Description

High alumina refractory cement (also called calcium aluminum cement, or high alumina refractory binder), high alumina refractory cement is made by grinding alumina and calcareous material such as lime through sintering or fusing. High alumina refractory cement differs from the production of ordinary concrete. This is because it essentially uses bauxite and lime as the raw material. They are mixed following the set amounts which will be grounded into 100mm fragments. Then, the fragments enter a kiln to heat up to their fusion point (1600°C). The molten product is then transferred down a steel plate to cool in a rotary kiln. Afterward, it is finely grounded into tube mills until the product is at 2250cm²/gram.

High alumina refractory cement can bind various kinds of refractory aggregates (such as corundum, and burned high alumina bauxite). And it is used to produce refractory mortar or refractory concrete. Usually, the material is applied in the inner wall of cement rotary kilns and other refractory kilns and furnaces.

Applications of High Alumina Refractory Cement
It's mainly used for furnace lining of boilers, blast furnace hot blast stoves, heating furnaces, ceramic kilns, and various industrial furnaces.
