Why do foundries use recarburizer?

Carburizing agents are essential in casting, which can greatly increase the amount of scrap steel, reduce the amount of pig iron, or use no pig iron, which can greatly save costs.

Graphite Petroleum Coke

There are many types of carburizing agents, including coal-based carburizing agents, graphitized carburizing agents, petroleum coke carburizing agents, and composite material carburizing agents. Among them, graphitized carburizing agents are more practical in casting.

How should casting carburizer be used in casting?

The carburizing agent should be put into the furnace together with scrap steel and other ingredients. Small doses can be added to the surface of molten iron. However, a large amount of molten iron should be avoided to avoid excessive oxidation, resulting in an insignificant carburizing effect and insufficient carbon content in the casting. The amount of carburizing agent added should be determined based on the ratio of other raw materials and carbon content. Different types of cast iron require different types of recarburizers as needed. According to the characteristics of the carburized itself, pure carbon-containing graphitized materials are selected to reduce excessive impurities in pig iron. The selection of carburizer can reduce the production cost of castings. At the same time, pay attention to the additional time of carburizing agent for casting.

How much does a carburizer cost for casting?

If you want to know the specific price of a carburizing agent for casting, you should also ask the specific manufacturer. You need to know the content of each indicator to give a specific quotation.
