| 摘 要： | 通过在全比例水模型上进行模拟,研究了结晶器宽度、拉坯速度、浸入式水口结构及水口浸入深度等工艺参数对板坯结晶器内钢/渣界面波动和界面最大流速的影响。结果表明:单独增大结晶器宽度或拉坯速度,结晶器内钢/渣界面波动和界面最大流速都将增大;而浸入式水口结构和水口浸入深度对钢/渣界面波动和界面最大流速的影响较复杂,其中,15°凸型水口通用性较好。

| Abstract: | Based on a full-size water mould,the influences of the process parameters on the flow regime of steel/slag interface of the slab mould,such as the mould width,casting speed,SEN structure、submergence depth of SEN,etc were investigated.The results show that interfacial fluctuations and the max fluid rates at slag/steel interface increases with the augment of the mould width or casting speed,while the influence of SEN structure and submergence depth of SEN on interfacial fluctuations and the max fluid rates at slag/steel interface is complicated.It is concluded that the convex type SEN with an outlet angle of 15° has better universality. |
