镀铱棕刚玉磨料Ceramic coated Brown Fused Alumina
镀铱棕刚玉分为中温煅烧棕刚玉镀铱和高温煅烧棕刚玉镀铱。他们都是以棕刚玉倾倒炉砂为原材料进行加工的。煅烧工艺可以减少棕刚玉磨料的杂质含量和粉尘，也可以将破碎过程中棕刚玉砂产生的裂缝进行高温整形。镀铱工艺可以提高磨料颗粒的韧性、亲水性和颗粒表面粗糙度，增加结合剂对磨料颗粒的把持力，制成砂轮产品后可以提高切割效率和适用时长。
Ceramic coated calcined brown aluminum oxide and Ceramic coated blue fired aluminum oxide are both Ceramic coated Brown fused alumina abrasive grains. They are processed from tilting furnace brown aluminum oxide as raw material. The calcination process can reduce the impurity content and dust of brown aluminum oxide. It can also perform high-temperature shaping on the cracks generated during the crushing process of BFA. The ceramic coating process can improve the toughness, hydrophilicity, and surface roughness of abrasive particles, increase the holding force of binders on abrasive particles. As a result, it improves cutting efficiency and applicability time after making grinding wheel products.
