Graphite as an electrode is made of petroleum coke, asphalt coke as particle material, coal asphalt as binder, through kneading, molding, roasting, graphitization and mechanical processing and made of a high temperature resistant graphite conductive composite material. Graphite electrode is an important high-temperature conductive material in electric furnace steelmaking, and in other electric smelting or electrolytic equipment, commonly used as conductive material. The use of graphite electrode excellent physical learning chemical properties, in other industrial management departments also have a wide range of uses, in order to produce graphite electrode main product varieties of carbon products industrial development has become an important part of our contemporary raw material industry.
The main raw materials for the production of graphite electrode petroleum coke (needle coke, including a) the production of ordinary power graphite electrode can be a small amount of asphalt coke, coal tar pitch as a binder, the characteristics of graphite electrode production are: (1) Multi-step production, long production cycle, ordinary power graphite electrode production cycle of about 45 days, the production of ultra-high power graphite electrode cycle time of more than 70 days. And the joint that needs to be impregnated several times has a longer production development cycle. (2) High energy consumption, 1t ordinary power graphite electrode needs to consume 6000kW of power. About thousands of cubic meters of gas or natural gas, metallurgical coke particles and metallurgical coke powder (secondary energy) about 1t. (3) The production of graphite electrode processes, we need many special mechanical and technical equipment and special educational structure of the kiln, the construction project investment risk is larger, investment payback period is longer.
(4) The production process of graphite electrode produces a certain amount of dust and harmful gases.Therefore, it is necessary to take measures to improve ventilation and dust environmental protection to eliminate harmful gases.
