Low Creep High Aluminum Refractory Brick for Hot Blast Stove
Refractory bricks are mainly made from chamotte, flint clay and combining clay powder, being high pressure pressed and sintered in high temperature.
Low porosity bricks are made from low mullite stones, the main mineral composition of the low mullite stones are pressed and sintered mullite phases. The bricks have very good physical and chemical properties in high temperature conditions.
We offer an exclusive range of refractory bricks which are of optimum quality. Our range encompasses of refractory bricks, High Alumina Low Ferric Fire Bricks etc which are highly exclusive. We offer different shapes and sizes in our High Alumina Bricks which cannot be availed through anywhere else. We use the best quality material to manufacture our refractory bricks so that there is no compromise in their quality. We offer our refractory bricks at quite reasonable prices and also deliver them well within the stipulated time avoiding all delays.
Refractory bricks are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. It(High Alumina Brick,Alumina Brick,Refractory Alumina) features excellent high temperature mechanics and chemical corrosion resistance.
