Abstract
The invention discloses a process for recovering aluminum scraps, which comprises the following steps of: magnetic separation: carrying out magnetic separation on aluminum scraps containing ironcontamination; cake pressing: pressing aluminum scraps subjected to magnetic separation into aluminum blocks; and smelting: smelting the cake-shaped aluminum blocks to be poured into a product. In the invention, by adding the step of magnetic separation before the cake pressing process, the ironcontamination in the aluminum scraps is sucked out by magnetic force of a magnetic separator, so that only aluminum scraps are left in the aluminum scraps containing the ironcontamination. The process has a small amount of investment and high efficiency. With the process, the investment cost can be saved by several hundred thousand yuan relative to the mature complete set technology at home. The oxygenation loss ratio of direct returning smelting after cake pressing is close to the aluminum ingot melting loss ratio and is greatly reduced compared with the oxygenation loss ratio of direct returning smelting of aluminum scraps because the surface area is greatly reduced, the heat transfer speed is high, and the aluminum scraps are easily smelted into aluminum water. By adopting the process flow, the loss ratio of aluminum scraps is controlled to be about 5%, and the iron content of aluminum scraps is controlled below 0.2%.
