Electric Arc Furnace Design Operation and Working Principle

The Second World War saw a steep increase in the use of these furnaces leading to the modern Electric Arc Furnace design operation and working principles. These improvements to the processing of scrap steel comprised of larger more efficient and higher capacity furnaces; a 100T furnace would process the scrap in about an hour, using a transformer of 60MVA capacity.
