摘　　要：介绍了酒钢方坯连铸机动态二冷配水系统的改造经验。酒钢普碳钢方坯一号机经过改造以后,拉速由原来的2.4m/min提升到3m/min,但是铸坯的表面以及内部缺陷表现比较严重。对表面以及内部质量缺陷的原因进行了总结分析,重新修改了动态二冷控制模型,并对二冷配水参数进行了优化和调整,使铸坯质量明显提高。This paper mainly introduces the revamping project of dynamic secondary cooling system of the billet CCM（continuous casting machine） at JISCO.After revamping,the casting speed of No.1 billet CCM of JISCO is increased from 2.4 m/min to 3 m/min.However,the casting billets have severe internal and surface defects.After analyzing and summarizing the causes of the surface and internal defects systematically,we modify their original dynamic secondary cooling control model.At the same time,the parameters of the secondary cooling system are optimized and adjusted.Finally the billet quality is improved significantly.
