耐火棕剛玉爐料
耐火棕剛玉爐料Description of brown fused alumina:
耐火棕剛玉爐料是以鋁礬土、無煙煤為主要原料，在2000度以上電弧爐內(nèi)經(jīng)高溫冶煉而成，用它制成的磨具，適于磨削抗張較高（鋼材、可鍛鑄鐵、硬青銅等）的金屬，適用于制造陶瓷、樹脂高固結(jié)磨具以及研磨、拋光、噴砂、精密鑄造等，也可制造高級耐火材料。棕剛玉具有純度高，結(jié)晶好，流動性強，線膨脹系數(shù)低，耐腐蝕、耐高溫、高強度等特點。
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 brown fused alumina are suitable for metal with high tensile(like: steel, malleable iron, bronze etc). Suitable for product high consolidation abrasive, and suitable for grinding, polishing, blasting, precision casting etc. 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.
