Description
Alkali-resistant refractory castable is made of silica alumina materials as aggregates and powders, aluminate cement as a binder, and appropriate additives. They are hydraulic refractory castables with good alkali resistance.

Applications
- In chemical industry, alkali resistant castable can be used for the lining of reactors and furnaces in the production of soda ash and caustic soda to prevent the corrosion of alkaline media on the equipment.
- In the waste incinerators and desulfurization and denitrification equipment of power industry, alkali-resistant castable can withstand high temperatures and alkaline flue gas erosion to protect the equipment.
- In glass kilns, alkali-resistant castable can resist the erosion of alkaline components in the glass liquid, maintain the integrity of the kiln structure, and improve the quality and output of glass.
- In cement industry, alkali-resistant castable can be used for preheaters, decomposition furnaces, tertiary air ducts, grate coolers and other equipment.
