Description
White fused alumina(WFA, also named sintered tabula alumina) with industrial alumina powder as raw material, It is made by melting over 2000 ℃ in arc and then cooling, after smashing plastic, magnetic separation to iron, screen is divided into a variety of particle size, the high density, high hardness, particle into Angle shape .
WFA is the main raw material for producing advanced unshaped and shaped refractory materials，the main brands are WFA 5-8/3-6/1-3/6-14/0-1/325 mesh and so on.
WFA is the main raw material for producing advanced unshaped and shaped refractory materials, widely used in steel, cement, ceramics, petrochemical and other industries, such as large ladle castable, medium and high grade iron hook castable, gunning prefabricated parts；corundum brick and mullite hard jade sagger, refined corundum porous plug brick, integral spray gun and composite nozzle, high-temperature industrial kiln furnace lining materials and other corundum products.
