Abstract

Procedimiento para controlar un proceso de reducción por fusión, en particular el proceso de un horno convertidor de ciclón para producir hierro en lingotes, caracterizado porque: mide la fracción de carbono C en el gas de escape en la forma de CO y CO{sub,2}; mide la fracción de hidrógeno H{sub,2} en los gases de escape en la forma de H{sub,2} y H{sub,2}O, determina la relación C/ H{sub,2} en los gases de escape, compara la relación C/ H{sub,2} determinada en los gases de escape contra la relación C/ H{sub,2} predominante para el carbón que está siendo suministrado, y ajusta el carbón suministrado en base a la diferencia encontrada entre las relaciones de C/ H{sub,2} en los gases de escape y en el carbón que está siendo suministrado.
