摘　　要：高温工业炉是电力行业中的常用设备。因为内部温度较高,内部一般都敷设耐火材料。在运行状态下,一旦炉墙体耐火材料出现破损,设备表面会很快出现超温发红现象。此时如果不能立即检修,超温区域会沿着钢壳迅速扩大,进而影响设备强度。但是因为炉内高温,修补往往需要停炉才能进行。而停炉降温就会对整个生产线造成很大的影响。文章分析并总结了一种不停炉修补炉墙的方法。Industrial furnace is a common equipment in electric power,petrochemical,metallurgy and environmental protection industries.Refractory materials are generally needed inside because of the high temperature.The equipment shell will soon over-temperature if the refractory is damaged.The over-temperature area will expand rapidly along the steel shell,which will reduce the strength of the equipment,if it cannot be repaired immediately.However,Usually,the repair work needs to stop the furnace because it is very hot in furnace.Stop furnace will have an adverse effect on the whole production line.This paper analyzes and summarizes a method of repairing furnace wall without shutdown.
