Abstract

LA INVENCION SE REIFIERE A UN HORNO DE REDUCCION ELECTRICO PARA LA EJECUCION DE PROCESOS DE REDUCCION, ESPECIALMENTE PARA LA REDUCCION DE ESCORIA PARA LA RECUPERACION DE COMPONENTES METALICOS. ESTE TRABAJA MEDIANTE LA ENERGIA ELECTRICA, LA QUE ES ALIMENTADA AL INTERIOR DEL HORNO MEDIANTE AL MENOS UN ELECTRODO. EL HORNO DE REDUCCION PRESENTA CONSTRUCCION HERMETICA AL AIRE CON UNA ABERTURA DE CARGA PARA LA ALIMENTACION DE MATERIAL EL QUE ES TRANSPORTADO MEDIANTE UNA INSTALACION DE ALIMENTACION DONDE LA ABERURA DE CARGA SIMULTANEAMENTE SIRVE COMO SALIDA DE GAS PARA EL GAS QUE SE FORMA.
