Strength Controlling Factors and Their Model for Iron Ore Sinter

Abstract

Strength is the basic characteristic of sinter manufactured by the agglomeration process. A fundamental study was carried out for the analysis of the controlling factors of sinter strength and a quantitative prediction model for sinter strength was developed. Sinter strength was described in terms of the porosity, the mineral composition and the melting ratio of sinter on the basis of the strength model of the porous materials. The calculated strength by the model was in relatively good agreement with the observed one on the various sinter.
