摘要
针对铝镁炭砖高温下产生较大热膨胀的原因，研究了基质中引入的两种尖晶石对试样膨胀性能的影响，指出尖晶石的加入量和其化学组成是控制制品残余膨胀的关键因素。
The reason that Al2O3-MgO-C bricks excessively expand when used at high temperature has been analysed, and the effects of spinels additives in the matrix on thermal expansion have been studied. It is pointed out that the addition amount of spinels and their chemical commpition are the key factors to control the excessive expansion of above-mentioned bricks at high temperature.
