Description

High Sulfur Graphite, commonly known as CPC (Calcined Petroleum Coke), is one of the important and widely used materials extensively applied in various steel and cast iron foundry industries. This material typically appears black or dark gray in color, with a granular and porous texture, and a particle size of 1–5 mm.

The most important and common applications of high sulfur graphite:

• Used as an additive in the production of alloy steels and gray cast iron components to increase carbon content and enhance graphite formation in the structure (the formed graphite acts as a reinforcement, improving crack resistance).
• Increases strength and hardness.
• Used in the production of gray cast iron.
• Applied in the manufacturing of casting molds and coatings due to its lubricating properties and heat resistance.
• Used in the production of carbon electrodes for electric arc furnaces.
• Removal of molten impurities and desulfurization due to the presence of high sulfur content in it
• Improves molten metal fluidity, ultimately reducing shrinkage and porosity in cast parts.
