摘要
以某厂宽板坯连铸结晶器为研究对象,采用1∶1水模型进行实验,研究了拉速、浸入深度、水口倾角、水口出口面积等工艺参数对结晶器内流场和液面波动的影响,以优化工艺参数,为在实际生产中减少卷渣提供依据。结果表明:随着结晶器宽度、拉速的增加,液面波动明显增大;采用较大的水口出口面积和浸入深度,可以抑制液面波动,避免卷渣。
Using the wide slab caster mold of a specific steelmaking plant as prototype, the water model with 1：1 scale is established to investigate the effects of casting speed. immersion depth, nozzle port angle, nozzle port area and other parameters on the flow field and surface flow fluctuation in the different wide slab caster mold. The processing parameters are optimized in order to reduce the slag entrainment in mold. The results show that with increase in the casting speed or width of mold, t.he surface fluctuation is prominently severe. And its proved that by adoption of deeper immersion depth and larger outlet area of the nozzle the surface fluctuation can be checked and the entrainment of slag avoided effectively.
