High Alumina Refractory Cement Introduce
Calcium aluminate cement/aluminate cement/high alumina cement are collectively referred to as refractory cement. High alumina cement (formerly known as bauxite cement) is a hydraulic cementing material made of high-purity calcium materials and high-purity alumina as the main raw materials, and clinker with alumina content of about 50%.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 1800ºC, and the impurity content is lower than other common cements.
Advantages of High Alumina Cement
1.High refractoriness, up to 1650ºC±50ºC;
2.High density, low porosity.
3.High strength and wear resistance.
4.Good thermal exfoliation.
5.Good resistance to slag invasion;
6.Good plasticity and convenient construction;
7.High bonding strength
8.Good thermal shock stability.
Application of High Alumina Refractory Cement
High alumina cement is mainly used to configure refractory castable such as high alumina low cement castable which can build or repair furnace or kiln for heat insulation or high temperature erosion.
