This paper introduced the tundish of magnesite coating and the prin ci ple and technique of fast-changing sizing nozzles in continuous casting process in Changgang. 介绍了连铸中间包镁质涂料和定径水口快换技术及快换的原理在长钢的应用情况和效果。
Based on the dimensionless Froude and Reynold number similarity criteria, the effect of the gas blowing on the fluid flow in the tundish is studied in a water model. 连铸中间罐内钢水的流动对于成分和温度的均匀，非金属夹杂物的去除都有重要影响。
