Abstract
La invencion se refiere a un método para incrementar la efectividad de la reduccion de fundicion de portadores de metal oxídico, particularmente mineral de hierro, y mejorar la eficiencia térmica de los combustibles cargados en el proceso de reduccion de fundicion que tiene lugar en un recipiente de reaccion que contiene un baño derretido con una capa de escoria y donde los gases de reaccion que escapan del baño derretido son post-quemados con gases oxidantes, el calor resultante siendo transferido al baño derretido y los agentes reactivos, mineral y carbon, son alimentados al fundidor al menos en parte desde la porcion superior a través del espacio para gases del recipiente de reaccion, donde estos agentes reactivos, mineral y carbon son añadidos en una forma compacta al baño derretido como un material compuesto con o sin sustancias adicionales de escolta.
