混铁车内衬优化后铁水温度变化分析

Analysis of molten iron temperature changeafter optimizing inner lining of torpedo car

通过实测和数值模型计算,研究了混铁车内衬改造前后的铁水温度变化。研究结果表明:在不改变混铁车内衬厚度的情况下,优化混铁车内衬结构对铁水温度有明显影响。实测结果表明:在混铁车铁水量少、铁水初温低及运行时间长的情况下,改造后的混铁车实测铁水终温提高了17℃,铁壳表面温度降低了55℃。数值计算结果表明:在混铁车铁水量、铁水初温及运行时间与改造前混铁车实测相同的情况下,改造后混铁车铁水终温提高了24℃,铁壳表面温度降低了54℃。说明混铁车内衬改造方案保温效果显著。

Through measurement and numerical model calculation,the change of molten iron temperature before and after reconstruct of inner lining was studied.The results show that without changing the thickness of inner lining,the optimization of lining structure has obvious influence on the molten iron temperature.The measured results show that under the condition of less molten iron,low molten iron temperature and long running time,the measured final molten iron temperature is increased by 17℃and the surface temperature of torpedo car shell is decreased by 55℃after reconstruct.The numerical calculation results show that under the condition that the amount of iron,the molten iron temperature and the running time are the same as those measured before reconstruct.,the final molten iron temperature is increased by 24℃and the surface temperature of torpedo car shell is decreased by 54℃after reconstruct.It shows that the reconstruction scheme of inner lining is remarkable effect.
