| 摘要 |
The invention relates to precluding the shortcomings intrinsic to the conventional unburned carbon-containing refractory bricks, i.e., oxidization under high temperature conditions and the incidental decarbonization, the phenomenon of exfoliation and detachment of the fragile layers, and more particularly to obtaining thereby unburned carbon-containing refractory bricks having the high properties by causing refractory brick material comprising substantially more than 1 weight % carbon to contain 1-10 weight % aluminum powder and/or magnesium powder each independently or in a mixture thereof, and/or 0.5-6 weight % silicon powder. |
