Ordinary Graphite Electrode

Graphite electrode is an important conductive material in electric smelting industry, has good conductivity, thermal conductivity, high mechanical degree, high temperature oxidation resistance, good corrosion resistance, is widely used in electric arc furnace, mineral hot furnace (Production of iron alloy, pure silicon,)yellow phosphorus, matte, calcium carbide, etc.) Resistance furnace, such as the production of graphite electrode graphitization furnace, glass melting furnace, the production of silicon carbide furnace, etc. has become an important part of contemporary industrial raw materials.
The graphite electrode is divided into normal graphite electrodes, impregnated graphite electrodes, high power graphite electrode and ultra-high power graphite electrode.
