Product Description

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.

Advantages of Refractory 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.
