Graphite electrode refers to a high temperature resistant graphite conductive material (graphite electrode for short) made of petroleum coke and asphalt coke as aggregate and coal asphalt as binder through calcination, crushing and grinding powder, mixing, kneading, molding, roasting, impregnation, graphitization and mechanical processing. It is very important to choose graphite electrode suppliers, pay attention to the selection of cost-effective, do not only according to the price to choose, do not choose blindly.
When choosing a graphite electrode suppliers, always shop around for the best quality products. If you do not understand the graphite products, can be a simple inquiry to the buyers, this is also can get the first hand information, no matter what kind of product, no matter which product manufacturers, must not pay attention to just compare the price! This is a very unwise way to go, and you should know that if the quality of the graphite electrode is poor, it may not be able to meet the production needs.
In the graphite crystal structure, the coordination number of carbon atoms in the layer is 3, covalent metal bond, spacing 0.142nm, and the interlayer is connected by molecular bond, spacing 0.340nm. This special crystal structure and chemical bonding make graphite have some special technological properties.
This series of graphite products have excellent properties such as lubricity, chemical stability, high temperature resistance, electrical conductivity, special thermal conductivity and plasticity, coating and so on. Graphite electrode supplier are mostly used in electric arc furnaces, the main source of graphite electrodes. The output of electric furnace steel in China accounts for about 18% of the output of crude steel, and the graphite electrode used in steelmaking accounts for 70% ~ 80% of the total consumption of graphite electrode. Electric furnace steelmaking is the use of graphite electrode into the furnace into the current, the use of the extreme end of the arc between the furnace and the ignition of hot heat source to exercise.
We are an excellent graphite electrode suppliers, numerous advantages, graphite product variety, stable and reliable quality, welcome the majority of users to consult.
