Abstract
método de avaliação de minério aglomerado e minério aglomerado. é fornecido um método de avaliação de minério aglomerado que pode avaliar o agrupamento de ferro reduzido quando ele foi reduzido a uma alta concentração de hidrogênio, com compensação térmica usando calor sensível a sopro levado em consideração. neste método, o minério aglomerado é reduzido enquanto é submetido a uma carga predeterminada de 1000ºc a 1200ºc, ambas incluídas, para produzir um agregado reduzido; um tratamento de rotação é realizado no agregado reduzido usando um testador de rotação; a resistência do grupo cs do agregado reduzido calculado pela fórmula (1) abaixo é medida; e uma propriedade de agrupamento do minério aglomerado é avaliada usando a resistência do grupo cs: cs = (w'/w) x 100 ... (1), onde cs é a resistência do grupo (% em massa); w é a massa (g) de agregado reduzido igual ou maior que o diâmetro de partícula máximo do minério aglomerado; e w' é a massa (g) de um agregado reduzido após um tratamento de rotação no testador de rotação que é igual ou maior que o diâmetro de partícula máximo do minério aglomerado.
