摘　　要：针对一炉三段直接炼铅过程中控制不当可能引发泡沫渣事故的问题,对泡沫渣的形成原因以及相关影响因素进行分析,从而提出在生产过程中采取控制终渣硅酸度在1~1.5、控制合理熔池温度、稳定过渡操作、合理喷枪操作等措施,避免泡沫渣事故的发生。In three sections lead smelting process by one furnace,for the foaming slag accident caused by improper control,so we analyzed the formation reason and the relative influence factors of foaming slag,then we proposed that in the production process,the silicic acidity of the final slag shall be controlled at 1~1.5,the reasonable temperature of molten,the stable transitional operation,the reasonable spray lance operation shall be controlled in order to prevent accidents of foaming slag.
