Theory and Practice of Sintering of Iron ore IspatGuru

Theory and Practice of Sintering of Iron ore IspatGuru

The process of sintering is a thermal operation involving melting and assimilation reactions. The first stage of the sintering process is the formation of the melt which involves the reaction between fine iron ore particles and fluxes. The initial melt is generated from adhering fines during heating via reaction between iron ore and fluxes.
