摘　　要：针对锡顶吹炉炉衬寿命短、炉衬损耗区域不均衡的问题,分析了锡冶炼生产实践中炉衬的热应力变化、熔渣化学侵蚀及机械冲刷等影响因素,采取了相应措施,使顶吹炉炉衬寿命提升了14.2%,炉衬耐火材料利用率提高了14.2%,炉衬残余厚度差值由207 mm降低至59 mm。The service time of the furnace lining of the tin smelting top-blow converter is short,the loss area of the furnace lining is uneven,the following corresponding measures were taken to solve the above mentioned problems,it analyzed the thermal stress changes,slag chemical erosion and mechanical erosion of furnace lining in tin smelting production practice,the furnace lining service life of the top-blow convert is increased by 14.2%,the refractory material utilization rate of furnace lining is increased by 14.2%,the difference value of residual furnace lining thickness is decreased from 207 mm to 59 mm.
