Steel Production From Electric Arc Furnace

This report provides a detailed cost evaluation of steel production from electric-arc furnace. This report offers a detailed cost evaluation of steel production using an electric-arc furnace (EAF). In this process, scrap steel is loaded into the EAF from the top. Once the furnace is filled, the lid, equipped with electrodes, is closed. These electrodes are charged with a strong electric current that generates intense heat, melting the scrap steel. Subsequently, additives such as ferro-alloys are introduced to achieve the desired steel composition. Oxygen is also injected into the furnace to purify the steel. Throughout this process, impurities react with lime and fluorspar (which are added as flux materials) to form molten slag, which rises above the molten steel. This slag is then removed by tilting the furnace to pour it out.
