AZS33 Fused cast refractories

AZS33 Fused cast refractories
  Fused cast refractories be used in glass furnace or frit furnace. Using zircon sand as raw material, after melting, cast in the mould, then curdle, keep warm, demould, grind, assembly, packing and delivery. Classified by casting process, there are NC(Normal Casting), VF(Void Free),  different cast process are suitable for different part of glass furnace.  
  AZS33 fused 
cast refractories is suitable for superstructure of melting pool, sidewall and floor blocks of work pool, forehearth etc.  
  Using our patented technology, our fused cast AZS blocks' service life longer 30% than the same industry.
