Chrome Corundum Castable
Chromium corundum refractory castable is a castable refractory material with AL2O3 and Cr2O3 as the main components. It is a neutral refractory castable. It is composed of coarse aggregate, fine aggregate, and powder in a certain proportion, and a certain amount of binder and additives are added. The material is suitable for pouring construction and molding. During construction, add binder, coagulant and appropriate amount of water, and stir and mix to make a castable with good fluidity. When used, the ratio of coarse, medium and fine aggregates and powders to the binding agent can be adjusted as needed. The binding agents used are pure calcium aluminate cement and phosphoric acid (or aluminum dihydrogen phosphate).



Features:
Chrome corundum refractory castable has the characteristics of erosion resistance, corrosion resistance, high load softening temperature (1700℃), easy construction, good masonry density and low cost.
Application:
It can be used in metallurgy, petroleum, chemical industry, building materials, machinery and other industries. Kilns and thermal equipment.
