Insight into the high proportion application of biomass fuel in iron
Iron ore sintering is an essential stage among the whole steelmaking flow, the function of which is to process iron ores (<8 mm) into lumpy sinter, thereby providing raw materials for ironmaking (Clout and Manuel, 2003, Remus et al., 2012, Forsmo et al., 2008).In China, sinter takes up around 75% of the total iron-bearing burden of ironmaking (Wang and …
