Calcined Petroleum Coke

Calcined petroleum coke for graphite electrodes manufacturing

Calcined Petroleum Coke

Calcined petroleum coke (CPC) is produced when raw coke is calcined. Calcination is the process of heating materials at high temperatures. In this process, remove the moisture content from the raw coke. Its appearance is a black or dark gray honeycomb structure, which belongs to the easily graphitizable carbon class. Calcined coke is obtained by calcining raw coke at 1300 .

How to make it?

When producing calcined petroleum coke, Add raw coke to the kiln tail in the rotary kiln, spray gas or heavy oil from the nozzle of the kiln head, and mix and burn with air to form a high-temperature calcination zone. The temperature of the calcination zone reaches 1200-1350 ℃.

The high temperature removes moisture and discharges volatile matter, rearranging the coke crystal structure. Then changing the carbon atom grid level, and undergoing chemical changes, resulting in a dense and conductive product. After some time, it is slowly cooled below 200 ℃, and then can be stored.

Application

It is mainly used for the prebaked anode and cathode used in electrolytic aluminum, as a carbon raiser in the metallurgical iron and steel industry, and in producing graphite electrodes and carbon products. At the same time, it is used to produce industrial silicon, yellow phosphorus, and ferroalloys. Specification:(size: 0-1mm, 1-3mm, 3-5mm, 5-8mm).

Aluminum industry: it is a critical component in producing anodes used in aluminum smelting. It provides the necessary carbon content and electrical conductivity required for efficient electrolysis.

Steel Production: it is used as a carbon additive in steel production. It helps increase the steel’s carbon content, enhancing its strength and hardness.

Foundry Industry: It is used a carbon additive for cast castings.  Improve the casting quality, reduce casting defects, and promote uniformity in the molten metal.
