加热炉冷却水管断裂原因分析

Analysis of the Reason for the Crack on the Cooling Water Pipe of the Heating Furnace

加热炉冷却水管发生断裂,通过对其化学成分,显微组织,晶粒度,断口等进行检验分析,认为冷却水管断裂主要是因为水管局部长时间高温氧化腐蚀造成的。

A cooling water pipe of heating furnace cracked.By analyzing its chemical composition,microstructure, grain fineness,fracture and so on, it's believed that part oxidation of the high temperature for a long time and then erosion is the main reason.
