Abstract
Official abstract text for this publication.
A method for supplying energy to a scrap metal pile ( 9 ) in an electric arc furnace ( 2 ). Energy is supplied by jets of hot gas in a first phase. Energy is supplied by electric arcs in a second phase after the first phase is completed. Hot gas is supplied via at least six jets. A device ( 1 ) for the method has an electric arc furnace ( 2 ), one or more blowing devices ( 6 a, 6 b, 6 c ), supply jets of reactant hot air into the chamber ( 7 ) of the electric arc furnace ( 8 ). The devices have a total of at least six nozzles ( 10 a, 10 b, 10 c, 10 d, 10 e, 10 f ) with nozzle openings. Fuel conducting devices ( 8 ) supply fuel to the jets of reactant hot air.
First claim
