Embodiment Construction

[0028] Below in conjunction with the examples, the present invention is further described, the following examples are illustrative, not limiting, and the protection scope of the present invention cannot be limited by the following examples.

[0029] A method for regenerating high-end engine block materials with high-quality aluminum shavings, the specific steps are as follows:

[0030] (1) Put 4t of pure aluminum ingots into a 30t melting furnace and melt to 680-700°C;

[0031] ⑵Start the aluminum chip feeding device, the aluminum chips go through the hopper into the crusher, through the drying machine, magnetic separation equipment, drying kiln, and into the melting furnace. Under the agitation of the mechanical circulation pump, the aluminum chips enter the molten aluminum and melt until 24t of aluminum chips are added. The temperature in the drying kiln is controlled at 200-400°C;

[0032] (3) After adding the aluminum chips, adjust the temperature of the molten aluminum ...

Abstract

The invention relates to a method for reproducing a high-end engine cylinder material with high quality by utilizing aluminium skimmings, comprising the following steps: carrying out pretreatments including crushing, spin-drying, magnetic separation, drying and the like on the aluminium skimmings, and enabling the aluminium skimmings to enter molten aluminum via a mechanical circulating pump. The aluminium skimmings are refined for deslagging in a melting furnace after being totally added, are subjected to refining again for deslagging after being transferring into an alloy furnace, and are finally subjected to online degassing casting under the protection of inert gas. Therefore, primary utilization of the aluminium skimmings can be achieved, and the aluminium skimmings can replace pure aluminium products, thus lowering production cost.

Description

technical field [0001] The invention belongs to the field of recycling aluminum scraps, relates to high-end engine materials, in particular to a method for regenerating high-end engine cylinder materials with high quality aluminum scraps. technical background [0002] The traditional process of recycling aluminum chips is as follows: In some small and medium-sized aluminum scrap recycling enterprises, aluminum chips directly enter the melting furnace without any treatment. During the smelting process, a slag removal process is performed, followed by degassing in the furnace or on-line degassing in the launder behind the furnace, and finally casting into ingots (both the degassing process and the casting process are carried out in a natural state). Because aluminum chips contain a large amount of cutting fluid and Fe impurities, the regeneration process causes great environmental pollution, frequent composition adjustments, and high gas and impurity content in the product.
