摘要

摘要: 以某钢厂连铸板坯结晶器为原型,采取1:1水模型研究板坯连铸拉速、结晶器宽度、水口浸入深度、水口开口倾角、水口出口形状对结晶器流场及其液面波动情况的影响。结果表明:随着结晶器宽度、拉速的增加,液面波动明显增大;浸入式水口采用较大出口倾角和浸入深度以及采用椭圆形浸入式水口出口可控制结晶器液面波动以避免卷渣。研究结果为板坯连铸结晶器实际工艺参数的确定提供了参考依据。

Abstract: The effects of casting speed,width of mold,depth of submerged entry nozzle,nozzle port angle,and shape of port nozzle on the flow field and the surface flow fluctuation of the slab continuous caster from a steelmaking plant were investigated by means of a water model test with a radio of 1:1 for the purpose of providing a guidance for improving the production parameters of the slab continuous casting mold.The results showed that the surface flow fluctuation level significantly increased with increase of the width of the mold and the casting speed.Meanwhile,the surface fluctuation could be controlled by adopting a new designed nozzle with a larger outlet angel and a deeper immersion depth and an oval port,and consequently the entrainment of slag was avoided effectively.
