摘　　要：通过对马钢CSP连铸液芯压下技术改造及其实践的试验研究,分析了增加液芯压下量对铸坯形状、铸坯内部质量及其轧制工序的影响,得出了在马钢CSP连铸现有装备条件下,将液芯压下量从原设计的20mm增加到35mm是可行的,压下率达到了38.8%。该技术成功开发不仅增加了生产的灵活性,也获得了良好的冶金效果。The technological innovation and practice of liquid core reduction（LCR） of CSP caster was introduced,the effect of the amount of liquid core reduction on the slab shape,the slab internal quality and the rolling process was analyzed.Results show that the maximum amount of liquid core reduction from the original design of the 20 mm increased to 35 mm is feasible in Masteel existing equipment conditions,the reduction rate can reach 38.8%.The technology is successfully developed,not only increase production flexibility,but also get good metallurgical effects.
