大型设备焊后局部消应力热处理,通过力学试验与稳定性计算,分别讨论压力容器在立式与卧式状态下,热处理时高温下的组合应力,通过应力水平与材料试验温度下的许用应力进行校核,为大型设备局部热处理时,是否需要进行加固、支撑或提吊提供理论依据。 After large-scale equipment local stress relief heat treatment after welding, mechanical tests and stability calculations, respectively, to discuss the pressure vessel in the vertical and horizontal state, the combination of heat stress under high temperature, through the stress level and the material test temperature allowable stress Check for the large-scale equipment, local heat treatment, the need for reinforcement, support or lift to provide a theoretical basis.
