棕刚玉是由铝矾土经电弧炉冶炼而成,呈棕褐色,产品硬度高、韧性大,用其制成的磨具适用于磨削碳素钢、一般合金钢、可锻铸铁、硬青铜等,并广泛应用于刚玉铁沟浇铸料,捣打料等耐火制品。
It is a kind of regular Brown Aluminum Oxide abrasive grains, the shape of the grain is blocky and edge sharp with the high loose bulk density. To get the kind of grains, we specially process the ingots, separate the magnetic material, and sieve the grains carefully to get a complete range of grit sizes.
As an abrasive, It is mainly used in making vitrified bonded grinding wheels. As loose grains, it is widely used for pressure blasting, surface finish and other general industrial applications.
