Product Features:

High alumina brick with Al²O³ content above 48% is a neutral refractory material, which is calcined from bauxite or other high alumina raw materials. High thermal stability, fire resistance at 1770C and above. Good slag resistance, mainly used in electric furnaces, glass furnaces, cement rotary furnaces, and other buildings.
The production technology of high-alumina bricks is similar to that of multi-clinker clay bricks. The proportion of clinker in the raw materials is high, up to 90-95%. Before the clinker is crushed, it is necessary to sort and screen iron. The firing temperature is high, such as I, ii, etc. When aluminum bricks are fired in a tunnel kiln, the temperature is generally 1500~1600℃.
Production practice in China has proved that before crushing, high-aluminum clinker is strictly screened for grades and stored in tiers. The use of alum clinker and clay combined fine grinding method can improve product quality.


a. Fire resistance.
The fire resistance of high alumina bricks is higher than that of clay bricks and semi-silica bricks, reaching 1750~1790℃, which is a refractory material.
b. Load softening temperature.
High-alumina products have high Al2O3, fewer impurities, less glass that is easy to melt, and load softening temperature is higher than that of clay bricks, but because mullite crystals do not form a network structure, the load softening temperature is not as high as silica bricks.
c. Slag resistance.
There are a lot of Al2O3 in high alumina bricks, which are close to neutral refractory materials, and can resist the erosion of acid slag and alkali slag.
