What Are The Requirements For Using Carburizer in Casting

Injection molding carbureizer is a steelmaking additive that can greatly increase the amount of scrap steel used and reduce or eliminate the use of cast iron. The use of a carburetor in steelmaking can not only reduce the use of cast iron, but also increase the use of scrap steel. The carbureizer is an indispensable carburizing raw material for steel production.

Different types of cast iron require different types of carburizers. Manufacturers briefly talk about the requirements for carbureizers for steel casting.

At present, most carburizers are suitable for smelting in electric furnaces, and a small number of carburizers with a particularly high absorption rate are used in cupolas. The method of feeding into the electric furnace is that the carbureizer is placed together with the steel scrap and other materials of the furnace. Small doses can be added to the surface of molten iron.

However, it is necessary to avoid feeding a large amount of materials into the molten iron to avoid excessive oxidation, which will lead to a fuzzy carburizing effect and insufficient carbon content in the casting. The amount of carburetor added is determined by the ratio and carbon content of the other raw materials. The characteristics of the carburizer itself are the selection of pure carbon-containing graphitized substances to reduce excess impurities in cast iron. The appropriate choice of recarburizer allows you to reduce the cost of castings.
