| 摘 要： | 将废旧铝合金循环利用制备再生铝对缓解资源压力和节能环保都有重要意义,有力地推动了铝合金制造业的绿色可持续发展。而颗粒增强的铝合金基体中弥散且均匀地分布着大量微米级颗粒(碳化硅、氧化铝等),常规分离手段难以实现其高效富集。超重力分离在金属熔体提纯和非金属夹杂物去除等领域已得到较为广泛的研究,将增强颗粒作为合金中的夹杂物,以碳化硅增强的6061铝合金为实验原料,在G=800、反应温度为750℃条件下,10分钟内实现了增强颗粒与合金基体的高效分离,为其它增强体铝合金的循环再生提供了典型范例。

| Abstract: | The recycling of end-of-live aluminum alloys to produce secondary aluminum is of great significance to alleviating resource pressure, energy conservation and environmental protection, which effectively promotes the green and sustainable development of aluminum alloy manufacturing. However, a large number of micron-sized particles (SiC, Al2O3, etc.) are dispersed and evenly distributed in the particle-reinforced aluminum alloy matrix, and it is difficult to achieve high-efficiency enrichment by conventional separation methods. High-gravity separation has been widely studied in the fields of metal melt purification and non-metallic inclusion removal. Herein, the reinforced particles are used as the inclusions in the alloy, and the 6061 aluminum alloy reinforced with silicon carbide was used as the experimental raw material. When gravity is 800 and the reaction temperature is 750°C, the efficient separation of the reinforcement particles and the alloy matrix is achieved within 10 minutes, which provides a typical example for the recycling of other reinforcement aluminum alloys. |
