Graphite products are still widely used in industry and are widely used in the following fields:
1.As refractory material: graphite and its products have the characteristics of high temperature resistance and high strength.Graphite crucible is mainly used in metallurgical industry.Graphite is commonly used as a protective agent for ingot and lining of metallurgical furnace for steelmaking.
2.Conductive materials: in the electrical industry, used to manufacture graphite electrode, carbon brush, carbon rod, carbon tube, mercury rectifier anode, graphite gasket, telephone accessories, television picture tube coating, etc.
3.Graphite as wear-resisting and lubricating materials, often used as a lubricant in the machinery industry.Lubricating oil can not be used under high speed, high temperature and high pressure.Graphite wear-resistant material at 200~2000℃ without lubricating oil can achieve high-speed sliding.Many devices are used to deliver corrosive media, and graphite electrode manufacturers use the material extensively for piston cups, seals and bearings.No lubricant is required during operation.Graphite emulsion is also a good lubricant for many metal processing (wire drawing, tube drawing).
4.Graphite has good chemical stability.The specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability.Widely used in heat exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter, pump and other equipment.Widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.
