Steel production is the process of creating steel from raw materials, primarily iron ore, coal, and limestone. The most common method is the blast furnace process, where iron ore is heated with coke (a form of coal) to produce molten iron. This molten iron is then refined to remove impurities and alloyed with other elements to create different types of steel. Another method of steel production is the electric arc furnace (EAF) process, which uses recycled steel scrap as its primary input. In this method, electricity is used to melt the scrap steel, allowing for a more environmentally friendly approach. Both methods contribute to the global steel supply, essential for construction, manufacturing, and various industries.
