Natural Graphite Block Flake Graphene Stainless Steel Road Petroleum Coke Graphite Electrode

Product Description

Natural Graphite Block Flake Graphene Stainless Steel Road Petroleum Coke Graphite Electrode
What is Graphite electrode ?
Graphite electrode refers to a kind of high-temperature graphite conductive material made of petroleum coke and asphalt coke as aggregate and coal asphalt as binder through raw material calcination, crushing and grinding, batching, mixing, molding, roasting, impregnation, graphitization and mechanical processing, called artificial graphite electrode (referred to as graphite electrode), which is different from natural graphite electrode prepared by natural graphite as raw material
Graphite electrode production characteristic
(1) Long production cycle. The production cycle of ordinary power graphite electrodes is about 45 days, the production cycle of ultra-high power graphite electrodes is more than 70 days, and the production cycle of graphite electrode joints requiring multiple impregnations is longer.
(2) High energy consumption. The production of 1t ordinary power graphite electrodes requires the consumption of about 6000kW·h of electric energy, thousands of cubic meters of gas or natural gas, and about 1t of metallurgical coke particles and metallurgical coke powder.
(3) Many production processes. The production process includes raw material calcination, crushing and grinding, batching, mixing, molding, roasting, impregnation, graphitization and machining. Its production requires many special machinery and equipment and special structure of the kiln, the construction investment is large, the investment payback period is long.
(4) A certain amount of dust and harmful gases are generated in the production process, and it is necessary to take sound ventilation dust reduction and environmental protection measures to eliminate harmful gases.
Graphite electrode Application
(1) For electric arc steelmaking furnace
(2) For mineral heating electric furnace
(3) For resistance furnaces
(4) For the preparation of special-shaped graphite products
