Abstract
"MACROPELOTAS E PROCESSO DE SUA PRODUçãO". Em que as macropelotas posuem dimensões de 14 a 25mm, e agregam carvão, calcário e bentonita como aditivos, sendo que o processo de produção das macropelotas compreende as etapas de: a) adicionar, a um concentrado de minério de ferro finamente moído(88% < 325#), aditivos: H~ 2~O, carvão, calcário e bentonita; b) fazer rolar, num prato pelotizador, tal concentrado, provocando aglomeração do material, e formando as pelotas cruas; c) classificar as pelotas através de seus tamanhos, selecionando as de tamanho entre 14 e 25mm (onde as pelotas menores de 14mm e maiores de 25mm são desviadas para um disco pelotizador); d) queimar as pelotas em forno de grelha móvel, onde há sinterização das pelotas (entre os elementos óxidos), conferindo às pelotas resistência mecânica adequada à produção de ferro gusa e ferro esponja; e) encaminhar as pelota na faixa de 14-25mm de tamanho a um pátio de estocagem.
