HOT SALE Graphite Petroleum Coke
In the smelting process of iron and steel products, the smelting loss of carbon elements in the molten iron is often increased due to factors such as smelting time, holding time, and overheating time, resulting in a decrease in the carbon content in the molten iron, resulting in the carbon content in the molten iron does not reach the the oretical value expected for refining. Graphitized petroleum coke is made of petroleum coke as raw material, which is placed in a graphitization furnace and made by graphitization process, and has the same performance and physical and chemical indicators as the products produced by traditional production processes.
In the smelting process, due to improper batching or charging and excessive decarburization, sometimes the carbon content in the steel does not meet the requirements of the top stage. Commonly used recarburizers are carbonized pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. In converter smelting of medium and high carbon steels, petroleum coke with few impurities is used as recarburizer. Graphitized recarburizer is a good recarburizer for smelting.
The graphitized recarburizer is the product of graphitizing petroleum coke by high temperature treatment. Graphitized petroleum coke is to place petroleum coke in a graphitization furnace, generally using Acheson furnace equipment, Acheson furnace head and tail conductive electrodes are laid with carbon material roasted products as conductive heating cores, that is, the furnace head and tail are each A carbon material calcined product is laid between a pair of corresponding conductive electrodes as a layer of conductive heating core. After a high temperature treatment of about 2600 ° C, the disordered layered carbon crystal of petroleum coke is transformed into hexagonal layered carbon, that is Petroleum coke turns into graphite, a process called graphitization. The petroleum coke processed by the graphitization process is called graphitized petroleum coke.
