Abstract

método para aumentar a profundidade de penetração de um fluxo de oxigênio. a presente invenção refere-se a um método para aumentar a profundidade de penetração de penetração de um fluxo de oxigênio apresentando um fluxo de volume e um fluxo de massa que entram no leito de uma unidade de produção de minério de ferro, preferivelmente uma unidade de redução de fusão ou gaseificador de fusão ou um alto-forno de oxigênio, o dito fluxo compreendendo oxigênio tecnicamente puro para gaseificar condutores de carbono presentes no leito, caracterizado pelo fato de que a relação de fluxo de volume-fluxo de massa do fluxo de oxigênio é aumentada.
