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%.
