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。白刚玉段砂、粒度砂、细粉、微粉在耐火材料、磨料磨具等不同行业具有广泛的用途。
White fused alumina is made of quality alumina powder by smelting at 2050 ℃, characterized by high purity, good self-sharpening, less thermal diffusivity in grinding, strong acid-alkali resistance, excellent high-temperature stability, low porosity, etc. White fused alumina products including section sand, grain-size sand; fine powder and micro powder are widely used in refractories, abrasives and other different industries.
段砂、细粉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;在定型制品中,主要用在刚玉砖、刚玉莫来石质匣钵、炼钢连铸三大件、超高温工业窖炉内衬等刚玉制品。
Section sand and fine powder are the main raw materials for the mid-and-top-grade unshaped and shaped refractories, that are widely used in unshaped refractory products like ladle castable, iron runner, gun-mix refractory, etc. In the production of shaped products, they are mainly used for making corundum products like corundum brick, corundum mullite sagger, three major steel-making and continuous-casting pieces and ultra-temperature industrial furnace liner.
粒度砂主要用作磨料磨具,在磨料行业中,可用在各式喷砂和研磨作业;电视屏幕制程中喷砂;齿模之清洁喷砂;精密铸造用型砂;在磨具中经常用作陶瓷、树脂固结磨具和涂附磨具的原料。
Grain-size sand is mainly used as abrasives, a perfect choose for various sand blasting and grinding operations in the abrasive industry, such as the sand blasting in TV screen processing and tooth mold cleaning. Besides, it also can be used as the foundry sand in precision casting and the raw materials of ceramic and resin bonded abrasives as well as coated abrasives.
