Graphitizing carbon enhancer is a product that uses calcined petroleum coke as raw material, and places the calcined petroleum coke in a graphitizing furnace, undergoes high-temperature graphitization, undergoes physical and chemical reactions, and removes sulfur and ash and other impurities.
Graphitized carbon enhancers are characterized by high fixed carbon content, usually above 98.5%, and have good electrical conductivity and high temperature resistance. Its appearance is usually black powder or particles, with uniform particle size distribution, which is conducive to rapid dissolution and absorption during steelmaking and casting. The main function of graphitized carbon enhancers is to increase the carbon content in the iron or liquid steel, thereby improving the strength and toughness of the material. It can also promote the nucleation capacity of graphite in the iron liquid, increase the ductile amount of ductile iron, improve the microstructure structure of gray cast iron, and increase the strength of gray cast iron 31.
