Industrial Furnaces Alumina Silica Refractory Brick
Industrial Furnaces High Alumina Silica Refractory Bricks
The series of bricks contain Al2O3 content is 30%-48%,SiO2 content is 50%-65%,and a small number of alkali metals,alkaline earthmetal oxides TiO2,Fe2O3 etc.Made by flint clay clinker and binder,through Crushing,Mixing,Shaping,Drying and high temperature Sintering.
Its feature is excellent physical and chemical properties in high temperature,low thermal conductivity and low impurity.It widely used in variety of furnace lining as Reheating Furnace,Blast furnace,Coke Oven,etc.
