Alkali Proof Castable Description

Alkali proof castable has high liquidity and is suitable for unshaped refractory materials made with pouring type. Alkali proof refractory castable has various features of high temperature resistance, high mechanical strength and strong acid erosion resistance for all kinds of furnaces and kilns application. Alkali proof castable can react with metal oxide at high temperature generating high viscosity liquid products, which forming a glaze layer avoiding the penetration and erosion of the alkali melting metal.

Properties of Alkali Proof Castable

• Long service life,
• High strength,
• Low bulk density,
• High refractoriness.

Manufacturing Process of Alkali Proof Castable

Alkali proof refractory castable is made of refractory aggregates, binders and alkali resistance powder. Its aggregates are ceramsite, sticky soil clinker, waste porcelain material, high strength expanded perlite, etc. together with calcium aluminate cement and sodium silicate as binders.

Classification of Alkali Proof Castable

According to different conditions and environments, alkali proof castable can be divided into light alkali proof castable and heavy alkali proof castable. Those with porosity greater than 45% are light alkali proof castable and those with porosity less than 45% are heavy alkali proof castable. The heavy quality alkali proof castable can be divided into medium temperature alkali proof castable and high temperature alkali proof castable.
