Corundum Brick is a kind of refractory product with corundum as the main crystal phase and contains over 90% aluminium oxide content. Corundum fire bricks have very high cold crushing strength that can reach up to 340MPa and high apparent initial softening temperature that is over 1700℃.
There are three purposes of fused cast azs block melting process: coordinate the melting of alumina and make it re-crystallized into corundum; make zirconia which is decomposed by zircon sand melted and re-crystallization to baddeleyite; Produce the molten liquid which has even chemical composition with less carbon content and containing the least bubbles, and the molten liquid has a certain
Chrome corundum brick is adopted corundum and fused chromium oxide as raw material, mixed with micro powder and other additive, after mixing, shaping, drying, sintering at high temperature shuttle kiln.
It has dense structure and no contamination to glass. It is the ideal refractory materials for channels, spouts and working ends of floating glass furnace. Alpha fused cast alumina block is an ideal product for the lower temperature zones of the glass melting furnaces due to its high density, superior corrosion resistance and low blister potential.
Zircon materials have been more widely used in the glass industry, metallurgical industry, cement industry, ceramics industry and refractory industry, due to high melting temperature, good chemical stability, good thermal shock, and good resistance to molten metals, slags or glass liquid. Zircon materials are mainly used in the melting zone
Therefore, zircon refractory also plays good performance on the application in furnace bottom of aluminium metallurgy. AZS zirconia-corundum refractory brick has become the necessary refractory material for the key position in the glass furnace with the development of glass industry, which can resist vitreous humour erosion strongly.
Apr 13, 2006 · This research was conducted to develop new formulations of AZS (alumina-zirconia-silica) refractories with different amounts of ZrO2 with the purpose of improving properties and the work conditions in the glass melting furnaces and, at the same time, lower the costs this type of refractories.

Corundum brick has a very good chemical stability. It has strong resistance for acidic or alkaline slag, metal and glass, etc. Corundum brick has the advantages of high density, low porosity, high bonding strength, high hardness, high soft, good wear resistance
Glass Fiber Furnace Zircon Corundum Brick, Alumina Refractory Bricks Introduction Zircon corundum brick is adopts alumina powder and zircon sand as raw material, after mixing, shaping, drying, sintering at high
Silica Refractory Brick is mainly used to lay coking chamber of coke oven and partition wall of combustor, kiln crown and wall of glass furnace and calcining kiln of silicate product. Use high dense silica fire brick to lay Large-scale coke oven, which can thin the wall of coking chamber and combustor to improve the production capacity.
Zircon brick ZS 64 made from stable zircon sand is a kind of great refractory brick with the zircon content over 64 %. It is acid refractory with the advantages of high mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquid.
High corundum content and high chemical purity are required for high conductivity, but porosity and glass content are also important for commercial high alumina refractory bricks, based on the observed discrepancy of conductivity between the bricks of 93 and 88 wt% Al/sub 2/O/sub 3/.
