The filter plate is made for Brown fused alumina.

It is bauxite, coke, anthracite as main raw materials, in the Canon of high temperature smelting electric arc

furnace, the main chemical composition of AL2O3, TiO2 loop contains a small amount of SiO2 and Fe2O3,

microhardness HV1800-2200, high toughness than SiC, use it made of abrasive, suitable for grinding the high

tensile metals, such as all kinds of steel, malleable cast iron, hard bronze, etc., also can make advanced

refractories. Brown fused alumina with high quality abrasive grade bauxite as raw material, the arc integrated

by more than 2000 degrees high temperature melting, shattered by the mill Plastic, magnetic separation to iron,

screen is divided into A variety of particle size, dense texture, high hardness, particle formed globular, suitable

for manufacturing ceramic porcelain, resin high consolidation abrasive and grinding, polishing, sandblasting,

precision casting, etc., can also be used for manufacturing high-grade refractory materials, code-named "A"

international general standards, national standards are consistent, most for export, supply domestic users alsohave A certain amount.
