摘要

简述了国内外直缝焊管机组的研究情况，并重点介绍了一种大直径双直缝不锈钢焊管连续机组的开发和应用情况。该机组采用双工位钢卷开卷装置和钢带在线自动对中及焊接装置、数控位移多角度调整的串联式柔性成形与排辊成形一体化在线成形技术、多枪复合焊接工艺和多工位焊接智能控制系统、在线自动切管及管端坡口加工一体化技术等，实现了最大外径820 mm的大直径双直缝不锈钢焊管的生产，且提高了生产效率，降低了制造成本；同时，应用了不锈钢焊管专用MES管理系统，可与该机组的控制系统有机结合，实现产品的信息化管理和智能化制造。

Abstract

Briefed here in the essay are the research status concerning the straight weld pipe mill both at home and abroad. Focused on are the development and application of a continuous mill for large-sized dual-straight seam weld pipe. This mill is equipped with the 2-station steel coil unwinding device

and the steel strip online automatic centering and welding device

the multi-step progressive cold-bend formation system

the multi-gun composite welding process and multi-station welding intelligent control system

the online automatic pipe-cutting and pipe end beveling integration technology

etc.

owing to which production of large-sized dual-straight seamless steel weld pipe with the maximum OD as 820 mm is realized with high productivity and low operation cost. Meanwhile the MES management system specialized for production of the stainless steel welded pipe is used. The system is capable of perfectly combining with the control system of the welding mill so as to realize information-based management and intelligent manufacturing of the product.
