The Process Theory and Application of Fused Cast Alumina Block
Fused corundum brick is the oxidation of bauxite and other raw material product cooling and solidification of melt in the furnace, it has the advantages of simple process, short process, low product cost. Because of the different varieties of fused alumina, can add different reductant in the process of the welding torch. Approaching corundum melting point (2100 ℃) of the structure of the alumina melt is similar to corundum brick, when this kind of melt on cooling, crystallization becomes corundum brick. When corundum brick melt, melt molar volume increased 23.5%, the heat of fusion is 109.2 KJ/mol, and with the increase of melt temperature, reducing its density.

The Applications of Refractories in Different Parts of Glass Furnaces
The maximum temperature of the melting zone in the glass furnace is 1570-1610℃. The safety limit usually depends on the glass composition and the softening point of silica brick crown. The silica bricks begin to soften and melt in 1620℃. The reason why the crown is built with silica bricks instead of other refractory materials with higher refractoriness is that they have high strength at high temperature and their ablated materials are also compatible with glass, while other refractory materials may produce insoluble stones and other inclusions.
