Steel Manufacturing (Including Blast Furnace and BOS)

Steel is a versatile material used in various industries like cars, buildings, bridges, ships, and more. The process of making steel involves converting molten iron into steel by removing impurities and adding elements to adjust its properties.

The transformation process involves converting iron ore into steel through a series of steps like sintering, coke production, and removing impurities by blowing oxygen onto molten iron. Other elements are added to tailor the steel for specific purposes.

The refining process further enhances the quality of steel by reducing carbon content, adding or removing elements, and adjusting the composition using gases like argon, nitrogen, or oxygen. This stage ensures the steel is suitable for various applications.

The EAF process utilizes cold steel scrap and electric current to melt steel quickly. Alloying elements can be added to meet specific customer requirements, allowing for the production of different types of steel, including alloy steels and stainless steels.

Continuous casting solidifies molten steel into billets, plumes, and slabs, which are then shaped into finished products like beams and sections. The process involves controlling temperature and ensuring the steel maintains its form during casting.

Steel rolling involves shaping steel into various forms by passing it through rolling mills. The process can be hot or cold rolling, and it plays a crucial role in producing flat products, beams, sections, and bars with precise dimensions and finishes.

Steel tubes are produced through welding or seamless processes. The tubes undergo sizing operations and can be further coated for protection or decoration, catering to a wide range of applications in industries.

The steel industry supports various industries with its versatile properties and plays a vital role in meeting global demands. Continuous advancements in steel production lead to the development of new types of steel to meet evolving needs and sustainability requirements.
