摘　　要：钢水在结晶器内的流动状态对钢水卷渣、保护渣对夹杂物的捕捉、铸坯裂纹的形成等均有重要影响。本文利用水力学模拟的方法,研究浸入式水口形状对结晶器流场的影响,通过液面波动和流股对结晶器侧壁冲击压力的优化,选出最佳水口。Statement of liquid steel flowage in the mould seriously affects liquid steel entrapping slag, slag catching inclusions,and cracks forming on slab surface. In this paper, the effect of submerged entry nozzle shapes on flowing statement of liquid steel in the mould is studied by water model experiments. And the best of all the studied submerged entry nozzles is selected through the optimization of liquid steel surface wave and stream impacting pressure to mould side walls.
