Product Description
The The re-sintered fused zirconium mullite brick is formed by high-pressure forming and high-temperature sintering of Australian zircon sand, fused mullite, fused white corundum, composite ultrafine powder and special admixture. The glass furnace kiln, the melting pool, the upper structure of the working pool and the feeding channel have the characteristics of high temperature resistance, erosion resistance, slag resistance and glass corrosion, thermal shock stability and high temperature creep resistance.The zirconia corundum AZS series refractory products are processed by melted, crystallized, cast, insulated etc. The main raw material are industrial alumina, zirconia and desiliconized zirconium.Features For AZS Brick: 1. Raw material is corundum and baddeleyite eutecticum,high compression strength2.Top high-temperature capablility,excellent thermal stability.3.Strong resistant erosion stability to the glass liquid Process For Corundum Fire Brick : Made of the zirconite (Industry zirconia ) and industry alumina as the mainly mixed raw material, melting in the electric furnace, casting, annealing, machining, then finished.Chemical Composition % | AZS-33 | AZS-36 | AZS-41 |
