Analysis of the application of calcium aluminate powder in refractory materials

Analysis of the application of calcium aluminate powder in refractory materials. Calcium aluminate powder is a hydraulic binder obtained by sintering high-purity calcium oxide and alumina at a high temperature to have an alumina content of about 70-80%. Due to the high alumina content of this product, various impurity components are relatively low.

In particular, the reasonable combination of CA phase (monocalcium aluminate) and CA2 (dicalcium aluminate) makes this product not only impart high mechanical properties to amorphous refractories, but also has excellent high temperature performance, which is very suitable for high temperature. surroundings. It has the advantages of low impurity, high bonding strength and stable setting time. It is suitable for high temperature parts; excellent performance; easy to use; high working efficiency. It is mainly used to prepare refractory castables of 1500-1800 degrees or even 1800 degrees or more, especially low cement; ultra-low cement castables. Such as ladle lining, permeable brick, high-strength anti-skin anti-erosion castable for cement kiln.
