High alumina bricks for hot blast furnaces

 
Properties: 
 
 
 
We use super bauxites to produce high alumina bricks for hot blast stoveŁ¬being high pressure pressed and sintered in high temperatureŁ¬main mineral compositions are mullite phasesŁ®These products could be used for every part of hot blast stove due to their steady volume,low creeping and well thermal shock resistance propertiesŁ®
