SMU Electric-Arc Furnace Status
Electric-Arc Furnace Status
SMU tracks North American steel mills that use electric-arc furnaces (EAFs) to produce flat-rolled steel from scrap, pig iron, and DRI/HBI. Unlike blast furnaces, EAFs can be turned on and off and do not need to run at a steady state. For this reason, their operational status is usually listed as “running” unless we are aware of a major maintenance project that would take a furnace offline for an extended period. The table below includes information on plant names, city and state locations, furnace capacity, products, and the number of vessels.
