摘要天然块矿的爆裂指标作为评价矿石最重要的指标之一，其好坏会直接影响高炉的透气性，进而影响高炉顺行。对天然块矿爆裂性能的研究，有利于为合理搭配入炉炉料结构提供相应的依据。研究了4种天然块矿在不同温度下的爆裂性能，以及天然块矿爆裂性能的主要影响因素。试验表明：随着温度的不断升高，4种天然块矿爆裂后的粒级分布以及爆裂指数呈现不同的变化规律，而不同类型的天然块矿在同一温度下的爆裂指数也不尽相同。天然块矿中羟基的质量分数越高，其爆裂性能越强烈。块矿孔隙总体积和微孔平均直径的减小也会导致块矿的爆裂性能升高。

Abstract：One of the most important indexes to evaluate lump ores is the decrepitation performance of natural lump ores，which could influence the permeability of blast furnace and affect?blast?furnace?to stabilize?direct?motion. It is helpful to provide basis for matching furnace?charge structure at the study of decrepitation performance of natural lump ores. This paper researches four different kinds of decrepitation performances of natural lump ores at different temperatures and the main factors influencing the decrepitation performance. The results show： as the temperature rises， the?size?distribution and decrepitation indexes of four kinds of lump ores change differently. Moreover， the different natural lump ores have different decrepitation indexes at the same temperature. The more amount of hydroxyl contents， the stronger of decrepitation performance of natural lump ores. The decrepitation performance of natural lump ores will decrease with the increase of total volume of?pore and average diameter of pores.
