Ruby Fused Alumina 80#-180#高鉻鉻剛玉研磨砂


       Ruby Fused Alumina 80#-180#高鉻鉻剛玉研磨砂的顏色比中鉻鉻剛玉的粉色更深。冶煉過(guò)程中添加的氧化鉻含量1-2%,其自銳性比棕剛玉高,韌性和耐磨性能比白剛玉高。氧化鉻的添加提高了剛玉的晶體的抗沖擊能力和機(jī)械強(qiáng)度,特別適合生產(chǎn)磨床砂輪、齒輪磨砂輪。針對(duì)淬火鋼高速鋼等材質(zhì),其研磨效率比普通砂輪提高1-2倍,壽命提高4倍,大大提高了加工效率。

The color of Ruby fused alumina is darker than the pink fused alumina grain. The chromium oxide content added during the smelting process is 1-2%, and its self sharpening property is higher than that of brown fused alumina, and its toughness and wear resistance are higher than that of white fused alumina. The addition of chromium oxide improves the impact resistance and mechanical strength of corundum crystals, making it particularly suitable for producing grinding wheels and gear grinding wheels. For materials such as quenched steel and high-speed steel, the grinding efficiency is 1-2 times higher than that of ordinary grinding wheels, and the service life is increased by 4 times, greatly improving the processing efficiency.

由于鉻剛玉具有更好的韌性,用于生產(chǎn)磨具制品時(shí),能顯著提升磨具的使用壽命,鋒利度,磨削力等性能,也可以防止磨削過(guò)程對(duì)工件的損傷。具體應(yīng)用場(chǎng)景如下:

  1. 樹(shù)脂砂輪如超薄切割片,打磨片,砂輪有很好的耐用性和鋒利度。
  2. 陶瓷砂輪如機(jī)床用磨輪,杯型砂輪,碗型砂輪,橡膠砂輪,磨頭等。
  3. 涂附磨具如拋光輪,砂布砂紙,美甲條等。
  4. 對(duì)噴砂要求比較高的噴砂操作
  5. 精密儀表器件的磨削
  6. 碳鋼、高速鋼、合金鋼的研磨拋光
