| 摘 要： | The reason that Al2O3-MgO-C bricks and Al2O3-Spinel-C bricks excesively expand when used in ladles at high temperature has been analysed,and the effects of spinels aadding amount and their chemical constituents on ther-mal expanion have been studied ,It is pointed out that adding amount of spinels and their chemical contents are the key factors to bring the excessive expansion of above-mentioned bricks at high temperature under control.
