fused cast AZS AC-36 is an AZS type fused cast refractory material with about 36% zirconium-dioxide content,with less vitreous phase. which further improve the corrosion resistance and reduce the petential defects in glass. it can provide improved service over fused cast AZS AC-33 but are more economical than fused cast AZS AC-41. we recommends to apply the AZS AC-36 blocks for the parts of glass melting furnaces where glass flow is faster and temperature is higher,such as sidewalls,bottom paving,superstructures,feeder channels,working ends.
