foundry recarburizer_how much does a foundry recarburizer cost_Why should a foundry use a recarburizer?

Recarburizer are indispensable in casting, which can greatly increase the amount of scrap steel, reduce the amount of pig iron or do not use pig iron, which can greatly save costs.

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

How should casting recarburizers be used in casting?

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

How much is the recarburizer for casting?

If you want to know the specific price of the recarburizer for casting, you also need to ask the specific manufacturer. You need to know the content of your various indicators to give a specific quotation.
