三辊联合穿轧机,是一种生产无缝管的高效能新设备。管坯在该轧机上只需一个道次的穿轧加工,就可以生产出热轧成品管来,代替了二辊自动轧管机组中的穿孔、轧管及均整三道工序。因此它不仅具有机组设备少、投资小、一次变形量大、金属变形条件好的优点,而且既节省动能和热能,又能生产各种难变形金属管,同时生产出的管子表面质量好,尺寸精度高等。 Three-roll joint wear mill, is a seamless production of high-performance new equipment. Tube blank in the mill only one pass through the rolling process, you can produce hot-rolled finished pipe to replace the two-roll automatic pipe rolling unit in the perforation, rolling pipe and the whole three processes. Therefore, it not only has the advantages of less unit equipment, small investment, large deformation, good metal deformation conditions, but also saves kinetic energy and heat energy, and can also produce various difficult-to-deform metal pipes. At the same time, the pipe has good surface quality and size High precision.
