Evaluation of sinter properties during reduction has been studied by a new method on quantification of sinter microstructure (mineral components and porosity). (1) Reduction degradation index is expressed by number of 100∿300μm grain size of hematite. (2) Reduction index is described by quantity of Ca-ferrite and porosity consisted of pore size less than 150μm. (3) Pressure drop during softening test under load is indicated by quantity of slag and total porosity. The pressure drop increases with increasing slag quantity and decreasing the total porosity. (4) Temperature at beginning of melt-down is estimated by quantity of Ca-ferrite and total porosity. The above results are not only statistical, but also substantial because these are supported by investigation during reduction. So these are applied to indices of sinter evaluation.
