中文摘要：

利用“高温性能特征数”对铁矿粉的高温性能进行评价，在对单种铁矿粉的高温性能进行实验分析的基础上，增加了对混合矿高温性能的实验研究。通过对铁矿粉的两两混合、三三混合及四四混合进行实验，以此来揭示混合矿的高温性能与单种矿高温性能之间的关系。经实验研究发现，混合矿的高温性能与单种矿的高温性能近似满足线性相关性，其可用来指导配矿。

英文摘要：

The＂ high temperature performance characteristic numbers＂ were adopted to evaluate the high-temperature performance of iron ore fines. Based on the experimental analysis of high temperature performance of single type of iron ore fines, the experimental study on high temperature performance of mixed ores was added. By experiments of mixing two kinds of iron ore fines, mixing three kinds of iron ore fines and mixing four kinds of iron ore fines, the relationship between high temperature of single type of ores and high temperature of mixed ores was presented. It is found through the experiments that, the high temperature of single type of ores and high temperature of mixed ores are close to meet the linear correlation, which can be used to guide the ore proportioning.
