摘　　要：根据武汉钢铁股份有限公司炼钢总厂三分厂二流板坯连铸中间包的操作工艺参数,采用数学与物理相结合的模拟方法,对比研究了气幕挡墙技术对中间包内钢液流动特性及夹杂物去除的影响,并根据研究结果进行了工业试验。研究结果表明:采用气幕挡墙技术,可有效地改善钢液的流动状态,延长钢液的平均停留时间,降低死区体积,提高夹杂物去除率,适应超纯净钢中间包冶金的需求。According to the structure and the operating parameters of the tundish at No3 Steel-making Plant of WISCO the effect of the gas curtain technology on the flow of the liquid steel and removal rate of inclusions in the tundish was mathematically and physically simulated and thereupon industrial scale experiments carried out. Experimental results show that the flowing conditions of the liquid steel can be effectively improved, the average duration of the liquid steel in the tundish prolonged, the volume of the dead zone reduced and the removal rate of the inclusions raised by application of the the gas curtain technology. It is more suitable for the tundish in refining the super clean steel.
