本文所介绍的是棒线材轧机中所用的一架新型的三辊轧机机架(机座)。新型三辊轧机的机架内没有圆锥齿轮装置,三根轧辊轴每根都是单独驱动的。该轧机能轧制直径系列任意的或批量很小的产品,并且可以不用更换孔型或机架轧制出直径尺寸变化很小的产品。辊环消耗低,维修费用明显减少。当该轧机及机组的设计集减径和定径于一台机组,用作棒材精轧机列或线材预精轧机列时,其经济效益尤其显著。 This article describes a new three-high mill stand (stand) used in rod and wire mills. There is no bevel gear in the frame of the new three-roll mill, and each of the three roll axes is individually driven. The mill can roll any series of small diameter or a small batch of products, and can not change the hole or frame rolling diameter of small changes in products. Roll ring consumption is low, maintenance costs significantly reduced. The economic benefits are particularly significant when the design set for the mill and unit is reduced in diameter and calibrated to a single unit for use as a bar finishing train or a wire pre-finishing train.
