Blast Furnace Blow Pipe used high alumina high strength refractory castable are mainly by high bauxite as the matrix, the use of modern ultra-fine powder composite technology, adding high-performance dispersant, pure calcium aluminate cement as a binder, the use of forced homogenization process Of the water-based amorphous refractory castable. With high strength, alkali erosion, good wear resistance and other excellent performance, mainly for large and medium-sized new dry kiln kiln door cover, grate cooler and other parts.
