摘要
以某石化公司的超大直径厚壁Cr-Mo钢筒节的卷制为例,分析在热处理炉规格受限的条件下,如何采用二次中温卷制成型代替一次中温卷制成型的工艺技术来解决大规格筒节卷制问题,着重分析热处理工艺、二次合口工艺、吊运工装工艺、卷制参数、焊接试件性能等。
Take rolling forming of ultra-large diameter thick-wall Cr-Mo steel shell course of one petrochemical company as example,analyze the process technique which use two times intermediate temperature rolling forming to replace one-time intermediate temperature rolling forming to solve the large size shell course forming problem when heat treatment furnace size is limited.The paper mainly analyzes heat treatment process,two times forming process,lifting equipment process,forming parameter,welding test specimen property and so on.
