A steel mill is an industrial facility where steel is produced from raw materials. The process typically involves melting iron ore, along with other elements like coal and limestone, in a furnace. This molten metal is then refined and shaped into various products, such as sheets, beams, and rods, which are essential for construction and manufacturing. Steel mills can vary in size and complexity, with some operating as integrated mills that handle everything from raw material processing to finished product delivery. Others may function as mini-mills, focusing on recycling scrap metal to produce new steel. Both types play a crucial role in the global economy.
