Blast Furnace Blow Pipe used high alumina high strength refractory castable
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.
Features and Advantages of blast furnace blow pipe used high alumina high strength castable:
1. High refractoriness, High refractoriness under load.
