High Alumina Refractory Bricks

High aluminum refractory brick is a common refractory material, usually made of high bauxite as the main raw material, through high temperature calcination. It has excellent fire resistance and high temperature resistance, and is often used in a variety of industrial furnaces, melting furnaces, glass kilns and other high-temperature equipment lining and masonry. High aluminum refractory bricks usually have a high refractoriness and can withstand high temperatures of more than 1700 degrees Celsius, so they are widely used in industrial production.

High Refractoriness

Withstand long-term use in high temperature environment, not easy to deformation or damage.

Good Thermal Shock Stability

In the environment of rapid temperature changes, it is not easy to crack or break.

Good Erosion Resistance

In the environment of rapid temperature changes, it is not easy to crack or break.

Excellent Mechanical Strength

withstand a certain amount of mechanical impact and extrusion pressure, maintain the stability of the structure.

1.R efractoriness ： The refractoriness of high aluminum brick is higher than that of clay brick and semi-silicon brick, up to 1750~1790℃, which is a high-grade refractory material.

2.R efractoriness Under Load ：

Because the Al2O3 in high aluminum products is high, the impurity is less, the formation of fusible glass body is less, so the load softening temperature is higher than that of clay bricks.

3.S lag Resistance：

There are more Al2O3 in high aluminum bricks, close to neutral refractory materials, which can resist the erosion of acidic slag and alkaline slag.

Metallurgical Industry

Steel Manufacture

Glass Kilns

Industrial Furnace

In short, because of its excellent fire resistance and high temperature resistance, it is often used in various industrial kilns, glass kilns, metallurgy, steel refining and other industries.

KERUI high aluminum bricks have excellent high temperature resistance, can be used at 1400 to 1500 degrees, and have good chemical stability， Low apparent porosity of 19%-21%, alumina content between 55%-80%, can be used for a long time.
