Essential alloying additions ensuring precise parameters and the expected strength of steel.
Ferroalloys are a key raw material in modern metallurgy and foundry. Used as charge additions to correct the chemical composition during the melting process, they determine the final microstructure, deoxidation process, and physicochemical properties of alloy steels and cast iron.
How do ferroalloys work in the production process?
Introduced into the steelmaking furnace or ladle during secondary metallurgy, these materials dissolve in the molten metal, performing key technological functions:
- Deoxidation and refining: They facilitate the effective binding and removal of oxygen from the metal bath to the slag, protecting against porosity.
- Alloying (modifying the chemical composition): The precise introduction of alloying elements allows for imparting strictly defined mechanical properties and structure to the castings.
- Ensuring stability: Carbon raisers ensure the stability of the composition of cast iron and cast steel, guaranteeing the repeatable quality and predictable parameters of every batch.
Main groups of charge materials in the PEDMO offer
We provide solutions tailored to the specific requirements of foundries and steelworks:
- Ferroalloys and alloying additions:
- Ferromanganese (FeMn).
- Ferrosilicon (FeSi).
- Metallic silicon – the basis in structure correction and deoxidation.
- Carbon raisers (Recarburizers) – a source of carbon in a highly controlled, assimilable form.
- Silicon carbide (SiC) – a reliable source of both carbon and silicon, stabilizing the melting process.
Key benefits for metallurgy and foundry
- Guarantee of obtaining the desired metal grade – precise control of the element content facilitates maintaining rigorous quality standards.
- Effective deoxidation of the molten bath – elimination of oxides and porosity, translating into the tightness of the castings.
- Increased mechanical resistance – introduced alloying elements directly affect the strength parameters and impact toughness of cast iron and steel.
