Graphite Electrodes RP Definition
Graphite electrode RP refers to petroleum coke, asphalt coke as aggregate, coal asphalt as binder, through raw refractory material calcination, crushing milling, compounding, kneading, forming, roasting, impregnating, graphitization and mechanical processing. High temperature graphite conductive refractory material, called artificial graphite electrode (abbreviated as graphite electrode). Graphite electrode RP is distinguished from natural graphite electrode prepared by using natural graphite as raw refractory material.

Graphite Electrode RP Advantage
1.HP grade graphite electrodes are easier to process and process faster than copper electrodes
2.HP graphite electrode advantage is that it is easy to process, the discharge processing rate is high, and the graphite loss is small.
Graphite Electrode RP Production Characteristics
1.Graphite electrode RP production cycle is long.
2.Graphite electrode RP have high energy consumption.
3.Graphite electrode RP are many production processes.
4.Harmful gases and dusts are generated during the production of RP graphite electrode process, and environmental protection is required.
5. Production of carbonaceous raw refractory materials required petroleum coke and coal tar pitch are the production and processing by-products of refining enterprises and coal chemical enterprises. The quality and stability of raw refractory materials are difficult to be fully protected.
