Abstract: Taking the 90 ~ 105 t hot metal ladle at steel works as prototype, a geometric similarity ratio 1： 4 water model is established in laboratory and the effect of hot metal ladle side-blowing gas for auxiliary-deslagging on skimming area is studied by physical simulation method. Results show that as blowing gas rate is 0.25 〜2.0 m³/h, with increasing gas blowing rate the deslagging area increases ； and with increasing installed angle of porous brick from 0° to 70° and installed height from 174 mm to 294 mm, the deslagging area all increases. With using single porous brick side-blowing to deslag, installed angle 70°, installed height 294 mm and gas blowing rate 0. 8 ~ 1.2 m³/h, the deslagging effect is best.

摘要： 以钢厂90～105 t铁水罐为原型,在实验室建立几何相似比1:4水模型,用物理模拟方法研究铁水罐侧吹辅助扒渣对驱渣面积的影响。结果表明,在吹气流量为0.25～2.0 m³/h时,随着吹气流量的增大驱渣面积增大。同时随着透气砖安装角度从0°到70°、安装高度从174 mm到294 mm时,驱渣面积均会增大。当用单透气砖侧吹驱渣,安装角度为70°,安装高度294 mm,流量为0.8～1.2 m³/h时,驱渣效果最好。
