Graphite electrode refers to a kind of high-temperature resistant graphite made of petroleum coke and pitch coke as aggregates, coal asphalt as binder, after raw material calcination, crushing and grinding, batching, kneading, forming, roasting, impregnation, graphitization and machining. It is mainly used in steelmaking, as well as smelting
1. Definition and classification
Graphite electrode refers to a kind of high-temperature resistant graphite made of petroleum coke and pitch coke as aggregates, coal asphalt as binder, after raw material calcination, crushing and grinding, batching, kneading, forming, roasting, impregnation, graphitization and machining. It is mainly used in steelmaking, as well as smelting yellow phosphorus, industrial silicon, abrasive, etc. It is a conductor that releases electric energy in an arc situation to heat and melt the charge in an electric furnace. According to national standards, graphite electrodes can be divided into three types: ordinary power graphite electrodes (RP), high power graphite electrodes (HP) and ultra-high power graphite electrodes (UHP).
Classification of graphite electrodes
2. Technological process
The production process of graphite electrodes mainly includes the manufacturing of raw products (crushing, batching, kneading, forming), roasting, impregnation (primary impregnation, secondary impregnation), re-roasting, graphitization, machining and other processes, among which the main processes The roasting production cycle is longer, and the production cycle of the ordinary power graphite electrode body takes about 3 months, while the production cycle of the ultra-high power graphite electrode is as long as 5 months.
2. Industry chain analysis
1. Industrial chain
The upstream of the graphite electrode industry chain is mainly raw materials such as petroleum coke, needle coke, coal tar pitch, etc.; the middle reaches are the production and supply links of graphite electrodes, and the main products are ordinary power graphite electrodes, high power graphite electrodes and ultra-high power graphite electrodes; downstream applications in steel, yellow phosphorus, industrial silicon and other fields.
