德士古炉镍基高温合金喷嘴的修复

Repair of Ni-based High Temperature Alloy Nozzle on Texaco Gasifier

通过对德士古炉镍基高温合金喷嘴焊接性的分析,分解了喷嘴组件在高温热震下产生的裂纹,用异种金属的焊接和合金表面的堆敷修复了德士古炉的喷嘴,同时实现了喷嘴组件的国产化。

By means of analysis on weldability of Ni-based High Temperature Alloy Nozzle on Texaco Gasifier, the crack on nozzle element generated under high temperature thermal shock is decomposed, the nozzle on Texaco gasifier is repaired by the welding process and the surface-cladding with special metal, meanwhile the components for nozzle can be domestically manufactured.
