摘    要：阐述了使用水模研究结晶器吹氩的方法,并在全比例水模型上采用15°凹底水口进行模拟,着重研究结晶器吹氩对板坯结晶器内钢/渣界面流态的影响,以及结晶器宽度、拉坯速度、水口浸入深度等工艺参数对结晶器内气泡分布的影响。

Abstract: The method of water simulation of blowing argon in slab mould was set forth in the paper,and then the influence of blowing argon in slab mould on the flow field of steel/slag interface of the mould was mainly studied,and the effects of process parameters on the distribution of argon bubble were studied too,such as the mould width,casting speed,submergence depth of SEN,etc,which are all carried out with a full-size water model and the co ncave shape SEN with the angle of 15°.
