AC- 36S (Fused cast AZS36S block with Low Silicon Low Sodium)


With lower SiO2 and Na2O content, AC-36S bears less vitreous phase, higher exudation temperature

Category:

Fused zirconium corundum


With lower SiO2 and Na2O content, AC-36S bears less vitreous phase, higher exudation temperature, better high-temperature stability and superior corrosion resistance to molten glass, and thusly is the most ideal material to realize glass furnace’s overall insulation, energy-efficiency and longevity.

Casting Technology 

Void Free Cast

Casting is performed with a large header in which most of the voids are concentrated.The header is subsequently cut off after cooling.The resultant block is compact and substantially void-free.AC-41 and AC-M are preferably in WS casting.
