Abstract
PROCEDIMIENTO PARA LA REDUCCION DE MINERALES DE HIERRO EN FUSION, EN EL QUE SE REDUCE EL OXIDO DE HIERRO EN UN ESTADO ESENCIALMENTE LIQUIDO Y LA ENERGIA NECESARIA PARA IGUALAR EL BALANCE TERMICO DE LA OPERACION SE OBTIENE MEDIENTE LA ADICION A LA MASA FUNDIDA DE COMBUSTIBLES HIDROCARBONADOS Y MEDIANTE LA COMBUSTION POSTERIOR DE LOS GASES DE REACCION QUE SE FORMAN, PRINCIPALMENTE CO Y H2, PARA LO QUE LOS GASES DE REACCION SE QUEMAN POSTERIORMENTE EN FORMA DE CHORROS DE GAS OXIGENADOS QUE SE INSUFLAN, DOS VECES SUCESIVAS O MAS FRECUENTEMENTE, EN LAS CAMARAS DE REACCION QUE SON FUNCIONALMENTE INDEPENDIENTES UNA DE OTRA.
