喷砂用金刚砂磨料一级金刚砂人造磨料F150 F180 Brown fused alumina产品简介：

棕刚玉是铝矾土经过电熔后的人造磨料，它是一种主要成分为氧化铝的刚玉相非金属材料。棕刚玉大块的冶炼工艺分为倾倒炉和固定炉。破碎工艺分为对辊磨和巴马克球磨。分选工艺分为筛分和水洗溢流。筛分标准又分为F标标准和P标标准。棕刚玉的质量等级分为一级棕刚玉，二级棕刚玉，三级棕刚玉等等。因此，市场上的棕刚玉品质和价格相差很远。

一级棕刚玉的硬度和耐火性能是其中的***，通常用于喷砂研磨和制成磨具。棕刚玉的硬度接近白刚玉，比天然金刚砂高。棕刚玉的韧性比白刚玉好，体积密度高，自锐性磨削力略低，适合进行大规模的喷砂和快速研磨。棕刚玉适合的研磨对象为碳钢、铝合金、铁合金、各种非金属等。

Brown corundum is an artificial abrasive made from fused alumina, which is a non-metallic material with alumina as its main component. The smelting process of large brown corundum blocks is divided into pouring furnace and fixed furnace. The crushing process is divided into roller grinding and Bamac ball milling. The sorting process is divided into screening and water washing overflow. The screening standards are divided into F standard and P standard. The quality grades of brown corundum are divided into first grade brown corundum, second grade brown corundum, third grade brown corundum, and so on. Therefore, the quality and price of brown corundum on the market differ greatly.

The hardness and fire resistance of first-class brown corundum are among the best, and it is usually used for sandblasting, grinding, and making grinding tools. The hardness of brown corundum is close to that of white corundum and higher than that of natural diamond sand. Brown corundum has better toughness than white corundum, higher bulk density, and slightly lower self sharpening grinding force, making it suitable for large-scale sandblasting and rapid grinding. Brown corundum is suitable for grinding carbon steel, aluminum alloys, ferroalloys, various non-metallic materials, etc.
