The amount of carbon added depends on the proportion and carbon content of other raw materials. According to the different types of pig iron, different types of recarburizers can be selected according to the needs. The following briefly understands the content of the important role of the recarburizer for casting.
The use of recarburizers throughout the casting process can greatly increase the total amount of scrap, reduce the demand for scrap, and eliminate cast iron. It and waste materials should be placed in the furnace, and you can add an appropriate amount of preservative to the surface of the molten iron. However, it is necessary to prevent excessive air oxidation of a large amount of molten iron, resulting in poor results and insufficient carbon content in the casting.
Graphite core can be reasonably produced and promoted in cast carburetor. A certain proportion of cast recarburizer is added to molten iron, some are melting, some are still melting, the reagent is carbon in graphite form, and molten iron in particle form Fluidity is tangled together.
Among them, there are some large particles of cast recarburizer. After the power is turned on, the unmelted carbon will stick to the management center on the inner wall of the furnace. After the power is turned off, the unmelted carbon will be suspended. According to laboratory observations, In the whole process of graphite smelting, even if the power is cut off, the fine particles in the casting will still float in the molten iron.
Through the above introduction, I believe that everyone has a more specific understanding and understanding of the important role of recarburizer for foundry. Thank you for reading. Friends who are interested can contact us directly.
