Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] Such as figure 1 as shown,

[0024] Secondary aluminum production process, the specific process is:

[0025] a. Prefabrication of waste aluminum 1. First, primary classification of waste aluminum is carried out, and graded stacking is carried out. For waste aluminum products, they should be disassembled to remove steel and other non-ferrous metal parts connected with aluminum materials, and then cleaned, crushed and magnetically separated. , drying and other processes to make waste aluminum materials; waste aluminum often contains paint, oil, plastic, rubber and other organic non-metallic impurities, which must be removed before returning to the furnace for smelting.

[0026] b. Ingredients 2, according to the preparation and quality of...

Abstract

The invention relates to a secondary aluminum production process, relating to the waste aluminum smelting process field. The secondary aluminum production process is characterized in that the specific process flows are as follows: prefabricating a waste aluminum material, namely performing primary classification and disassembly on waste aluminum and removing other non-ferrous metal parts; selecting minor ingredients and calculating the dosages of various materials according to demands; smelting, namely sending the prepared waste aluminum material in a smelting furnace to smelt; introducing the smelted aluminum melt in a refining purification furnace to refine; detecting aluminum melt with a spectrograph, analyzing the contents of various chemical elements; using the refined aluminum melt to perform casting moulding; inspecting the finished products to ensure that the chemical element contents of the products all meet the national standard; and bundling up the qualified products, packaging and warehousing. The invention has the following beneficial effects: the secondary aluminum production process has the advantages of low energy consumption, fewer emissions and is resource-saving, and waste aluminum can be used to synthesize aluminum alloy ingots in one step which meet the national standards and are used for pressure casting and casting.

Description

Technical field: [0001] The invention relates to the field of scrap aluminum smelting and processing technology, in particular to a secondary aluminum production technology. Background technique: [0002] Aluminum is currently the most used metal in the world besides steel. Since my country's reform and opening up, the aluminum industry has developed rapidly. [0003] The use of aluminum is very wide, and aluminum and aluminum alloys are almost omnipresent in all walks of life. With the increase of aluminum production and usage, the amount of discarded aluminum products is also increasing, and many aluminum products are disposable, and the time from product use to loss of use value is relatively short. Therefore, these discarded aluminum products and aluminum miscellaneous materials may become a source of pollution. The issue of how to recycle waste aluminum has become very urgent. From ore to metal, and then to finished products, aluminum is costly and energy-intensive....
