無縫鋼管生產(chǎn)技術(shù)的進(jìn)步

DEVELOPMENT OF TECHNOLOGIES FOR MANUFACTURING SEAMLESS STEEL TUBES AND PIPES

摘要: 介紹了無縫鋼管生產(chǎn)技術(shù)在穿孔、延伸、軋管、減(定)徑軋制以及工具潤(rùn)滑等方面的進(jìn)展情況。菌式穿孔機(jī)的開發(fā),使穿孔難加工管料成為可能,穿軋精度更高,并可穿軋不同外徑產(chǎn)品;延伸機(jī)主動(dòng)導(dǎo)輥及工具、潤(rùn)滑技術(shù)的開發(fā),解析、檢測(cè)、控制技術(shù)的進(jìn)步,使產(chǎn)品的品種、材質(zhì)更趨向高級(jí)化。連軋管機(jī)也逐步大型化、緊湊化。

Abstract: Introduced in the paper is the general development of manufacture technologies for seamless steel tubes and pipes concerning such aspects as piercing, elongation, pipe-rolling, reducing (sizing) and tooling lubrication etc. The advanced coned piercing mill not only makes it possible to pierce materials which were hard to be dealt with previously, but also provides a higher product accuracy and a larger product-mix as well; the development of the drive guide-roll, tooling and lubrication technique concerning the elongator and progresses in such techniques as analysis, inspection and control upgrade the varieties and materials of the products; the mandrel pipe mill has been developing toward large-sized pipe production and compact mill configuration.
