In this paper, the flow field of the approximate T-shaped tundish and the removal rate of fine inclusions are improved by changing the parameters of the flow control device of the SCB (stabilizer coupling baffle) structure. Studies have shown that the synergistic effect of the DPRW (double porous retaining wall) structure and the IRS (internal rotation stabilizer) structure has excellent performance in mixing the temperature composition of the molten steel, increasing the average residence time of the molten steel, reducing the volume fraction of the dead zone, and improving the removal rate of fine inclusions. The opening method and diameter of the double-layer retaining wall have a greater impact on the flow field parameters. The larger the diameter, the more conducive to increasing the average residence time, and the smaller the diameter, the more conducive to increasing the removal rate of fine inclusions.

多孔挡墙耦合内旋稳定器流场优化权重分析

本文通过改变SCB（稳定器耦合挡板）结构的流量控制装置的参数来改善近似T形中间包的流场和细小夹杂物的去除率。研究表明，DPRW（双层多孔挡土墙）结构与IRS（内旋稳定剂）结构的协同作用在混合钢水温度成分方面具有优异的性能，增加了钢水的平均停留时间，降低了钢水的平均停留时间。死区的体积分数，提高细小夹杂物的去除率。双层挡土墙的开孔方式和直径对流场参数影响较大。直径越大越有利于增加平均停留时间，直径越小，
