Steel manufacturing is the process of producing steel from raw materials, primarily iron ore, coal, and limestone. The main methods include the blast furnace process, where iron ore is smelted with coke, and the electric arc furnace method, which recycles scrap steel. These processes involve heating and refining to remove impurities and create various steel grades. Once produced, steel can be shaped and finished into different products through processes like rolling, forging, and casting. Steel is widely used in construction, automotive, and manufacturing industries due to its strength, durability, and versatility.
