Which Is Better, Petroleum Coke Carbon Additive Or Graphite Electrode Carbon Additive

The graphitized petroleum coke carburant and graphite electrode carburant are basically the same during high temperature treatment. The difference is that the raw materials and density are different. The raw materials of graphitized petroleum coke carbon increasing agent are petroleum coke with low real specific gravity, such as sponge coke; In addition to the petroleum coke with high real proportion, some metallurgical coke is also added to the raw materials of graphite electrode to increase its hardness and density. The finished product is used as graphite electrode for graphite block or electric arc furnace. There are generally two kinds of carbon increasers for graphite electrode on the market, one is the waste and leftover materials generated in the process of machining the electrode, and the other is to crush the used graphite electrode, Screening; The graphitized petroleum coke is specially used as a casting carburizer. There are voids on the surface of the particles, which can contact molten iron in a larger area. The decomposition speed is faster, the absorption rate is higher, and the cost is relatively lower.
