冷铸空心轧辊是炼胶机及压延机上最重要的部件。它应具有一定的机械强度,以抵抗在辊距间工作时所产生的横压力;表面应具有抗磨性和耐蚀性以及在切割胶料与锋利钢刀接触时不致损伤的坚硬性,所以轧辊铸造技术条件要求很高。 Cold roll hollow roll rubber mixing machine and rolling machine is the most important component. It should have a certain mechanical strength to resist the horizontal pressure generated when working at roll gap. The surface should have abrasion resistance and corrosion resistance as well as the rigidity that will not be damaged when the cutting compound comes in contact with the sharp steel knife Roll casting technology demanding conditions.
