Which raw materials are used for graphite electrode production?

(1) Raw material for the production of artificial graphite electrode. All low-ash raw materials such as petroleum coke and pitch coke can be used to produce high-quality graphite electrode. Adding pitch coke is to increase the strength of the product. To produce ordinary power graphite electrode, general quality petroleum coke can be used as raw material; to produce high power graphite electrode, high-quality petroleum coke and some needle coke are used; to produce ultra-high power graphite electrode, high-quality needle coke must be used as raw material , To produce high-purity graphite electrode, petroleum coke with very low ash content is required. In order to improve the lubricity and plasticity of the paste, and to improve the electrical conductivity of the product, a part of graphite crushed is also added to the graphite electrode production ingredients.

(2) Raw material for the production of natural graphite electrode. Using selected natural graphite as raw material and coal tar pitch as binder, natural graphite electrode can be produced without graphitization treatment. However, this type of electrode has high resistivity, low mechanical strength, and is easy to break during use.

(3) Raw material for production of recycled graphite electrode. Using the processing and cutting scraps or waste products of graphite materials as raw materials, after pulverization, renewable graphite electrodes can be produced without graphitization. The ash content of this type of electrode is less than 1%, the conductivity is worse than that of the artificial graphite electrode, and the resistivity is about L5 times that of the graphite electrode, but the use effect is better than that of the natural graphite electrode.
