A steel mill is an industrial facility where steel is produced from raw materials. The process typically involves melting iron ore, along with other materials like coke and limestone, in a furnace. This molten metal is then refined and shaped into various products, such as steel beams, sheets, and rods, which are used in 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. These facilities play a crucial role in the global economy by supplying essential materials for various industries.
