UMCO50 alloy produced by vacuum induction smelting, vacuum accurate casting, used for rolling plate heating furnace support block, it has good high temperature performance (1000-1300℃), good high temperature oxidation resistance and wear resistance.
Co20, Co40 and Co50 pads can effectively relieve the occurrence of laminar denudation on the top of the pad, significantly reduce the height loss of the pad and extend the effective service life of the pad, so as to improve the heating quality of the billet and significantly reduce the "black mark" temperature difference of the billet.The excellent performance of the pad comes from the more reasonable internal crystalline structure.Heating furnace CO50 slider CO50 heat resisting pad CO50 slider
