Types Of Recarburizers

There are many materials that can be used as recarburizers for cast iron. Commonly used are artificial graphite, calcined petroleum coke, natural graphite, coke, anthracite, and mixtures made of these materials.

1. Artificial graphite

Among the above-mentioned various recarburizers, the best quality is artificial graphite.

2. Petroleum coke

Petroleum coke is currently a widely used recarburizer.

3. Natural graphite

Natural graphite can be divided into flake graphite and microcrystalline graphite.

4. Coke and anthracite

In the process of electric arc furnace steelmaking, coke or anthracite can be added as a recarburizer during charging. Due to its high ash and volatile content, induction furnace smelting cast iron is rarely used as a recarburizer.
