Ferrochrome (FeCr) is an essential alloy composed of chromium and iron, with chromium content typically ranging between 50% and 70%. It plays a crucial role in stainless steel production, enhancing properties like corrosion resistance, hardness, and luster.

Production Process

• Ore Selection & Preparation: High-quality chromite ore is crushed and screened.
• Smelting: The ore is reduced using coke in a submerged electric arc furnace.
• Tapping & Refining: Molten ferrochrome is tapped and refined to achieve the desired carbon content.
• Casting & Cooling: The alloy is cast into molds and solidified.

Types of Ferrochrome

• High Carbon Ferrochrome (HC FeCr): 4% - 10% carbon, commonly used in stainless steel.
• Medium Carbon Ferrochrome (MC FeCr): 1% - 4% carbon, used for specific steel grades.
• Low Carbon Ferrochrome (LC FeCr): <1% carbon, ideal for high-grade stainless steel.
• Extra Low Carbon Ferrochrome (ELC FeCr): <0.03% carbon, used in specialty steels.

Applications

• Stainless Steel: The primary use, providing corrosion resistance and durability.
• Specialty Steels: Used in aerospace, automotive, and high-performance machinery.
• Foundry & Casting: Enhances wear resistance in industrial components.

Advantages

• Corrosion Resistance: Chromium prevents rust and oxidation.
• Durability: Strengthens steel for industrial applications.
• Aesthetic Appeal: Used in consumer goods like kitchen appliances.
