Brown fused alumina F24-F46 grit for abrasive wheels 棕色氧化鋁砂
Brown fused alumina F24-F46 grit for abrasive wheels 氧化鋁含量不低于95%，韌性好，顆?？箾_擊能力強(qiáng)，堆積密度高。用它制成的砂輪適合切割碳鋼、鑄鐵、鑄鋼等材料。除此以外，它還可以與其他更高端的磨料混合制成各種陶瓷結(jié)合劑砂輪、樹脂結(jié)合劑磨輪等產(chǎn)品。廣泛應(yīng)用于金屬加工、鐵路修整、表面處理等領(lǐng)域。Brown fused alumina F24-F46 grit for cutting disc has an alumina content of not less than 95%, good toughness, strong particle impact resistance, and high packing density. It has better hardness and durability than fixed furnace brown fused alumina. The grinding wheel made from it is suitable for cutting materials such as carbon steel, cast iron, and cast steel. In addition, it can also be mixed with other higher end abrasives to produce various ceramic bond grinding wheels, resin bond grinding wheels, and other products. Widely used in fields such as metal processing, railway finishing, surface treatment, etc.
Brown fused alumina F24-F46 grit for abrasive wheels 棕色氧化鋁砂的特點(diǎn)：
1. 氧化鋁含量高，硅、鐵等雜質(zhì)含量低，磁性物含量低，鈦含量適中。2. 冶煉更充分，致密性高，晶體尺寸比固定爐小，因而自銳性更好。
3. 磨料顆粒尖角少，圓整度高，單位體積的堆積密度高，同等尺寸的砂輪中參與磨削的磨料多，可提高砂輪的使用時(shí)間。
4. 特殊的制砂工藝，使棕剛玉磨粒中的裂紋數(shù)量控制在一定范圍內(nèi)，經(jīng)過高溫?zé)谱龀缮拜啿灰桩a(chǎn)生啞聲、裂紋等缺陷。
