摘　　要：为更好的优化内热式炼镁炉的冶炼工艺,根据试验炉型建立了系统模型,采用ANSYS软件,模拟了稳态下的结晶桶和给定功率下还原系统的温度场变化。结果表明:在结晶桶稳态能量输入5~6 h后,其温度梯度及分布较为稳定;在功率不变的情况下,加热5~6 h后,还原系统的温度场分布较为平稳,且有75%以上的球团料达到还原反应所需温度,此时镁的还原率和镁蒸汽的冷凝较为有利。In order to optimize the smelting process of the inner-heating magnesium smelting furnace,a system model was established on the basis of the test furnace type.The variation of temperature fields in crystallizer under the steady state and the reduction system at the given power was simulated with the ANSYS software.The results show that the temperature gradient and distribution of the crystallizer are relatively stable after the steady-state energy of the crystallizer is input for 5~6 h.With the static power,the temperature field distribution of the reduction system is relatively stable,and the pellets(above 75%)reach the required temperature for reduction reaction after heating for 5~6 h.At this stage,the reduction rate of magnesium and the condensation of magnesium steam are more favorable.
