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 of all, follow the aluminum water obtained in the first to fifth steps, and after the sixth step is qualified, add 6.5% silicon, 4% magnesium, 2.4% molybdenum, 4% strontium, and add enough Aluminum water refining agent for refining.

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

[0033] Again, within 40 minutes, the recycled aluminum water and the new aluminum water are casted according to the ratio of 1:5 to obtain a smooth surface of the cast aluminum piece without silver streaks, cracks, etc., and after the use of magnetic particle testing or ultrasonic testing , In order to find defects such as bubbles and blisters inside the casting.

[0034] The aluminum scrap recycling method of the present invention adopts simple equipment to complete the recycling of waste aluminum scraps, saves aluminum recycling costs and ma...

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 aluminum scrap. Background technique [0002] For workshops where aluminum parts are widely and frequently used, especially workshops where aluminum castings are used more often, after the aluminum parts are cast, precision machining is required, and the precision machining process often produces a lot of aluminum chips. Generally, it can only be discarded, which is wasteful. Therefore, if you want to use aluminum scrap waste, if you want to process the aluminum scraps to the shape of a large aluminum piece for reuse, the cost is higher and the process is more complicated. [0003] For this reason, this application provides a method for recycling aluminum scraps, thereby increasing the utilization rate of aluminum. Summary of the invention [0004] In order to overcome the above shortcomings of the prior art, the p...
