摘要
新型轧管设备——旋压环形轧机已进入轧制试验阶段。高羽棱管、内凸筋螺旋焊管和粉末坯复合管的产品已轧制成功,电焊管的激光复合焊接技术也处于实用研究阶段。
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.
