Abstract

método de fabricação de ferro reduzido. a presente invenção refere-se a um método de fabricação de um ferro reduzido que inclui: um processo de amassamento com a adição de um fluido a 60°c ou mais e 90ºc ou menos a uma mistura de um material de óxido de ferro e um agente de redução, ambos os quais estão em uma forma em pó, e amassar a mistura; um processo de peletização com a aglomeração da mistura após o processo de amassamento formando uma substância aglomerada; e um processo de redução com a redução de substância aglomerada após o processo de peletização, para através disso produzir o ferro reduzido.reduced iron manufacturing method. The present invention relates to a method of making a reduced iron which includes: a kneading process by adding a fluid at 60 ° C or more and 90 ° C or less to a mixture of an iron oxide material and a reducing agent, both of which are in a powdered form, and kneading the mixture; a pelletizing process with agglomeration of the mixture after the kneading process forming a agglomerated substance; and a reduction process with the reduction of agglomerated substance after the pelletizing process to thereby produce the reduced iron.
