摘　　要：为更好地去除钢液中非金属夹杂物,在中间包内安放1个漩流室有利于夹杂物碰撞团聚上浮去除.通过水模实验对漩流中间包中夹杂物的去除作了较为详细的模拟,对影响去除率的漩流室直径、高度、入口流量、入口方向和不同的夹杂物颗粒的加入量等因素作了研究.结果表明,漩流室的引入使得夹杂物的去除率得到了提高,小粒径夹杂的上浮率最大提高了近10%,漩流中间包有利于夹杂物上浮去除.Aiming to remove the non-metallic inclusions in tundish well,a swirling chamber was set in tundish to promote inclusion floatation,collision,coalescence and removal.Water model experiment of inclusion removal in a swirling flow tundish was carried out. The variations of flotation rate of inclusions with swirling chamber diameter,height,inlet flow rate,poison,particle sizes and quantity were studied.The experimental results showed that the inclusion floation rate of swirling flow tundish was higher than that...
