测定高铝砖重烧线变化率的新方法

A New Method for Determining Reheating Linear Change Rate of High Aluminum Brick

在测定高铝砖试样的重烧线变化率时 ,用抽真空—液体静力称量法和直接浸液法作了对比试验。结果表明 ,前者测得的结果重现性、稳定性更好 ,而用后一种方法时间因素对试验结果的影响较大 ,建议用前一种方法测定致密耐火制品非标准试样的重烧线变化率。

In determining reheating linear change rate of high aluminum brick sample, the contrastive experiments are done with the evacuation hydrostatic weighing method and the direct immersion method when are determined. The results show that the reproducibility and stability of the former are better, and in the latter, the time factor affects greatly experiment results, therefore, it is suggested that determining reheating linear change rate of the nonstandard samples of dense refractory products with the former.
