Brown aluminium oxide

With bauxite, carbon material, iron filings as raw materials, Brown Fused Alumina is restored and obtained through the melting of the brown the brownartificial corundumin the furnace above 2200 ℃, and made of a variety of particle sizes products by purifying, crystallization, sorting, crushing, ic separation and screening methods. With its dense texture, high hardness and the formation of spherical particles, it is suitable for the manufacture of ceramics and resin, as well as the high-Bonded Abrasives grinding, polishing, sand blasting, precision casting and so on, also can be used to manufacture high-grade refractory material.
Brown Fused Alumina has high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant and other characteristics. Dozens of refractory manufacturers have proved in practice that the product has not detonate, non-powder, non-cracking characteristics in the application process.
Particle size is in ordance with international standards and can be processed as requirements. Universal size: No. F4 ~ F320, its chemical composition varies depending on grain size. Its prominent feature is the small crystal size, impact resistance and spherical particles. This product has high purity, dense texture, large bulk density, strong self-sharpening, good toughness, low level ic material content and other characteristics.








棕刚玉
棕刚玉是以铝钒土、焦碳(无烟碳)为主要原料,在电弧炉内经高温治炼而成,主要化学成分为Al2O3,TiO2还有少量的SiO2和Fe2O3等。显微硬度HV1800-2200,韧性比SiC高,它具有硬度高、韧性大、颗粒锋锐、磨削力强、耐高温、效率高等特点。用它制成的磨具,适于磨削抗张力强度较高的金属,可切割,如各种通用钢材,碳素钢,一般合金,可锻青铜,硬青铜等,也可作为高级耐火材料,广泛用于钢铁、化工用其他行业。

棕刚玉砂轮是磨削加工中最主要的磨具之一。白刚玉砂轮是在磨料中加入结合剂,经压坯、干燥和焙烧而制成的多孔体。由于磨料、结合剂及制造工艺不同,砂轮的特性差别很大,因此对磨削的加工质量、生产率和经济性有着重要影响。砂轮的特性主要是由磨料、力度、结合剂、硬度、组织、形状和尺寸等因素决定 砂轮种类繁多。 按所用磨料可分为普通磨料(刚玉和碳化硅等)砂轮。 按形状可分为平形砂轮、斜边砂轮、筒形砂轮、杯形砂轮、碟形砂轮等;按结合剂可分为陶瓷砂轮、树脂砂轮、橡胶砂轮、金属砂轮等。砂轮的特性参数主要有磨料、粒度、硬度、结合剂、形状、尺寸等。 由于砂轮通常在高速下工作,因而使用前应进行回转试验(保证砂轮在最高工作转速下,不会破裂)和静平衡试验(防止工作时引起机床振动)。砂轮在工作一段时间后,应进行修整以恢复磨削性能和正确的几何形状。
