Brown Fused Alumina is produced by the smelting of Calcined Bauxite in an electric arc furnace at temperatures greater than 2000°C. A slow solidification process follows the fusion, to yield blocky crystals.Strict control over Titania levels during the fusion process ensures optimum toughness of the grains.Corundum refractory brick used in normal temperature compressive strength is very high (up to 340MPa), high load softening start temperature (higher than 1700 DEG C), excellent chemical stability, resistance to acid or alkaline slag, metal and glass liquid had strong. Mainly used in blast furnace and the hot blast furnace, ladle furnace refining furnace, water heater, sliding glass furnace as well as the petroleum chemical industrial furnace.
