Abstract

Abstract:In order to guide the ordination of sintering production, high temperature performance characteristic numbers were used to study the high temperature performance of iron ore fines. The high temperature performance characteristic numbers of iron ore powder combined with various information parameters of sintering process, which could characterize the high temperature characteristics more accurately and comprehensively. Based on the experimental analysis of 7 single ore fines, different kinds of equal performance ore fines in the mixed ore were replaced according to their high temperature performance difference, and the high temperature performance of the mixed ore after replacement was analyzed. Then the quality fluctuation of sintered ore before and after replacement was verified through industrial experiments. It is found through the experiments that within a certain percentage, the high temperature performance characteristic numbers of mixed ore powder change little and the high temperature performance of the mixed ore remains stable basically during the equal performance replacement. The tumbler strength of sinter is maintained at a stable level, and the quality meets the requirement of the blast furnace production, which can be used to guide the ore proportioning and provide reference for actual sintering production.

Key words
