摘要

为了指导烧结生产配矿,利用高温性能特征数对铁矿粉的高温性能进行研究。铁矿粉的高温性能特征数结合了烧结过程的各种信息参数,从而能够更加准确、全面地表征烧结铁矿粉的高温基础特性。在对7种单一矿粉进行实验分析的基础上,按照其高温性能差异,将混合矿粉中的等性能矿粉进行置换,分析置换前后混合矿的高温性能变化,并通过工业实验,验证置换前后烧结矿的质量波动。实验结果表明,在一定比例范围内,等性能矿粉置换,混合矿粉高温性能特征数变化不大,高温性能稳定,生产出烧结矿转鼓强度保持在稳定水平,质量满足高炉生产要求。可用于指导烧结配矿,为实际烧结生产提供参考依据。
        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.
