Supply high density isostatic pressing graphite plate:
1. One is to calcine anthracite with high-quality high-temperature electricity, perhaps with more graphite fragments or even all graphite fragments as aggregates,
2. The formed green products are only roasted (the roasting temperature shall not exceed 1200 ℃) and will not enter the graphitization furnace for heat treatment. This kind of carbon block is called semi graphite carbon block.
3. The other uses more easily graphitized coke as aggregate, roasts the raw products, and then enters the graphitization furnace for heat treatment at 1800 ~ 2000 ℃,
4. This kind of carbon block is called semi graphitized carbon block. The former has higher strength and hardness, while the latter has better conductivity and integrity. Graphite carbon block, with graphitized coke as raw material,
5. The graphitization treatment temperature shall reach about 2500 ℃. The difference between semi graphite carbon block and graphite carbon block lies in the degree of orderly placement of product lattice, that is, the degree of graphitization.
6. The roughness of graphitization degree can be expressed by the size of product resistivity. The lattice of graphite carbon blocks is basically completely placed in an orderly manner,
7. Resistivity less than 15 μ Ω? m; The graphitization degree of semi graphitic carbon block is low or only partially graphitized, and the resistivity is 15 ~ 45 μ Ω? m。
