High Strength Castable (high Alu)

Detailed Product Description

High strength castable, the type is high Alu A-75. This type of refractory castable has high crushing strength 80Mpa. The Al2O3 content is 75%, and the package is wovne bag.

Double Egret is the specialized manufacturer and exorter of refractory castable in north of China, and has the production capacity 500 tons per month, primarily export to USA, AUSTRALIA, RUSSIA, JAPAN, GREECE etc.

Refractory castable is unshaped refractory material that doesn't need firing and features fluidness after adding water. Mixed by grain, fines and binder in fixed proportion, refractory castable can replace special shaped refractory material. Refractory castable can be used directly without firing, easy to construct, and has a high utilization rate and high cold crushing strength.
    Refractory castable is primarily used for furnaces and kilns in metallurgy, petroleum, chemical industry, construction, electric power and machine building.
