Product Description

High Alumina Refractory Cement Description

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.

High Alumina Cement Advantages 

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.

Product Application

High Alumina Cement Application

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.
