角区裂纹的现状,通过低倍和硫印结果得出三角区裂纹的具体位置和类型,根据南钢当前的二冷配水情况,分析三角区裂纹产生的原因并提出二冷制度的改进方案。改进后三角区裂纹产生的比率下降至2.33%。

Abstract: According to the current status of triangular area cracks occurring on continuously cast slabs at Nanjing Iron & Steel Co.,LTD., the exact position and type of the triangular area crack were obtained by macroscopic structure and sulphur print test. On the basis of the model of cooling water distribution in secondary zone at Nangang, the forming reasons of triangular area crack on slab were analyzed and the corresponding improvement measures were put forward. After adopting the improvement measures, the ratio of slabs occurring triangular crack decreased to 2.33%.
