Cast iron carburizing agent is a kind of additive for steelmaking, which can greatly increase the amount of scrap steel, reduce the dosage of pig iron or do not use pig iron. The use of calcined petroleum coke in steelmaking can not only reduce the use of pig iron, but also increase the utilization of scrap steel. Carburizing agent is an essential carbon addition material for producing high quality steel. Different types of cast iron are selected, and different types of carburizing agents are selected according to needs.
At present, the vast majority of recarburizer are suitable for electric furnace melting, and some of the fast absorption carburizing agents are used in cupola. The feeding way of electric furnace smelting should be carburized with the burden of steel and other materials. The small dosage can be added to the surface of molten iron. However, it is necessary to avoid bulk feeding into molten iron to prevent excessive oxidation. The amount of calcined petroleum coke is determined according to the ratio of other raw materials and carbon content. The characteristics of carburizing agent itself choose pure carbon graphitized material, reduce too much impurity in pig iron, and the selection of carburizing agent can reduce the cost of casting production.
The requirement of recarburizer for foundry steelmaking is high carbon content, high carbon content, low sulfur content, stable carburizing effect and high carbon absorption rate. It can be used in various electric furnaces to smelt cast steel and cast iron, and bring considerable economic benefits to production. But do you know what kind of carburizing agent is good carburizing agent? First, the appearance of the carburizer, clean and impurity-free.
