摘　　要：结合包晶钢的凝固特点,针对其生产中出现的铸坯质量问题,进行了二冷配水制度的优化。结果表明,在二冷比水量为1.1 L/kg～1.4 L/kg,且使用适宜的二冷喷嘴和合理分配各段水量的前提下,可以避免铸坯出现质量问题,铸坯的表面质量和内部质量均良好。Combined with the solidified characteristic of peritectic steel, and according to its quality problem in pro- duction, the secondary cooling system was optimized. The results showed that under the precondition of suitable secondary cooling nozzle, reasonable secondary cooling water flux, and the water ratio in secondary cooling was 1.1L/kg - 1.4 L/kg, then the quality problem of slab could be avoided, and the internal and exterior quality of the slabs was good.
