Product Description:

PN series of alkali-resistant castables are made from high siliceous materials. At high temperatures, alumina-silicate linings react with alkali compounds to form high viscosity liquid layer, which prevents erosion of alkali gas and enhances the alkali resistance of the lining. This series also features anti-coating formation performance. They can be well-applied for the linings of the preheater system and cooling section of grate coolers.
