棕刚玉W28抛光粉 F#400目棕刚玉微粉
W28棕刚玉F#400目棕刚玉微粉是以铝矾土、焦碳煤)为主要原料,在电弧炉内经高温冶炼而成。主要化学成份为AL2O3、TiO2还含有少量的Sio2和Fe2O3等,显微硬度HV1800-2200、韧性比SiC高,用它制成的磨具,适于磨削张强度较高的金属,如各种通用钢材、可锻铁、硬青铜等。也可制造耐火材料。
Brown fused alumina iade of bauxite, anthracite coal, andelted in electric-arc furnace of high temperature more than 2000 degrees. Abrasives toolade by Haixu/Sicheng brown fused alumina are suitable for metal withhigh tensile(like: steel, malleable iron, bronze etc). Suitable for product high colidation abrasive, and suitable for grinding, polishinasting, precision casting etc. Haixu/Sicheng brown fused alumina is also used for refractory material. Brown fused alumina with characteristics like: high purity, good crystalline liquidity, low coefficief linear expansion, corrosion resistance, high temperature, high strength.
W28/F#400目棕刚玉微是以铝矾土煤、铁屑作为主要原料,在电弧炉内经高温炼制而成,呈棕褐色,韧性好,显微硬度1800-2200kg/mm2,体积密度3.85g/cm3,耐高温,耐火度高达1850℃,由于它具有耐高温,强度高耐侵蚀损等优良性能,所以在耐火材料和磨料磨具行业被广泛使用,可做耐火材料和磨料。 |
