Manufacturing Process

The production of Kamdhenu TMT Bars involves a sophisticated multi-step process, combining traditional steelmaking with cutting-edge technology:

1. Raw Material Selection: High-quality iron ore (Fe content >62%) and scrap steel are carefully chosen to ensure the final product's integrity. Kamdhenu sources its raw materials from reputable suppliers, with each batch undergoing stringent quality checks.
2. Ironmaking: The raw materials are melted in blast furnaces at temperatures exceeding 1,500°C. This process, known as smelting, reduces iron oxides to liquid iron. Kamdhenu's blast furnaces are equipped with pulverized coal injection (PCI) technology, improving energy efficiency by up to 30%.
3. Steel Billet Production: The molten iron is refined in basic oxygen furnaces where impurities are removed, and alloying elements are added to achieve the desired steel composition. The liquid steel is then cast into billets using continuous casting technology, which ensures uniform quality and reduces energy consumption by 20% compared to traditional ingot casting.
4. Hot Rolling: Billets are heated to around 1,200°C in reheating furnaces and passed through a series of rolling stands to achieve the desired shape and size. Kamdhenu's hot rolling mill is equipped with automatic gauge control (AGC) systems, ensuring dimensional accuracy within ±0.1mm.
5. Quenching: The hot bars, at approximately 900°C, are rapidly cooled using a specialized water-cooling system. This process, lasting just a few seconds, creates a hard outer layer (martensitic structure) and a softer core (ferrite-pearlite structure). The cooling rate is precisely controlled using advanced sensors and computerized systems.
6. Tempering: The bars are reheated to about 700°C in tempering furnaces to relieve internal stresses and improve ductility. This process, lasting about 2 hours, ensures the optimal balance of strength and flexibility in the final product.

Throughout the manufacturing process, stringent quality control measures are implemented. Each batch undergoes rigorous testing, including tensile strength tests, bend tests, and chemical composition analysis, to ensure compliance with IS 1786:2008 standards. Kamdhenu's quality control laboratory is NABL accredited, guaranteeing reliable and accurate test results.
