A complex of low-cost energy-efficient solutions for the modernization of electric arc furnaces was proposed: a deep pool, water-cooled panels with a spatial structure, a system of distributed aspiration and preliminary medium-temperature heating of a scrap by a powder-gas environment with an efficient extra burning of CO. Applying the methods of computer simulation, it was shown that using a complex of solutions in a 120-ton electric arc furnace can reduce energy consumption by 56...68 kW∙h/t. Ref. 29, Tabl. 6, Fig. 7.
Key words: electric arc furnace; energy efficiency; deep pool; water-cooled elements with volumetric structure; distributed aspiration system; medium temperature preheating of scrap
