High Alumina Brick

High Alumina Brick
Product Detailed
Related Categories:Refractory
high alumina brick,Comprtitive Chinese price with good quality Features Specifications: high alumina brick

For high alumina bricks the temperature of refractoriness under load is normally above 1420~1550 that is higher than the clay brick and it increases along with the AL2O3 content enhances.For high alumina bricks the thermal shock resistance is mainly decided by chemical contents and its mineral microstructure but its thermal shock resistant is worse than the clay brick.High alumina bricks have very good ability of anti-acidity, anti-metal fluid corrode and   anti-oxidation.The high alumina bricks are used normally in industry furnaces such as Blast furnace, hot-blast furnace and EAF etc.High alumina bricks packingBricks are packed on wooden pallet and then polyethylene film is placed over it, finally the package is tied up with steel strips.High alumina bricks order quantity20 t as minimum quantity is accepted.High alumina bricks delivery time30 days after receiving L/C or 30% of advanced T/T. the production capacity reach to 3000 t per month.
