the electric arc furnace

An electric arc furnace (EAF) is a type of industrial equipment used to melt scrap metal or raw materials using intense heat generated by electric arcs. Large electrodes create electrical arcs when electricity passes through them, heating the metal to its melting point. This process is quick, efficient, and environmentally friendly compared to traditional blast furnaces, as it can be powered by renewable energy sources. EAFs are mainly used in steelmaking, allowing for precise control of composition and recycling of scrap metal, thereby reducing waste and environmental impact.
