Electric arc furnace · An electric arc furnace (EAF) is a furnace · Industrial arc furnaces range in size from small units of approximately one-tonne capacity . The present day UHP EAF has several sub-processes which have contributed to its remarkable productivity and efficiency. Power-off time is now less than 10 minutes (min) for the best operated furnaces. For a large number of EAFs, average electrode consumption is around kilograms per ton (kg/t). The cost is for a notional producer - a typical size plant of about 1m t/year capacity, based in Japan, using a % scrap charge to EAF [no DRI or irons], and producing commodity grade carbon steel for long products with average labour productivity. The steel product for which the cost is shown above is a metric tonne of EAF liquid steel. Although electrical arc furnaces (EAFs) are reliant on large amounts of electricity, it is fairly cheap and in certain circumstances, cheaper than using.
