三辊轧管机组使用三辊轧管机轧制无缝钢管。三辊轧管机是一种用长芯棒轧管的斜轧机。由于它是美国人阿塞尔发明的,所以通常也叫阿塞尔轧管机。阿塞尔在1932年发明三辊轧管机,1935年世界上第一台工业生产用三辊轧管机在美国的蒂姆肯滚珠轴承公司伍斯特厂投入生产。三辊轧管机是斜轧生产,它和纵轧相比可以得到精度较高的厚壁管。一般直径公差不超过±0.5％,壁厚公差为±3％。三辊轧管机的调整简单,生产效率高。只要将轧辊靠拢或放开就可以改变产品外径。管壁厚度的调整,只需选择直径适当的芯棒就可以得到解决,因此,这种轧管
Three-roller pipe rolling mill uses three-roll pipe rolling mill seamless steel pipe. Three-roll pipe mill is a kind of cross-rolling mill with long mandrel. As it was invented by American Asssel, it is often called the Assel pipe mill. Assel invented the three-roll mill in 1932 and the world’s first three-roll mill for industrial production was put into production at Timken, a Timken ball bearing company in the United States in 1935. Three-roll pipe mill is a slant mill, which can be compared with the longitudinal mill to obtain high-precision thick-walled pipe. General diameter tolerance does not exceed ± 0.5%, wall thickness tolerance of ± 3%. Three roller mill adjustment is simple, high production efficiency. As long as the roll close or release can change the product diameter. Pipe wall thickness adjustment, just select the appropriate diameter mandrel can be solved, therefore, this pipe rolling
