一、概述热轧无缝钢管生产方式的发明和工艺的逐步完善,促进了冷拔无缝钢管生产方式的形成和发展。从十九世纪三十年代出现用链式拔机生产炉焊管至今,用冷拔法生产无缝钢管已有一百多年的历史。冷拔法可以生产其它生产形式无法得到的小直径薄壁管材,而且冷拔产品的几何尺寸、 First, an overview of the hot-rolled seamless steel pipe production methods and the gradual improvement of the technology to promote the production of cold-drawn seamless steel pipe the formation and development. From the thirties of the nineteenth century appeared with chain pulling machine production of welded pipe so far, with cold drawing production of seamless steel pipe has been a hundred years of history. Cold drawing method can produce other forms of production can not be obtained by small diameter thin-walled tubes, and cold drawn product geometry,
