DESCRIPTION:
The graphite electrode is mainly made of petroleum coke and needle coke as raw materials and coal and bitumen as the binding agent , through the process of calcining, batching, mixing, pressure molding, roasting, graphitization and machining.
Production Flow Chart:

Production process: the cost of petroleum coke, needle coke, coal pitch and other raw materials accounts for 66.88%. The production cycle is over 50 days, and the ultra-high power is up to 65 days.
Raw materials and costs: petroleum coke, needle coke and coal tar pitch and other raw materials account for 66.88% of the graphite electrode cost.
Raw material: low sulfur petroleum coke, coal measure needle coke as the aggregate, coal pitch as the binder.
Graphite electrode from petroleum coke, needle coke as raw materials, coal tar pitch as binder, through the raw material crushing, mixing, molding, roasting, impregnation, secondary roasting, graphitization, machining, quality inspection, packaging factory and other 11 processes prepared.
Petroleum coke: Petroleum coke is a petroleum product obtained by distillation of crude oil to separate light and heavy oil, and then hot cracking of heavy oil. Petroleum COKE black porous, carbon content of more than 80%, ash content is generally less than 0.5%, in the chemical industry, metallurgy and other industries have a wide range of uses, is the production of artificial graphite products and electrolytic aluminum carbon.
products for the main raw materials. Petroleum coke can be divided into high sulfur coke (containing sulfur more than 1.5%), sulfur coke (containing sulfur 0.5% ~ 1.5%), and low sulfur coke (containing sulfur less than 0.5%) three kinds, graphite electrode and other artificial graphite products generally use low sulfur coke production.
Needle coke: Needle coke is a kind of high quality coke with obvious fiber texture, especially low coefficient of thermal expansion and easy graphitization. The physical properties of needle coke are very obvious anisotropy, parallel to the particle long axis direction has good electrical and thermal conductivity and low thermal expansion coefficient, so needle coke is the key raw material for manufacturing high power or ultra-high power graphite electrode, the graphite electrode made of low resistivity, small thermal expansion coefficient, good thermal shock resistance. According to the source of raw materials, needle coke can be divided into two kinds: oil based needle coke produced from petroleum residue and coal based needle coke produced from refined coal bitumen.
Coal tar pitch: coal tar is one of the main products of deep processing. for a variety of hydrocarbons mixtures, composition is more complex, at room temperature for black high viscosity semi-solid or solid. According to the softening point, the coal pitch can be divided into three kinds: low temperature, medium temperature and high temperature coal pitch. Coal tar pitch is used as a binder and impregnating agent in the production of graphite electrode. Generally, medium temperature or medium temperature modified coal tar pitch with moderate softening point and high coking value is used.
