Apr 02 2010018332Like other sintering processes iron ore sintering converts iron ore fines of often 8 mm sizing into larger agglomerates namely sinter between 5 and 50 mm particle size which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation As shown in Figure 141 iron ore sintering is carried out in three stages raw material.
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron The only source of primary iron is iron ore but before all that iron ore can be turned into steel it must go through the sintering process Sinter is the primary feed material for making iron and steel in a blast furnace.
Alumina during ironmaking enters the process through impurities in the input materials mainly iron ore Alumina affects the sintering of iron ore The most harmful effect of alumina is to worsen the RDI reduction degradation index value of sinter RDI value increases as the alumina content rises.
