Calcined bauxite aggregate is of great importance to refractory materials. Such calcination of bauxite has the properties of high alumina, low iron, high hardness, small thermal expansion coefficient, high refractoriness, and stable thermal chemical performance, so it is the main raw material of producing alumina and artificial corundum refractory materials, and can be used in the thermal equipment, such as electric furnace, blast furnace and hot blast furnace.
Bauxite aggregate is the basis of the refractory material, which is made of bauxite after material selecting, high temperature roasting, grinding, classifying, and other process, being made into high quality refractory materials. and the main chemical compositions of bauxite are Al2O3, SiO2, Fe2O3, TiO2, and the minor components are CaO, MgO, K2O, Na2O, etc.
Properties of Calcined Bauxite Aggregate
It is high alumina sand, or high alumina aggregate, refers to the sintered bauxite aggregate, which is a kind of refractory aggregate, it is also called calcined bauxite aggregate, or calcined bauxite. So it is an artificial aggregate with higher strength and hardness than natural bauxite. People buy bauxite aggregate mainly used in the mortar or refractory concrete with high strength and high wear resistance.
Chemical Components:Al2O3, SiO2, Fe2O3, TiO2 and CaO, MgO, K2O, Na2O, etc.
Properties: High strength,high hardness, high wear resistance, etc.
Bauxite aggregate is mainly used in the construction industry, building materials, refractory industry, and castable. In detail, calcined bauxite uses as follows:
Bauxite Aggregate Usages：
Being made into refractory bricks. They are widely used in the electric furnace, blast furnace, and hot blast furnace;
Being used directly as unshaped refractory, such as bauxite cement, abrasive materials, iron trough, industrial alumina and other unshaped refractories, such as ladle castable and refractory castable in a certain propotion.It also can be used in the industrial aluminium and precision casting, chemical industry, and ceramic industry, etc.
China is rich in bauxite resources, especially the central part. Henan Province is the most representative place with large amount of bauxite resource. We are one of calcined bauxite manufactures, specialized in the refractory material for about 20 years with the trust given by our customs foreign or at home. Compared with the other manufactures, calcined bauxite price from RS is lower than any other refractory manufacturers, but provide superior quality and services.
