摘　　要：以邯钢第三炼钢厂2号板坯连铸结晶器为原型,通过水模拟实验,研究了浸入式水口底部形状、出口倾角、出口面积,以及水口插入深度等对结晶器流场的影响,确定了适宜的水口结构参数。现场生产实践表明,采用优化后的浸入式水口,能有效地改善结晶器流场,减少漏钢事故。According to the prototype of No. 2 caster mould of Handan Steel,the influence of bottom shape, outlet inclination, outlet area of submerged entry nozzle and depth of submersion on flow field were discussed by means of the water modeling study. The optimized SEN structure and operating parameters were obtained. The practice showed that these measures could effectively improved flow field in the mould and reduced breakout.
