Abstract
PROCESO PARA LA FUSION DE UNA CARGA EN EL HORNO, CON POST-COMBUSTION DE LOS HUMOS POR INYECCION DE UN GAS OXIGENADO EN LA ATMOSFERA DEL HORNO EN FORMA DE UNA SERIE DE CHORROS QUE CIRCULAN SEGUN UN COMPONENTE TANGENCIAL EN EL ESPACIO COMPRENDIDO ENTRE LOS ELECTRODOS (7-8-9) Y LA PARED CILINDRICA DEL HORNO (3), SEGUN UNA DIRECCION DE INYECCION DE MODO QUE SE FORME UNA CORRIENTE DE GAS ROTATORIA ALREDEDOR DEL EJE VERTICAL DEL HORNO, Y PREFERENTEMENTE EN AL MENOS DOS SERIES SOBRE DOS NIVELES ESCALONADOS (N SUB 1-N SUB 2) DE MANERA QUE SE FORMEN CORRIENTES DE GAS ROTATORIAS QUE GIRAN EN SENTIDO INVERSO. APLICACION EN HORNOS ELECTRICOS PARA LA PRODUCCION DE ACERO O DE ALEACIONES DE HIERRO.
