Iron Ore To Sintering To Steelmaking Analyzing Metals

Mar 09 2013 Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore return fines recycled products of the steel plant industry (such as mill scale blast furnace dusts etc ) slag forming elements fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered productAbstract In its most basic form the process of sintering is very simple and has been in use since the turn of the previous century However while the basic process is simple control of the process relies on a number of extremely complex interdependent process parameters and requires a thorough understanding of the effect of these parameters on production capacity and product quality
