Carburant is an additive applied in steelmaking.It is an essential raw material in refined steel making as well as in electrode paste production.
It is also useful for the use of Carbon extenders and other additives, such as brake pads, for friction materials. The additive belongs to the addition of steel and iron. High quality carbon additive is an indispensable additive for the production of high quality steel.
There are many kinds of additives, different production techniques, including wood carbon, coal carbon, coke, graphite, etc. There are many kinds of different kinds. The high quality carburizer generally refers to the graphitized carbon addition agent. In the high temperature condition, the carbon atoms are arranged in the microform of graphite, so it is called graphitization. Graphitization can reduce the content of impurities in the carburetor, increase the carbon content and reduce the sulfur content.
The use of carburetor in casting can greatly increase the amount of scrap steel, reduce the amount of pig iron, or use pig iron. The feeding method of furnace smelting should be put in with the waste steel and other materials, and the small dosage can be added to the surface of the molten iron. However, it is necessary to avoid large quantities of feeding in the iron water to prevent the oxidation of excessive carbon and the lack of carbon content of the casting. The amount of carbon added is determined according to the ratio of other raw materials and carbon content. Different types of cast iron are selected according to the need to choose different types of carburetor. The characteristics of the carburizer choose pure carbon graphitized material, reduce the impurities in the pig iron, and choose the suitable carbon to reduce the production cost of the casting.
