rp graphite electrode manufacturers
Which industries are graphite electrodes mainly used in?
Graphite products are still widely used in industry, and they are widely used in the following fields:
1. As a refractory material: graphite and its products have the characteristics of high temperature resistance and high strength. Graphite crucibles are mainly used in the metallurgical industry. Graphite is often used as a protective agent for steel ingots and furnace linings of steelmaking and metallurgical furnaces.
2. Conductive material: In the electrical industry, it is used to manufacture graphite electrode, carbon brush, carbon rod, carbon tube, positive electrode of mercury rectifier, graphite gasket, telephone accessories, coating of TV picture tube, etc.
3. As a wear-resistant and lubricating material, graphite is often used as a lubricant in the machinery industry. Lubricating oil cannot be used under high speed, high temperature and high pressure. Graphite wear-resistant materials can achieve high-speed sliding at 200~2000℃ without lubricating oil. Many equipments are used to transport corrosive media. rp graphite electrode manufacturers widely use graphite materials to make piston cups, sealing rings and bearings. No need to add lubricant during operation. Graphite emulsion is also a good lubricant for many metal processing (wire drawing, pipe drawing).
4. Graphite has good chemical stability. The graphite processed by rp graphite electrode manufacturers has the characteristics of corrosion resistance, good thermal conductivity and low permeability. It is widely used in heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, pumps and other equipment. It is widely used in petrochemical industry, hydrometallurgy, acid-base production, synthetic fiber, papermaking and other industrial sectors, which can save a lot of metal materials.
