Abstract

método para produzir minério aglomerado, método para produzir ferro reduzido, minério aglomerado, máquina de sinterização e forno de queima de pellet. para fornecer um método para produzir minério aglomerado, com o qual o ferro reduzido pode ser produzido de maneira eficiente pela redução de hidrogênio, sem a necessidade de pré-aquecer a matéria-prima e elevar a temperatura do gás redutor. um método para produzir minério aglomerado, o método incluindo sinterizar uma matéria-prima de sinterização que contém uma matéria-prima contendo ferro e um material de condensação na máquina de sinterização para formar um bolo de sinterização, e obter o minério aglomerado ao esmagar o bolo de sinterização, no qual o óxido de ferro contido no bolo de sinterização é reduzido ao distribuir um gás redutor através do bolo de sinterização na máquina de sinterização, para atingir um grau de redução de óxido de ferro contido no minério aglomerado depois de esmagar 50% ou mais.
