Abstract
Basic technological, energy and design innovations enabling to achieve up-to-date performances of electric arc furnaces (EAFs) are considered. These innovations such as: increases in electrical power, furnace capacity, and intensity of carbon and oxygen injection into the bath; slag foaming; single scrap charging; etc., have already exhausted their capabilities in general. Prospects of further development of EAFs are associated with the new technology of continuous charging a scrap into the bath and melting it in liquid metal. This revolutionary technology partially implemented in operating conveyor and shaft furnaces creates new possibilities for sharp increase in productivity and reduction in electrical energy consumption. Analysis of these potentialities is given.
