1. Raw Material Collection
Steel production starts with high-quality raw materials — iron ore, scrap metal, coal/coke, and limestone sourced and inspected for consistency.
2. Melting the Raw Material
The materials are melted in furnaces — Induction Furnace (IF), Electric Arc Furnace (EAF), or Blast Furnace (BF) — at temperatures usually above 1500 °C to produce molten iron/steel.
3. Removing Impurities (Refining)
Impurities such as sulfur and phosphorus are separated and removed as slag through fluxing and refining operations to improve metal quality.
4. Alloying — Adding Elements
Alloying elements (like carbon, manganese, chromium, nickel etc.) are added to tailor mechanical and chemical properties for different steel grades.
5. Casting the Molten Steel
Molten steel is cast into billets, ingots or slabs using continuous-casting or ingot-casting techniques as starting shapes for downstream processing.
6. Rolling & Shaping
Billets or slabs are hot-rolled and finished into TMT bars, rounds, flats, channels, and angles through rolling mills and finishing lines.
7. Cooling & Quality Testing
Finished products are cooled, straightened, cut, and subjected to mechanical and chemical tests (strength, ductility, chemical composition) before dispatch.
Conclusion: The process of steel manufacturing combines melting, purification, alloying, casting, rolling and rigorous testing to produce strong, durable, and reliable steel — exactly what Dhan Luxmi Steels delivers.
