Acid resistant castable is a kind of granular and powdery material made of refractory material with a certain amount of binder. Acid proof castable manufacturing with high fluidity and is suitable for shapeless refractories formed by pouring. Compared with other amorphous refractories, its binder and moisture content is higher, fluidity is better, so the application range of amorphous refractories is wider, according to the use of the conditions of the material used and binder to be selected. It can be directly cast into the lining, and can be cast or shaken into the precast block.
Acid Resistance Castable Feature
With easy construction, good performance characteristics of acid erosion, chimney and other parts for the power industry.

Acid Proof Castable Application
As the main varieties of amorphous materials, acid resistant refractory castable has the common characteristics of direct use without firing. Among various amorphous materials, the production process is relatively simple, no special equipment is needed, high degree of mechanization is required, construction is the most convenient and material utilization rate is high. In addition, Acid proof castable manufacturing generally has a higher strength at room temperature, and can be made into prefabricated parts to be installed in the kiln, such as chimney lining pouring. Acid proof castable is mainly used in metallurgical industrial kilns, but also widely used in petroleum, chemical, building materials, electric power and mechanical industry kilns and thermal equipment.
