The steel industry is a sector that focuses on the production and processing of steel, a strong and durable metal used in various applications. Steel is primarily made from iron ore, which is extracted from the earth and then refined. The industry plays a crucial role in construction, manufacturing, and transportation, providing materials for buildings, vehicles, and machinery. The production of steel involves several processes, including smelting, where iron ore is heated with carbon to remove impurities. Other methods, such as electric arc furnaces, recycle scrap metal to create new steel. The industry is vital for economic growth and job creation, impacting many related sectors.
