棕剛玉W28拋光粉 F#400目棕剛玉微粉
W28棕剛玉F#400目棕剛玉微粉是以鋁礬土、焦碳(無煙煤)為主要原料,在電弧爐內經(jīng)高溫冶煉而成。主要化學成份為AL2O3、TiO2還含有少量的Sio2和Fe2O3等,顯微硬度HV1800-2200、韌性比SiC高,用它制成的磨具,適于磨削抗張強度較高的金屬,如各種通用鋼材、可鍛鐵、硬青銅等。也可制造耐火材料。
Brown fused alumina is made of bauxite, anthracite coal, and smelted in electric-arc furnace of high temperature more than 2000 degrees. Abrasives tools made by Haixu/Sicheng brown fused alumina are suitable for metal withhigh tensile(like: steel, malleable iron, bronze etc). Suitable for product high consolidation abrasive, and suitable for grinding, polishing, blasting, 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 coefficient of linear expansion, corrosion resistance, high temperature, high strength.
W28/F#400目棕剛玉微是以鋁礬土、無煙煤、鐵屑作為主要原料,在電弧爐內經(jīng)高溫煉制而成,呈棕褐色,韌性好,顯微硬度1800-2200kg/mm2,體積密度3.85g/cm3,耐高溫,耐火度高達1850℃,由于它具有耐高溫,強度高,抗氧化,耐侵蝕,耐磨損等優(yōu)良性能,所以在耐火材料和磨料磨具行業(yè)被廣泛使用,可做耐火材料和磨料。 | |
