High Alumina Refractory Cement Introduce:
High Alumina Cement (previously called bauxite cement) is a kind of grinding hydraulic cementing materials with clinker about 50% alumina content and has calcium aluminate as the main material, which is also called refractory cement, which can be made to low cement high alumina castable to build or repair all kinds of furnace and kilns for thermal insulation or acid erosion resistance with high strength.
According to the different content of Al2O3,they can have totally foue types:CA50,CA60,CA70 and CA80.CA-50, CA-70, CA-80, the alumina content is greater than 48%, 68% and 77% respectively. Its refractoriness is greater than 1650°C. The use temperature can reach 1800℃, and the impurity content is lower than other common cements.
High Alumina Refractory Cement Features and Advantages:
1. High refractoriness, high refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.
5. Good resistance to flake performance.
6. Good thermal shock stability.
7. Scouring resistance
8. Good hot strength.
High Alumina Refractory Cement Application:
1. Furnaces of metallurgy industry, heat treatment furnace.
2. Furnace of incineration of garbage, recirculating fluidized bed furnace.
3. Furnaces of chemical industry and construction industry.
Calcium aluminate CA-70/80 is used for manufacturing good property low cement refractory castable, or unshaped bulk refractory materials, which are used in high temperature, high pressure, and reducing condition. It is also high quality binder of refractory castable, which is extensively applied in chemical industry, metallurgical industry, building material, petroleum industry, ceramic industry etc.
