銑邊工藝在螺旋焊管生產中的應用探討

Discussion of Application of Edge-milling Process to Manufacture of Spiral Weld Pipe

摘要: 螺旋焊管生產中常用的帶鋼板邊處理方式有剪邊、刨邊和銑邊3種。銑邊工藝具有板材消耗少、成材率高,有利于提高焊接質量,有利于消除板材的月形彎缺陷,安全性好等諸多優(yōu)點,因此將成為帶鋼板邊處理的主要方式。詳細介紹了銑邊工藝的優(yōu)點,在螺旋焊管生產中應用所受影響因素以及銑邊機的工藝布置方式等。

Abstract: Three processes are commonly used for steel strip edge-trimming in manufacture of spiral weld pipes,i.e.,edge-shearing,edge-planing and edge-milling. Among these processes,edge-milling process possesses a number of advantages,such as lower strip consumption,higher yield,better welding quality,enabling easier elimination of the meniscus shaped-defect of the strip and being more safe,and therefore is expected to be the main process for steel strip edge-trimming. Elaborated in the article are the advantages of the edge-milling process,the elements that influence the application of such process in spiral weld pipe manufacture,and the process layout of the edge-milling machine.
