发明名称 METAL CONTAINING COMPOUND REDUCTION AND MELTING PROCESS
摘要 A metal containing compound reduction and melting process which entails feeding a burden (15) comprising a mixture of the metal containing compound and a suitable reductant in particulate form into an electrically heatable vessel (11) which contains a bath (18) of the said metal in liquid form so that a reaction zone is formed in the burden (15) in which the metal containing compound (15) is reduced and a malting zone (23) is formed below the reaction zone in which the reduced metal is melted; and controlling such process in such a manner that substantially all of the reduction of the said metal containing compound takes place in the solid phase. Apparatus for carrying the said process into operation comprises a single compartment (11) channel type induction furnace (10) in which the said reduction and melting are carried out, the compartment (11) being provided with at least one feeding port (13, 14) for the burden (15); at least one exit port for the liquid metal product; and at least one exit port for any slag formed in the reaction.
