| 摘 要： | 板坯连铸结晶器浸入式水口吹氩使结晶器流场发生改变,引起液面波动,造成铸坯卷渣.为了的这一问题,采用大样电解方法结合扫描电镜技术,研究了板坯连铸结晶器浸入式水口不同吹氩量和吹氩分配方式对铸坯夹杂物的数量和类型的影响,提出了减少卷渣的合理结晶器吹氩量和吹氩分配方式,得出了卷渣占结晶器夹杂物的比例超过半数的结论.分析表明合理的吹氩参数对减少结晶器卷渣有着重要的意义.

| Abstract: | Argon gas injection into a slab continuous casting mold through the submerged nozzle changes the mold flow region. Surface level fluctuation in the mold would lead to slag entrapment in billets. The influence of argon injection on slag inclusion quantities and types in billets was investigated by means of SEM and bulk sample electrolysis. The reasonable technological parameters, such as the quantity and distribution of argon injection, were analyzed and provided for avoiding slag entrapment in billets. The result showed that the mass ratio of slag entrapment to the inclusions in the mold was beyond 50 % and the optimized argon gas injection was significant to reduce slag entrapment. |
