以漂珠隔热耐火材料为研究对象,通过调整漂珠的添加量（25%、35%、65%和85%）来改变试样的气孔结构参数,并研究了漂珠的添加量对试样气孔结构参数的影响,分别借助于回归分析理论和灰色关联理论探讨了试样的气孔率、以及气孔孔径区间等气孔结构参数与热导率之间的相关性。结果表明,随着漂珠添加量的增加,试样的闭口气孔率显著增加,但开口气孔率变化不明显;各组试样气孔孔径分布范围为1～300#m,其中以50～100#m孔径区间的气孔为主。在一定温度范围内,试样的热导率随着总气孔率的增大而呈指数关系减小;不同孔径区间与热导率的灰色关联分析表明,〈150#m范围内的气孔与热导率的关联度最大。

Pore structure parameters of cenosphere insulating refractory were changed by adjusting the content of the cenosphere additive(25%,35%,65% and 85%,respectively).The influence of cenosphere additions on pore structure parameters of the specimens was investigated.Based on the regression analysis and gray relational theory,the correlation of porosity and pore size distribution with thermal conductivity of the specimens was analyzed.The results showed that closed porosity of the specimens was increased significantly with increasing of cenosphere additive content;however,the apparent porosity didn't change obviously.The range of pore size distribution of the specimens was about 1-300μm,however,the pore diameter was mainly distributed in the range of 50-100μm.In a certain temperature range,the thermal conductivity related to the total porosity by an exponent function and the dependence exponent decreased as the total porosity increased.Based on grey relation theory,the study of correlation of pore size interval with thermal conductivity indicated that the pore size interval of 150μm had the highest correlation index.
