Modelamento da utilização de aglomerado autorredutor em minialto-forno com recirculação de gás de topo

Abstract: ResumoOs minialtos-fornos são reatores que, tradicionalmente, produzem gusa a partir de carvão vegetal, utilizando minério granular com alguma substituição de minério por carga elaborada. Nesse trabalho, propõe-se a substituição de carga metálica por aglomerado autoredutor com reaproveitamento de gás de topo reformado em minialtos-fornos com cenários onde o agente redutor seria o CV e retorno de coque de grandes altos fornos (small coque). Essa tecnologia foi avaliada, utilizando-se um código computacional do … Show more

“…However, a large amount of reducing gas is required, and hydrogen reduction is efficient only at high temperatures. Matos et al 17 investigated the use of self-reducing briquettes in a mini blast furnace and concluded that both the thermal reserve zone and the fuel rate decreased. A combination of these techniques was proposed by Castro et al 11 and the results showed promising features.…”
