Hp grade graphite electrode thermal conductivity, current and price

HP (high power) graphite electrodes are used in high power electric arc furnaces (400kv.A/t).
1. Hp grade graphite electrode
The raw material of HP graphite electrode is made of high-quality petroleum coke plus needle coke, through multiple processes of calcination, impregnation and graphitization. The produced HP graphite electrodes have low resistivity, allow larger currents to pass, and have high mechanical strength, shorten the melting time of steelmaking, and improve production efficiency. Graphite electrodes are divided into three grades according to power: RP, HP, UHP. HP electrode is used for high power. Electric arc furnace (melting power is 400KV.A/t).

Hp graphite electrodes structure drawing, It is composed of body and nipple.

3. Hp grade graphite electrode thermal conductivity
Graphite electrodes have strong thermal conductivity, and graphite will become an insulator at extremely high temperatures.
