摘　　要：针对超低头板坯铸机中间包容量小、钢水在中间包内的停留时间短、钢水流场不合理、钢水中夹杂上浮去除不易、二次氧化严重等问题,通过对中间包扩容改造、增加稳流器、挡坝并进行位置优化设计,采用中间包连续测温、中间包纳米纤维绝热板及中间包碱性覆盖剂等中间包冶金技术,促进了夹杂上浮吸附,钢中全氧含量平均降低20.5×10-6,中间包平均温降减小3.3℃。In order to resolve the problems of ultra-low head slab caster like tundish small capacity, short retain time in tundish, unreasonable flow field, uneasy removing of inclusion, secondary oxidation heavy, through taking the methods like the tundish expanding capacity recon- struction, optimizing the flow field of tundish, the applying of continuous temperature measurement, nano-fihnrs insulation blank technique and the fining slag of tudish technology and so on, the aim of inclusion removing was reached. The total oxygen contain in steel was decreased by 20.5×10^-6 averagely and the average temperature drop in the tundish was reduced by 3.3℃.
