An overview of iron ore assimilation during particle sintering
B Sai PRAKASH, Sriniwas DVARPUDI
Abstract. Sinter is a precursor input to blast furnace with specific strength, reducibility and chemistry requirements. Assimilation is the primary reaction at the beginning of the sintering process which plays a key role in the obtained sinter properties for blast furnace requirements. The various theories of assimilation in combination with quantification methods were delved into.
