Calcined Petroleum Coke

Calcined Petroleum Coke(CPC) is calcined by raw petroleum coke at high temperature.

Calcined Petroleum Coke (CPC) is calcined by raw petroleum coke at high temperature(12001350) and isolation air condition to eliminate the volatile matter and its performances such as thermal expansion resistance, density, conductivity, machine strength and anti-oxidation and so on are evidently improved.
Base upon experts analysis we know that Chinese oil base low sulfur and microelement contents, so that the calcined petroleum coke handled by Chinese oil has low sulfur, metals and ash contents and the total quality of the Chinese coke is much better than imports.
Calcined Petroleum Coke is used as main materials of carbon anode for Al-smelting and artificial graphite products. Except that it is also used as carburant in steel-smelting furnace, reductant of carborundum, silicon and phosphorus furnace.
