在从液态金属生产铝的各个步骤中，由于加工操作产生了大量的废料。因此，铝废料的回收利用是一个有趣的主题，因为这种金属的广泛应用和用于回收金属废料的低效率的过程。介绍了一种低能耗、低成本的废铝直接回收新技术。测量的性能包括生坯密度、抗压强度和硬度。实验结果表明，直接法再生铝生产效率高，（烧结前）绿密度达80%左右。此外，与传统方法相比，新技术具有极低的空气污染排放和高的金属节约。(C) 2003 Elsevier Science B.V.版权所有
During the various steps of aluminium production from liquid metal, a lot of scrap is generated due to machining operations. Therefore, recycling of aluminium scrap is an interesting subject because of the broad applications of this metal and low efficiency of processes used to recycle metal scrap.This paper introduces a new direct technique for recycling aluminium scrap with low energy consumption and cost without intervening metallurgical processes. Measured properties include green density, compressive strength, and hardness. Experimental results obtained show that the direct technique for recycled aluminium provides high productivity and about 80% green density (before sintering). In addition, the new technique provides very low air pollution emission and high metal saving as compared with conventional methods. (C) 2003 Elsevier Science B.V. All rights reserved.
