Product Description
High Alumina 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.
Refractory Cement Applications
The application industries of refractory cement include metallurgy, building materials, machinery, petrochemicals, ceramics, glass, boilers, electricity, steel, cement, etc. Mainly used in coke ovens, glass furnaces, blast furnace hot blast furnaces, and other industrial kilns.
Refractory cement is a high-quality binder that can be used to make high-performance low cement and high aluminum castables, refractory concrete, ramming materials, gunning materials, and other castables, or unshape block refractory materials used under high temperature, high pressure, and reducing conditions.Used for building or repairing various high-strength insulation or acid resistant kilns, etc.
