Products Description

Graphitized Petroleum Coke for Cast Steel is a premium petroleum coke product, manufactured through a specialized graphitization process. The raw material is high-quality petroleum coke. Advanced graphitization technology is employed to heat the material for an extended period under high temperatures (typically exceeding 3000°C) to transform the original amorphous carbon crystal structure into an ordered hexagonal layered structure. This ordered hexagonal layered structure is the result of the graphitization process. This process not only increases the carbon content of petroleum coke, but also significantly reduces the content of impurities such as sulfur, nitrogen, and ash. This makes graphitized petroleum coke for cast steel an excellent choice for customers seeking a high-performance product.

This product features a high carbon content and a low impurity level. The carbon content of graphitized petroleum coke for cast steel is typically in excess of 98.5%, while the concentration of impurities such as sulfur, nitrogen, and ash is exceptionally low. This characteristic makes it an ideal carburizer, effectively increasing the carbon content in castings while reducing the introduction of harmful impurities.

It has excellent absorbency properties. Graphitized petroleum coke for cast steel has excellent absorption performance in metal melts and can be quickly and evenly dissolved in molten iron or molten steel, ensuring the consistency and stability of the carburization effect.

It also provides excellent thermal insulation, which can provide a relatively stable temperature environment for the melt during the casting process, reducing heat loss and improving casting efficiency.

We offer a diverse range of particle sizes to suit your specific requirements. Our products are designed to meet the specific requirements of various casting processes. Graphitized petroleum coke for cast steel is available in a variety of particle sizes, including 0.2-1mm, 1-5mm, 4-7mm, and 5-10mm, to meet the specific requirements of different casting processes for the particle size of the carburizer.

Graphitized petroleum coke for cast steel is a highly versatile material that is widely used in the casting industry. Its main functions include:

The purpose of the carburetor is to: In the casting process, graphitized petroleum coke is used as a carburizer, which can significantly increase the carbon content in molten iron or molten steel, adjust the chemical composition of the casting, and thus improve the performance of the casting. In particular, the carburization effect of graphitized petroleum coke for cast steel is highly significant in the production of high-carbon steel, gray cast iron, and other castings.

Enhance the quality of castings: The addition of graphitized petroleum coke for cast steel can enhance the fluidity of molten iron, facilitate the floating and removal of impurities, minimize defects such as inclusions and pores in castings, and optimize the density and mechanical properties of castings. Additionally, graphitized petroleum coke for cast steel can facilitate the graphitization reaction, enhance the graphite morphology and distribution of castings, and improve the wear resistance and corrosion resistance of castings.
