- 摘要:
- HK-40离心浇铸炉管(我国牌号为4Cr25Ni20)已经广泛用于炼油和石化装置中,该炉管的焊接是石化工程施工中的一个难点.通过分析其焊接性能,进行焊接工艺试验,制定了合理的焊接工艺措施,在兰州炼油厂制氢装置转化炉的施工中获得了良好的焊接质量.
HK-40cent rifugal cast furnace pipe(Chinese trademark is 4Cr25Ni20)has been widely applied in oil refining and pet rochemical units,but its welding is a difficult point in petrochemical project construction.By analyzing its welding performance,and performing welding technology te-st and establishing a rationally welding technology,it acquires high welding quality in the construction of transforming furnace of hydrogen-production unit in Lanzhou Refinery.2001,1(1): 13-16 收稿日期：2000-9-6分类号：TG47参考文献：
