What is 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 manufacturers that the product has the characteristics of non-explosion, non-powdering, and non-cracking during 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-based refractories.
Brown fused alumina wholesale
Product particle size is produced in accordance with international standards and national standards, and can be processed according to user requirements. The general particle size number is F4~F320, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact resistant. Because it is processed and broken by a self-grinding machine, the particles are mostly spherical particles. Rongxing brand brown corundum has high purity, dense texture, high bulk density, strong self-sharpening, good toughness, and magnetic content. Very low characteristics, the abrasive tools made of it have sharp grinding, low heat generation rate, high grinding ratio, and less adhesion during use; the sintered abrasive tools made have a dark blue color after firing, and no net-like cracks , No rust spots, suitable for manufacturing ceramic, resin high-consolidation abrasive tools, grinding, polishing, etc.
The production of brown corundum stipulates the technical conditions of brown corundum in order to achieve high final product quality, which requires an understanding of the direction of use of the product and the production process of brown corundum. The grinding and refractory properties of brown corundum are affected by its basic chemical composition, the content of impurities, and the distribution of impurities in its crystal structure. Brown fused alumina is made from calcined bauxite through a reduction process in an electric arc furnace. Most of the brown fused alumina produced around the world is of high quality and can meet the needs of most customers. If the end use of brown corundum has special requirements for its quality, the supplier and customer are obliged to fully negotiate all requirements.
