低钠白刚玉磨料 F20-F220 Na2O<0.1%

白刚玉是以优质氧化铝粉为原料，在2050℃高温下熔炼而成，它具有纯度高、自锐性好、磨削时发热量小、耐酸碱、高温稳定性好、气孔率低等优点。

电熔白刚玉是生产中高档不定型和定型耐火材料的主要原料，常用于钢包浇注料、铁沟料、耐火喷补料等不定型耐火制品；在定型耐材中，它主要用在刚玉砖、刚玉莫来石质匣钵、精炼用刚玉多孔塞砖、整体喷枪、炼钢连铸三大件、超高温工业窑炉内衬等刚玉制品。它又是磨料磨具行业优质原料，主要用在砂轮磨具、抛光研磨行业，在军工、造船、玻璃、航空、航天、光学仪器、核能等行业有广泛的前途。

White fused alumina is made from excellent industrial alumina and melted in arc furnaces at high temperature of 2050℃.It is featured by high purity, good self-sharpening, low grinding heat output, acid-alkali and corrosion resistance, good stability at high temperature, and low porosity, etc.

As the main raw material for producing middle/high-class monolithic refractories or formed refractory products, white fused corundum is used primarily for ladle castable, iron runner castable gunning refractory or other monolithic refractory products. As for formed refractories, it’s chiefly used in producing corundum bricks, corundum-mullite saggers, refining-used corundum porous plug bricks, integral blowing lance, three-piece for steel making con-casting production, ultra-high temperature industrial furnace lining, and other corundum products. It’s also the high-quality raw material in abrasives industries, mainly used for producing grinding wheel, grinding and polishing tools, as well as the most promising material with bound less prospects used in military, ship building, glass making, aerospace, optical-instrument-manufacturing, nuclear power plants construction and other industries.
