The first electric arc furnaces (EAFs) appeared in the late 19th Century. The use of EAFs has expanded and now accounts for over 70 percent of steel production in the United States. The EAF is different from the blast furnace as it produces steel by using an electrical current to melt scrap steel, direct reduced iron, and/or pig iron, to ...

These furnaces are typically charged with scrap steel. They use high-power electric arcs to melt the scrap. They also convert direct reduced iron into liquid steel, reaching the same quality that can be achieved in an integrated steel plant. The electric arc furnace creates valuable slag as a by-product, just as the blast furnace does. Just as in the basic …
