白剛玉F230即電熔氧化鋁W63,是磨具行業(yè)例如油石、拋光輪等產(chǎn)品常用的磨料。因其耐磨性好,自銳性好,硬度高等優(yōu)點(diǎn),廣泛用于研磨制品的原材料。電熔氧化鋁是將純度99%含量的工業(yè)氧化鋁粉在電弧爐里經(jīng)2050度高溫熔融冶煉結(jié)晶而來,因此電熔氧化鋁又被稱為電熔剛玉。電熔氧化鋁純度高、自銳性好、耐酸堿腐蝕、耐高溫、熱態(tài) 性能穩(wěn)定它硬度略高于棕剛玉,韌性稍低,切削力強(qiáng)。
White alox F230, also known as fused alumina W63, is a commonly used abrasive in the abrasive industry, such as oilstones, polishing wheels, and other products. Due to its good wear resistance, self sharpening, and high hardness, it is widely used as a raw material for grinding products. White electro fused aluminum oxide is obtained by melting and crystallizing industrial alumina powder with a purity of 99% in an electric arc furnace at a high temperature of 2050 degrees Celsius, hence it is also known as electrically fused alumina. Electromelted alumina has high purity, good self sharpening, acid and alkali corrosion resistance, high temperature resistance, and stable thermal performance. Its hardness is slightly higher than that of brown alumina, and its toughness is slightly lower, with strong cutting force.
1. 生產(chǎn)磨具制品用的白剛玉磨料選用純度固定爐白剛玉塊,硬度、堆積密度、韌性優(yōu)于傾倒?fàn)t白剛玉,能提升砂輪的耐磨性,磨削力。
2. 白剛玉的自銳性強(qiáng),在磨削過程中可不斷產(chǎn)生棱角進(jìn)行研磨,生產(chǎn)出來的磨具制品鋒利,不會燒傷工件。
3. 磨具生產(chǎn)用的白剛玉堆積密度高,單位體積內(nèi)可放入更多的磨粒,磨削或切割過程中有更多的磨料參與工作,可以提高產(chǎn)品的使用壽命。
4. 電熔白剛玉砂的粒度均勻,對粒徑范圍的控制嚴(yán)格;白剛玉微粉經(jīng)過酸洗水分工藝生產(chǎn),無大顆粒,兼顧了表面粗糙度和研磨效率。
5. 磨具生產(chǎn)用的白剛玉顏色白度高,雜質(zhì)少,可添加各種染料制成彩色的砂輪。
6. 白剛玉的鈉含量低,阿爾法轉(zhuǎn)化率高,硬度高。白剛玉的鐵含量可以忽略不計(jì),因而不會對磨削工件造成污染或燒傷。制成的砂輪可用于醫(yī)療、食品工業(yè)、航空航天、半導(dǎo)體等領(lǐng)域。
