Chrome-Corundum prefabricated parts with High Strength good corrosion resistance
Chromium corundum refractory castable is a castable refractory material with AL2O3 and Cr2O3 as the main components, which is a neutral refractory castable. It is composed of coarse aggregate, fine aggregate, and powder according to a certain proportion, and add a quantitative binder and admixture, the material is suitable for casting construction molding. During construction, the binder, coagulant and appropriate amount of water are added, and the castable with good fluidity can be made by mixing. The ratio of coarse, medium and fine aggregates and powders to the binder can be adjusted according to needs. The binder used is pure calcium aluminate cement and phosphoric acid (or aluminum dihydrogen phosphate).
