Steel Production - American Iron and Steel Institute

The use of EAFs has expanded and now accounts for nearly 2/3 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 and/or direct reduced iron. The EAF uses scrap steel and electricity to produce molten steel.
