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。 The flow state of molten steel in the mold has a significant impact on the steel slag entrapment, the capture of inclusions by mold flux and the formation of slab cracks. In this paper, the influence of submerged nozzle shape on mold flow field is studied by means of hydraulic simulation. The optimal nozzle is selected through the optimization of liquid pressure and flow pressure on the sidewall of mold.
