the role of carburizer in casting

Recarburetor is an additive for steel smelting. The use of a heater in steelmaking allows not only to reduce the use of pig iron, but also to increase the use of steel scrap. The incandescent raw material is a necessary red-hot raw material for the production of high-quality steel.

When used in a foundry, a glow can significantly increase the amount of scrap steel used, reduce the amount of pig iron used, or even eliminate cast iron. Currently, most recarburizers are suitable for smelting in electric furnaces, and a small number of recarburizers with a particularly high absorption rate are used in cupola furnaces. When smelting in an electric furnace, scrap steel and other furnace materials are fed into the recarburizer. Small doses can be added to the surface of molten iron. However, it is necessary to avoid feeding large amounts of materials into molten iron to avoid excessive oxidation, which will lead to a fuzzy decarburizing effect and insufficient carbon content in the casting. The amount of decarburizer added is determined depending on the ratio and carbon content of other raw materials. Different types of cast iron require different types of glow guns depending on the needs. The characteristics of the recarburizer itself are the choice of pure carbon-containing graphitized substances to reduce excess impurities in cast iron. The appropriate choice of recarburizer can reduce the cost of producing castings.
