摘　　要：某企业的万能轧机组功能是轧制高精度钢轨的重要设备。万能轧机的轧辊系是箱型孔型,由上下水平辊和两立棍组成;在孔型的组合变化上均由液压全自动控制。在实际的轧制过程中,由于轧件的金属流动变形产生的内应力不同,进而造成上下水平辊产生严重的轴向窜动,该窜动的间隙量严重影响着轧辊系孔型的变化,进而影响着轧件的规格,严重影响产品质量。故此,该文着重探讨了轴向窜动间隙产生的原因以及如何解决间隙的问题,从而保证产品的规格质量。A universal mill is one of the most important equipment for acquiring high precision steel rail in an enterprise,upper and lower horizontal roll and two vertical roll,of whose roll system is composed,all automatic controlled by hydraulic system.A severe axial play may occur to the horizontal rollers on account of internal stress differing from metal flow and deformation in practical rolling,which leads to a critical distortion of the roll system,therefore,dimension of the rolled pieces and product quality cannot be guaranteed.This article mainly studies causes of the clearance resulting in axial movement and its solutions to ensure a better-quality product.
