Graphite carbon jacket: Graphite carbon jacket is mainly used for the furnace roll of continuous annealing furnace for cold rolled silicon steel sheet and other heating furnaces. The furnace bottom roll graphite carbon sleeve produced by our company is made of raw materials composed of calcined coke powder, binder and additional coke, which are processed through the processes of batching, kneading, molding, roasting, high-pressure impregnation, graphitization, machining and forming, chemical treatment and high-temperature treatment. The graphite carbon jacket of our company has the characteristics of large bulk density, low resistivity, small pores, uniform distribution, high strength, wear resistance, thermal shock resistance, nodulation resistance, good oxidation resistance, etc. the working temperature of the graphite carbon jacket can reach 1050 ℃, especially the reduction of iron and calcium, which greatly improves the oxidation resistance of the graphite carbon jacket, and the service life of the graphite carbon jacket can reach half a year or more.
