Corundum, is bauxite, carbon materials, iron filings in the three kinds of raw material through the melting furnace in the reduction in the system tan artificial corundum, so that end name. The main chemical composition is corundum AL2O3, its content of 94.5% -97%, and the other containing a smallCorundum is bauxite, coke Fused zirconia mullite (anthracite) as the main raw material in electric arc furnace at high temperature smelting, made ??by grinding it suitable for grinding high tensile metal, such as a variety of common steel , malleable iron and hard bronze, etc., can also create advanced refractories. Corundum with high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant characteristics. Dozens of refractory producers proven that the product has not detonate in the application White fused aluminum oxide process, not powder, not crack characteristics. In particular, its cost is much higher than conventional corundum, but making the best of corundum refractory aggregate and filler. amount of Fe, Si, Ti and the like.Main component is alumina corundum, graded to distinguish it from aluminum content, the lower aluminum content will lower the hardness of it.
Product size in accordance with international standards and national standards cubic boron nitride of production, processing granularity according to user requirements. Universal size No. F4 ~ F320, its chemical composition varies depending on grain size. Prominent feature is the small crystal size, impact resistance and self-processing mill with broken particles are mostly spherical particles, the surface of the dry-cleaning, easy binding agent.
