摘要
对高炉分厂75t铁水罐的耳轴磨损进行了分析,通过耳轴弯曲强度核算,确认需修复磨损量。通过对焊缝强度校核,证明更换耳轴的方案不可行,从而选用耳轴表面堆焊的处理工艺。焊后采用退火处理,以消除焊接残余应力,效果良好。
The paper analyzes the trunnion abrasion. The quatity of repair is determined by calculating intensity. And it is impossible to replace the trunnion by verifying intensity of welding line, then the deposit welding processing is chosed for trunnion. residual stress. Finally, the anneal is adopted after welding to relief
