【棕刚玉简介】

      棕刚玉，俗名又称金刚砂，是用矾土、碳素材料、铁屑三种原料在电炉中经过融化还原而制得的棕褐色人造刚玉，故为此名。棕刚玉主要化学成份是AL2O3，其含量在94.5%-97%，另含有少量的Fe，Si，Ti等。
    棕刚玉是以铝矾土、焦碳（无烟煤）为主要原料，在电弧炉内经高温冶炼而成，用它制成的磨具，适于磨削抗张较高的金属，如各种通用钢材、可锻铸铁、硬青铜等，也可制造高级耐火材料。棕刚玉具有纯度高，结晶好，流动性强，线膨胀系数低，耐腐蚀的特点。经数十家耐火生产企业实践验证，该产品在应用过程中具有不起爆、不粉化、不开裂的特点。尤其是其远高于传统棕刚玉的性价比，更使之成为棕刚玉质耐火材料的较佳骨料和填充料。
    棕刚玉主成分是氧化铝，分等级也就用铝含量来区分， 铝含量越低也就硬度越低了。
    产品粒度按国际标准以及各国标准生产，可按用户要求粒度进行加工。通用粒度号为F4~F320，其化学成份视粒度大小而不同。突出的特点是晶体尺寸小耐冲击，因用自磨机 加工破碎，颗粒多为球状颗粒，表面干洁，易于结合剂结合。

【 Brown fused alumina introduction 】
Brown fused alumina, local name, also known as carborundum, is made of alumina, carbon materials, scrap iron three kinds of raw materials in electric furnace melting reduction and made of brown alundum, reason for this name.Brown fused alumina is mainly chemical composition is AL2O3, and its content from 94.5% to 94.5%, the other contains a small amount of Fe, Si, Ti, etc.
Brown fused alumina is bauxite, coke, anthracite as main raw materials, in the Canon of high temperature smelting electric arc furnace and become, 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 purity, good crystallization, strong liquidity, low linear expansion coefficient, the characteristics of corrosion resistance.The dozens of refractory production enterprises have proved that the product in the application process has not initiation, not pulverization, not cracking characteristics.Especially its far higher than the traditional brown corundum price, more make it become the best in the brown just the quality of the jade of refractory aggregate and filling material.
Corundum principal component is the alumina, aluminum content hierarchical is used to distinguish, the lower the aluminum content is, the lower the hardness.
Product size according to the international standard and national standard production, granularity processing according to user requirement.Gm grain sizes of the F4 ~ F320, its chemical composition depending on the size of the particle size.Outstanding characteristic is little impact resistance, crystal size in use since the mill processing, particles are spherical particles, the surface dry clean, easy to bond.
【 Brown fused alumina characteristics 】
Brown fused alumina with high purity, good crystallization, strong liquidity, low linear expansion coefficient, the characteristics of corrosion resistance.The product in the application process has not initiation, not pulverization, not cracking characteristics.Especially the far higher than that of the traditional corundum price, more make it become the best in the brown just the quality of the jade of refractory aggregate and filling material. 
Product size according to the international standard and national standard production, granularity processing according to user requirement.Gm grain sizes for P4 ~ FP320, its chemical composition depending on the size of the particle size.Outstanding characteristic is little impact resistance, crystal size in use since the mill processing, particles are spherical particles, HongCheng brand brown fused alumina with high purity, dense texture, bulk density is big, the sharpness is strong, good toughness and the characteristics of the content, low magnetic material, made of its sharp abrasive grinding, low heating rate, high grinding ratio, and when using cleave less;Made of sintered abrasive has burnt after the color is dark blue, not reticulate crack, no rusty spot, the characteristics of high consolidation is suitable for making ceramic, resin abrasive and grinding, polishing, etc. 
Brown fused alumina because of its high hardness, good toughness and multi-purpose for grinding materials, is one of the most basic of abrasive.

【 Brown fused alumina USES 】
Brown fused alumina called industrial teeth: mainly used in refractory materials, grinding wheel, sand blasting.
1, sand blasting, corundum, sandblasting abrasive hardness is moderate, high packing density, no free silica, than major, good toughness and is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, washing jeans precision molds, and other fields;
2, free abrasive, abrasive abrasive, applied to the tube, optical glass, monocrystalline silicon, glass, crystal glass lens, clock, jade in areas such as free grinding, grinding is adopted widely in the domestic advanced materials;
