The products are produced by corundum and chromium oxide as main materials, formed from casting, after being treated under high temperature, it has high hot strength and good wear resistance, suitable for making the slide rail part of heating furnace. For structures constructed with fused cast AZS and silica brick (such as the front wall of the feeder pool),each material should have its own structure, because they have different volume changes at high temperature. For the superstructure that is less than 8m, there is no need to leave expansion joints. For the superstructure ceramic fiber felt that is longer than 8m, it is recommended to divide it into several parts by expansion joints(4-6mm). There are masonry joints between the sidewall block and the bottom block. When the refractory materials are heated, 4-5mm volume expansion per meter will be expanded into the masonry joints. Fused cast AZS block has a higher thermal conductivity. When used in the sidewall, it parts near the liquid ladle castable level require bigger cooling air flow. Based on the campaign life of the glass furnace, the indicators of the furnace operation and the physical and chemical properties and performance of fused cast AZS block, some reasonable suggestions high insulating brick are made on the proper use of the fused cast AZS. Fused cast AZS is characterized with stable and dense structure and good corrosion resistance to glass. During 900-1200℃, it will have a abnormal volume expansion due to its crystal phase transition.
