摘要

通过CFX4.4商用软件对280 mm x 380 mm连铸坯结晶器内70L钢水流动传热、凝固过程进行了数值模拟，评估浸入式水口结构对结晶器综合冶金效果的影响。结果表明，随两侧孔浸入式水口插入深度和倾角的增加，坯壳厚度由宽面中心到角部逐渐减薄，但厚度比较均匀

高温区面积随之增大，位置下移;拉坯速度增加，宽面到窄面的坯壳厚度均有明显减薄

Abstract

The flow heat transfer and solidification process of 70L molten steel in a mold for 280 mm x 380 mm billet casting have been numerically simulated by a commercial software CFX4.4 to review the effect of immersed nozzle structure on comprehensive metallurgy effect. The results showed that with increasing immersed depth and obliquity of two side immersed nozzle

the thickness of cast billet shell continuously decreased from middle of wide surface to edge angle but the thickness was rather uniform

and the area of high temperature zone increased which location was moving down; and with increasing casting rate

the thickness of cast billet shell at wide and narrow surface decreased obviously
