一 三辊行星轧机简介 三辊行星轧机是西德Schloe-mann Siemag公司在七○年代初研制的一种新型轧机,1970～1974年进行试验,1975年投入工业使用,取得了很好的效果。这种轧机特别适合于生产合金钢的棒、管等园形产品。 这种轧机的外形和内部结构如图1,图2所示,轧机有三个锥形轧辊相互成120°安置,轧辊中心线与坯料中心线偏转一个角度。轧辊以一定的方式运动,从而在被轧制坯料上产生一个锥形的变形区,坯 A three-roll planetary mill Brief introduction Three-roll planetary mill is a new type of mill developed by Schloe-mann Siemag in West Germany in the early 1970s. It was tested from 1970 to 1974 and put into industrial use in 1975 with good results. This mill is particularly suitable for the production of alloy steel rods, tubes and other garden products. The contour and internal structure of this mill are shown in Fig. 1 and Fig. 2. The mill has three conical rolls placed at 120 ° to each other with the centerline of the roll deflected by an angle to the centerline of the blank. Roll in a certain way to move, so as to produce a tapered blank on the deformation zone, blank
