摘要
焊后整体热处理是球罐现场组焊施工中一道重要的工序。随着球罐的大型化发展,整体热处理施工的技术难度越来越大。文章介绍了一种新型的大型球罐整体热处理系统———欧科喷嘴DCS自动控制热处理系统,通过对该系统的原理、工艺流程和系统组成的描述,结合兰州石化公司4000m3球罐整体热处理应用实践,总结出欧科喷嘴DCS自动控制技术在大型球罐整体热处理施工中的优势,提出了改进措施,并展望了该技术的应用前景。
The whole heat treatment after welding is an important working procedure in spheral tank assembly welding in site construction. Along with the developing trend of larger spheral tanks, the technique of whole heat treatment becomes more difficult. This paper describes a new system of whole heat treatment for large spheral tank, that is Ouke nozzle DCS automatic control heat treatment system. The predominance of the technique is summarized in this paper through the description of system principle, technical flow and system composition, together with the application practice of whole heat treatment for one 4 000m3 spheral tank at Lanzhou Petrochemical Company. The improving measures are put forward and the application prospect of the technique is discussed.
