Theoretical Investigation of Sintering Process

Abstract

The mineral structure of sinter is strongly affected by the heat pattern in the sintering process. For this reason, the control of heat pattern in sintering bed is an important operating factor in the sintering process of iron ore. In the theoretical investigation of sintering process, a simulation model which is considering the coke breeze size distribution, the moisture condensation reaction, the FeO formation/reoxidation reaction and other reactions are considered was developed. Many useful findings on an actual sintering operation were obtained from the study of the effects of various operating factors on the heat pattern with the aid of this simulation model.
