Fused Cast AZS are the most widely used materials in glass melting furnaces, frit kilns and occasionally some foundry plants(skid rails of reheating furnace). They can be classified by their zirconia content, which basically defines their corrosion resistance, into 3 families: AZS 33, AZS36 &AZS 41 (Equal to ER 1681, ER 1685, ER 1711 or Monofrax CS-3, CS-4, CS-5 in quality)
