Needle coke and graphite electrode

Raw material is the key factor to determine the basic characteristics of carbon materials.In terms of UHP and HP graphite electrode production, high quality needle coke is the first choice, but also high quality binder asphalt, impregnating agent asphalt.But only high-quality raw materials, the lack of equipment, technology, management elements and related proprietary technology, also can not produce high-quality UHP, HP graphite electrode.

Although the industrial production of needle coke in China is later than that of foreign enterprises, it has developed rapidly in recent years and has begun to take shape. In terms of the total production volume, it can basically meet the demand of carbon enterprises at home and abroad for producing UHP and HP graphite electrodes.Foreign carbon enterprise production of large size UHP and HP graphite electrode is often preferred high-quality petroleum needle coke coke as the main raw material, the Japanese carbon enterprise also use some coal needle coke as raw material, but only for Φ 600 mm below the specifications of the graphite electrode production.At present, China’s needle coke is mainly based on coal measure needle coke. Carbon enterprises often rely on imported oil needle coke to produce high-quality UHP graphite electrodes with large specifications. In particular, the production of high-quality joint is made of imported Japanese suidao oil needle coke and British HSP oil needle coke.
