Graphite electrode product classification
1. Ordinary power graphite electrode锛?/strong>
It is produced using ordinary grade petroleum coke, with low graphitization temperature, high resistivity, large linear expansion coefficient, and poor thermal shock resistance, so it allows lower current density.
2. High power graphite electrode锛?/strong>
High-power graphite electrodes are produced with high-quality petroleum coke (or low-grade needle coke). Sometimes the electrode body needs to be dipped, and its physical and mechanical properties are higher than ordinary power graphite electrodes, such as low resistivity, allowing larger current density.
3. Ultra high power graphite electrode锛?/strong>
Ultra-high-power graphite electrodes must be produced using high-grade needle coke, and the graphitization heat treatment should be carried out in the internal graphitization furnace. The graphitization temperature is as high as 2800 ~ 3000 掳
C, so the resistivity is lower, allowing greater The current density and linear expansion coefficient are smaller, and it has excellent thermal shock resistance.China 350mm Graphite Electrode factory
