Graphite electrode mainly petroleum coke, needle coke as raw material, coal asphalt binder, calcination, ingredients, kneading, molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, according to its quality index, can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode.

Graphite electrode production of the main raw material for petroleum coke, ordinary power graphite electrode can add a small amount of asphalt coke, petroleum coke and asphalt coke sulfur content can not exceed 0.5%. Needle coke is also needed to produce high - or ultra-high - power graphite electrodes. The main raw material for aluminum anode production is petroleum coke, and control sulfur content is not more than 1.5% ~ 2%, petroleum coke and asphalt coke should meet the relevant national quality standards.

Similarly, the graphite electrode fragments processed by us can also be divided into RP grade, HP grade, UHP grade, and nipple grade.

Graphite scrap (graphite scrap) refers to carbon products in graphitization after the waste and graphitization products in the processing of cutting scrap and other materials. Is used as an additive and conductive material in the steel making and casting industry graphite waste, can also be customized size processing. Graphite scrap can mainly be used as carbon additive in electric furnace steelmaking. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgy and chemical industries).

Because of its very low ash content, good electrical and thermal conductivity, graphite crushing has a wide range of uses, can be added to a variety of formulations of less ash or more ash products, graphite crushing is generally broken into small and medium-sized particles.
Adding a certain amount of graphite chips into the mixture is helpful to improve the plasticity of the paste after mixing and kneading, and to improve the yield of pressed product. Stone grinding has better adsorption ability to coal bitumen and can improve thermal conductivity and alkali corrosion resistance of carbon blocks.
