Carburizing agents, as the name suggests, are used to increase the carbon content in molten iron. The effects of different melting processes, ingredients, electric furnaces, and metallurgical qualities in smelting will vary. So, what are the effects of carburizing agents on smelting
1. Impact on the oxidation of molten iron: During the electric furnace melting process, graphite crystal nuclei can increase during the melting process. Adding iron carbide to the cupola for melting can increase the long-term graphite nucleation of molten iron and reduce its oxidation;
2. Impact on the shrinkage of molten iron: Carburization is a more appropriate measure to reduce or prevent the shrinkage tendency of molten iron, because molten iron has the effect of graphitization expansion during solidification, good graphitization can reduce the shrinkage tendency of molten iron;
3. Impact on casting performance: Under high carbon conditions, in order to increase the strength of cast iron castings, the process of adding carburetor to all scrap steel can be used during the melting process. This not only makes the molten iron more pure, but also improves the performance of the casting material produced.
