castable refractory material high Temperature high alumina refractory cement for furnace
Introduction of high alumina refractory cement:
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.
Feature of high alumina refractory cement:
1. high temperature
2. high alumina
3. easy to construction
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.
