Silica mortar for hot blast stove is an important part of refractory mortar which uses silica sand as the main raw material. The binder may be a soft clay or chemical binder.



  1. High adhesive strength.
  2. High refractoriness.
  3. Excellent refractoriness under load.
  4. Good installation performance.



Silica mortar for hot blast stove is mainly used for laying and repair of coke oven, hot blast stove, glass melting furnace, melting furnace and other masonry of high quality silica bricks industrial furnaces.
