Carbographtie is China’s leading supplier with more 20 years of expertise in carbon and graphite industry.Founded in 1992 in east-central China, It mainly produce graphite electrode and electrode paste. Our company own rich expertise in operating bulk order 200tons, 300 tons 500tons. Annual output is 50000 tons of RP HP UHP graphite electrode and 200000 tons of carbon electrode paste.
The graphite electrode is in electrically calcined anthracite, petroleum coke, graphite scrap, coal tar as main raw materials, carbon conductive material mixing, molding, sintering, mechanical processing, it is since twenty-first Century in a new energy saving and environmental protection materials in China gradually promote the use of, as the furnace with conductive electrode widely used in industrial silicon, iron alloy, calcium carbide, phosphorus and other metal or non metal smelting process. Carbon electrode is an energy saving and environmental friendly product. It can greatly reduce power consumption and reduce pollution in the use of calcium carbide and ferroalloy ore heating furnaces. It is the replacement product of electrode paste.
1)Good electrical conductivity
2)High resistance to thermal shock
3)High mechanical strength
1) used for electric arc furnace
2)used for ore heat furnaceItems | Unit | Graphite electrode | ||||
