The corundum Production and frit structure

Production:
White fused alumina smelting the frit law and dumping and French.
White corundum and corundum smelting different points: the production of white fused alumina, construction of lining materials are generally white corundum sand or aluminum oxide powder. Received a package sub-pin linerless definitely connected with package and there are lining then package the. The linerless access package to be forced water cooling, backed commonly used graphite or white fused alumina refractory products for the bag lining.
??The frit production of white fused alumina, the lining requires good insulation properties, and good air permeability, furnace of a lining and lining two. There lining generally require the use of sintered products, linerless thermal loss usually accounts for more than 24% of the energy consumption of the products lining heat loss accounted for only about 4%.
Structure:
Superstructure: The superstructure is a solid, porous lamellae, the lower part is often the folder fine crystals of how cylindrical holes.
Stoves: a solid structure, porosity, the central part more developed, large tracts of glassy, ??porous, and the different shapes of the crystals, white in color, mostly gray and dark gray. In the lower part: coarse crystalline, compact structure, color white, crystalline gloss best.
Edge: crystal, but more loose, mostly columnar or granular crystal block, and has a hole, the Ministry of sidelined with a microcrystalline corundum.
