The composition and characteristics of brown alumina
The brown corundum grinding stone is mainly made of brown corundum sand and clay after high temperature sintering. Because the particle size of the grinding sand is 120 and has strong grinding ability, the grinding stone of this kind of raw material is mainly suitable for rough polishing. It can quickly remove burrs, fronts and scales on the workpiece surface. The shapes of the brown corundum grinding stones produced by our company include balls, yuan columns, oblique yuan columns, regular triangles, oblique triangles, etc., which can be produced from 2mm to 50mm in size. Customers can choose the suitable grinding stone according to the shape and size of the workpiece, and then reach the perfect role of ambition. Special shapes and specifications can be made according to requirements.
Characteristics of Brown Corundum Brown corundum has the characteristics of high purity, good crystallization, strong fluidity, low linear expansion coefficient, and corrosion resistance. It has been verified by dozens of refractory production enterprises that this product has the characteristics of no explosion, no chalking and no cracking in the application process. In particular, its cost performance is much higher than that of traditional brown corundum, making it the best aggregate and filler for brown corundum refractories.
