PRODUCT DESCRIPTION
Graphite electrode is made of high quality calcined petroleum cooke and imported needle petroleum cooke. It is manufactured through the process of calcining, dosing, mixing, forming, baking, impregnating, graphitization in a high temperature of over 3000°c, and then machining. It has the advantages of low electrical resistance, low ash content, high mechanical strength, high resistance for abrupt change of temperature and high-yield in melting process. It is widely used in Electric Arc Furnace, Ladle Furnace, Mineral-heated Furnace for steek making and other metallic or non-metallic materials, such as silicon, phosphorus, etc.
