Steel mills are industrial facilities where raw materials, primarily iron ore, coal, and limestone, are processed to produce steel. The process involves heating and melting these materials in large furnaces, then refining the molten metal to remove impurities. The resulting steel can be shaped into various products, such as beams, sheets, and rods, which are essential for construction and manufacturing. These mills play a crucial role in the economy, providing jobs and supporting industries like construction and automotive. Modern steel mills often use advanced technology to improve efficiency and reduce environmental impact, making them vital to sustainable development in the manufacturing sector.
