摘要: 新型軋管設(shè)備——旋壓環(huán)形軋機(jī)已進(jìn)入軋制試驗(yàn)階段。高羽棱管、內(nèi)凸筋螺旋焊管和粉末坯復(fù)合管的產(chǎn)品已軋制成功,電焊管的激光復(fù)合焊接技術(shù)也處于實(shí)用研究階段。Abstract: A new tube-rolling equipment——the rotary ring mill has been put into trial-rolling.Variouspipes such as high-fin pipe,spiral internal-ribbed welded pipe and powder-layer clad pipe have beensuccessfully produced with the mill.Another pipe-forming process is the combined laser technique forelectric-welded pipes which is under research for practical use.
