FEATURE
Very High Refractoriness
The refractoriness of alumina refractory bricks is higher than that of clay bricks and semi-silica bricks, at 1750-1790C, which belong to advanced refractory material
High Load softening temperature
It has high AI203, less impurities and less fusible glass bodies, the load softening temperature is higher than that of clay bricks
Good Slag resistance
alumina refractory brick contain more Al203, which is close to neutral refractory materials, andit can resist the erosion of acidic slag and alkaline
Low thermal conductivity and good thermal insulation performance
