Graphitized Petroleum Coke Blocks

Graphitized petroleum coke blocks

Graphitized petroleum coke blocks (GPC blocks) are large-sized carbon blocks that are manufactured from high-quality petroleum coke by a high-temperature graphitization process. The graphitization process refers to heating the petroleum coke to very high temperatures (more than 2500°C) in a controlled surroundings to transformed it into a highly crystalline form of carbon with a high degree of graphitization.

GPC blocks looks black or dark grey and with a high carbon content (normally over 98%) and a low ash content. They have a dense and uniform structure, with a high degree of mechanical strength and nice thermal and electrical conductivity.

Steel making: GPC blocks are used as a carbon additive when produce steel. They are put into steel making process to improve carbon content, which increase steel’s hardness and strength.

Foundry casting: GPC blocks are used as a carbon additive when produce cast iron and other metal castings. They help to decrease the quantity of scrap metal needed and enhance the quality of the castings.

Carbon products: GPC blocks are used as a raw material when produce electrodes for electric arc furnaces and other carbon-based goods.

Chemical industry: GPC blocks are used as a raw material when produce various chemical compounds, for instance, carbon black and graphite electrodes.
