Ruby Fused Alumina 80#-180#高铬铬刚玉研磨砂技术参数表

Ruby Fused Alumina 80#-180#高铬铬刚玉研磨砂

Ruby Fused Alumina 80#-180#高铬铬刚玉研磨砂的颜色比中铬铬刚玉的粉色更深。冶炼过程中添加的氧化铬含量1-2%，其自锐性比棕刚玉高，韧性和耐磨性能比白刚玉高。氧化铬的添加提高了刚玉的晶体的抗冲击能力和机械强度，特别适合生产磨床砂轮、齿轮磨砂轮。针对淬火钢高速钢等材质，其研磨效率比普通砂轮提高1-2倍，寿命提高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.

由于铬刚玉具有更好的韧性，用于生产磨具制品时，能显著提升磨具的使用寿命，锋利度，磨削力等性能，也可以防止磨削过程对工件的损伤。具体应用场景如下：

树脂砂轮如超薄切割片，打磨片，砂轮有很好的耐用性和锋利度。
陶瓷砂轮如机床用磨轮，杯型砂轮，碗型砂轮，橡胶砂轮，磨头等。
涂附磨具如抛光轮，砂布砂纸，美甲条等。
对喷砂要求比较高的喷砂操作
精密仪表器件的磨削
碳钢、高速钢、合金钢的研磨抛光
