Steel production requires significant quantities of graphite electrodes for electrical conductivity to melt and refine molten metal. Graphite Petroleum Coke’s consistent quality with a uniform particle-size distribution and high carbon contents makes it a critical ingredient for the manufacture of graphite electrodes that provide reliable performance to steel makers worldwide. GPC is also used to manufacture friction material for brakes, clutches, and other automotive components. This allows for superior durability and performance.
The steel production application segment is the largest market for Graphite Petroleum Coke, driven by ongoing infrastructure development, construction activity, and automotive manufacturing that maintain steady global demand for raw steel products. Electric arc processes are becoming more popular due to their sustainability and recycling. This shift leads to a higher graphite electrode usage per ton of steel and a further increase in market growth.
During the refinement process, petroleum coke is converted into a highly-ordered form of carbon known as Graphitized Petroleum Coke (GPC). The Graphitization Process heats coal-derived Coke to extreme temperatures without oxygen, transforming the amorphous structure of carbon into a more crystalline one. GPC has a low content of sulfur and nitrogen, and its high fixed carbon content makes it a good material for industrial applications.
The highest quality of Graphitized Oil Coke is calcined. It is used for a wide range of applications such as graphite electrodes and carbon additives within the Iron Industry. Fuel coke, which is of lower quality, is used as a fuel in solid fuel boilers for the production of steam and to generate electricity.
Calcined carbon coke is a key ingredient in the aluminium production process. It helps produce a graphite electrode that is used during the electrolysis process of turning alumina and aluminium. It also acts as a carbon additive to improve the aluminium alloy quality, increases the reactivity of slag, reduces impurities in the molten aluminium and provides efficient energy transfer during smelting, thereby reducing overall energy consumption.
GPC’s excellent thermo conductivity increases steel smelting efficiencies, increasing productivity and reducing costs. GPC has a low ash level, which ensures impurities are removed effectively during the smelting procedure. This leads to better quality steel and more environmentally friendly production methods.
