本文介绍了300MW锅炉钢结构工程概况,分析了结构特点,制定了相应工艺措施。对原材料使用进行了严格控制,对材料的焊接性能要求作出工艺评定。对下料、制孔、组装、厚板焊接、焊后热处理、试装等制定了明确的工艺要求。对实施情况进行了总结,并提出了结论性意见。 This article introduced the 300MW boiler steel structure project overview, analyzed the structural characteristics, and formulated the corresponding technological measures. The use of raw materials is strictly controlled, and the process qualification of the material’s welding performance is required. We have established clear process requirements for blanking, hole making, assembly, thick plate welding, post-weld heat treatment, and test assembly. The implementation was summarized and concluding observations were made.
