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. 介紹了連鑄中間包鎂質塗料和定徑水口快換技術及快換的原理在長鋼的應用情況和效果。
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. 連鑄中間罐內鋼水的流動對於成分和溫度的均勻，非金屬夾雜物的去除都有重要影響。
