On the basis of the Tin reverberator smelting thermodynamics process computer simulation model,the research was taken in what influences the smelting temperature,tin tenor in roasted product and reduction coal ca- pacity would do to the distribution of the main elements or components just like Pb,Zn,C,O in the grossly tin,slag and gas phase.

利用已建立的锡反射炉熔炼热力学过程计算机模型，首次研究了熔炼温度、焙砂锡品位及还原煤量对Sn、Fe、Pb、Zn、C等元素或组分分别在粗锡、炉渣及炉气相中分配行为的影响。模拟结果表明，熔炼反应最佳温度为1500K，当到达这一温度后，再提高炉温对反应过程的优化并无明显贡献，提高入炉焙砂的锡品位及还原煤量均对提高粗锡品位及锡回收率有利

The properties of soluble molybdenum oxide produced by multiple hearth furnace and reverberatory were analysed and compared.
