2. Applications:
♦Brown fused alumina is high temperature, corrosion resistance, high strength properties, it poured with steel sliding gate, smelting rare metals, special alloys,
ceramics, iron-smelting furnace of the lining (walls and tubes); physical and chemical containers, spark plugs, heat-resistant anti-oxidation coating.
♦Brown Corundum heat preservation material, such as lightweight corundum brick, corundum hollow ball and fiber products,
widely used in a variety of high-temperature kiln furnace walls and roof, both high temperature-resistance and heat-preservation.
♦Mainly used for abrasion and high temperature resistant, inoxidizable aggregate and filling of shaped and monolithic refractory in steel metallurgy,
various industrial stoves, electric furnace etc.
