棕剛玉16# Brown Fused Alumina從高品位的煅燒鋁礬土冶煉而來(lái)。在國(guó)標(biāo)標(biāo)準(zhǔn)中，只對(duì)一級(jí)棕剛玉的技術(shù)標(biāo)準(zhǔn)進(jìn)行了要求。一級(jí)次、二級(jí)、三級(jí)棕剛玉并沒(méi)有特定的規(guī)范。一級(jí)棕剛玉16#具有良好的研磨硬度和韌性，不僅適合金屬、碳鋼、不銹鋼的研磨，也可以作為耐磨骨料添加于地坪或用于耐火骨料。
Brown Fused Alumina 16 # is smelted from high-grade calcined bauxite. In the GB/ISO standard, only the technical standard for A grade Brown Fused Alumina is required. There are no specific specifications for B grade,C grade and lower quality brown one. A grade brown fused alumina 16 # has good grinding hardness and toughness, which is not only suitable for grinding metals, carbon steel, and stainless steel, but can also be added as wear-resistant aggregates to floors or used as refractory aggregates.
