Product Description
High Carbon Silicon，Also called silicon-carbon alloy, a ferroalloy mainly composed of Si (50%-70%) and C (10%-30%), with small amounts of S, P impurities.
- Dual functions of deoxidation + carburization: removes oxygen from molten steel and supplements C at high temp;
- Physical properties: High melting point: approximately 1680℃, High density and hardness: It is usually supplied in block or granular form., Thermal stability: not prone to deformation at high temperatures.;
- Chemical stability: usually S≤0.05%, P≤0.05%, to prevent pollution of molten steel and ensure stable deoxidation effect.
Applications
- Steelmaking industry (accounting for over 70%):
- Deoxidizer: replaces traditional deoxidizers, cuts costs and increase recovery rate .
- Alloying: Enhance the hardness, wear resistance and magnetic permeability of steel.
- Desulfurization aid: can reduce the sulfur content in steel water .
- Foundry industry: Refines cast iron grains, reduces casting cracks;
- Silicon-based alloy production: It is used as raw material to prepare silicon-manganese alloy, silicon-aluminum alloy, etc.
- Reducing agent: It is used as an auxiliary reducing agent in the smelting process of ferrochrome, ferromanganese, etc.
