Problems solved by technology

Generally, it can only be discarded, which is wasteful
Therefore, if you want to use the aluminum scrap waste, if you want to process the aluminum scrap into the shape of a large aluminum piece and reuse it, the cost is high and the process is relatively complicated.

Embodiment

[0031] First, the aluminum water obtained according to the first step to the fifth step above, and after passing the test according to the sixth step, add 6.5% silicon, 4% magnesium, 2.4% molybdenum, 4% strontium, and add enough Aluminum refining agent for refining.

[0032] Secondly, the aluminum water obtained after refining is subjected to slagging treatment to obtain recycled aluminum water, and its temperature is kept between 690-720°C for use.

[0033] Again, within 40 minutes to recover aluminum water and new aluminum water, casting aluminum parts according to the ratio of 1:5, the surface of the cast aluminum parts is smooth, free of silver streaks, cracks, etc., and after magnetic particle testing or ultrasonic testing , In order to find defects such as air bubbles and sand holes inside the casting.

[0034] The method for recycling aluminum chips of the present invention can complete the recycling of waste aluminum chips by using simple equipment, saves aluminum rec...

Abstract

The invention discloses a method for casting an aluminum part from recovered scrap aluminum cuttings, which adopts simple apparatuses, such as magnets, common spectrometers for enterprises and other apparatuses, to monitor various stages in the recovery process in real time, thereby ensuring the aluminum quality. The manufacturing technique is simple, has high recovery rate and can utilize 100% of the scrap aluminum cuttings, and the recovered liquid aluminum is directly used for casting the aluminum part, thereby leaving out many processing links and saving the recovery cost and aluminum material cost.

Description

technical field [0001] The invention relates to the technical field of waste aluminum recycling, in particular to a method for casting aluminum parts by using recycled waste aluminum shavings. Background technique [0002] For the workshops where aluminum parts are widely and frequently used, especially the workshops where more aluminum castings are used, after the aluminum parts are cast, precision machining is required, and a large amount of aluminum chips will be generated during the precision machining process. Generally, it can only be discarded and processed, which is wasteful. Therefore, if you want to use the aluminum scrap waste, if you want to process the aluminum scrap into the shape of a large aluminum piece and reuse it, the cost is higher and the process is more complicated. [0003] For this reason, the present application provides a method for recycling aluminum shavings, thereby improving the utilization rate of aluminum. Contents of the invention [000...
