The process of electric arc furnace steelmaking is complex and highly technical, but the basics are easy to understand. Graphite electrodes<\/a> used in eaf, which generate heat to melt iron ore and other materials and extract pure iron from them to make steel. Electric arc furnaces work similarly to traditional blast furnaces, except they use electricity rather than coal or natural gas as their energy source. In this article, we’ll explore graphite electrodes used in electric arc furnaces, who uses them and why, how much current passes through a typical EAF electrode, and how long they last before needing replacement.<\/p>
