技术领域technical field
本发明属于合金制备技术领域，具体是涉及一种变形铝合金的废铝再生方法。The invention belongs to the technical field of alloy preparation, and in particular relates to a waste aluminum recycling method for deformed aluminum alloys.
背景技术Background technique
变形铝合金通常是指塑性较高，适于挤压、轧制、锻造、冲压、弯曲等压力加工的铝合金。变形铝合金是目前应用最广泛的一类有色金属结构材料，大量用于建筑、电子电器、电线电缆、汽车、船舶、机械装备、航空航天、武器装备等领域。随着我国经济社会的飞速发展，对变形铝合金的需求日益增多。Deformed aluminum alloys usually refer to aluminum alloys with high plasticity and suitable for extrusion, rolling, forging, stamping, bending and other pressure processing. Wrought aluminum alloy is currently the most widely used non-ferrous metal structural material, and is widely used in construction, electronic appliances, wires and cables, automobiles, ships, mechanical equipment, aerospace, weaponry and other fields. With the rapid development of my country's economy and society, the demand for deformed aluminum alloys is increasing.
对文献资料检索发现，现有技术主要以原生铝为原材料，在熔炼铸造过程中加入铜、镁、硅、锰、锌等合金元素来制备变形铝合金。众所周知，原生铝是由氧化铝电解得到，而氧化铝的电解属于高能耗行业，再加上铝矿资源的开采和氧化铝生产，导致原生铝的生产需要消耗大量的能源，同时还会排放大量的二氧化碳、粉尘和固体废弃物，造成严重的环境污染，最终导致变形铝合金的生产成本较高。A literature search found that the existing technology mainly uses primary aluminum as a raw material, and alloy elements such as copper, magnesium, silicon, manganese, and zinc are added in the melting and casting process to prepare deformed aluminum alloys. As we all know, primary aluminum is obtained by the electrolysis of alumina, and the electrolysis of alumina is a high-energy-consuming industry. Coupled with the mining of aluminum ore resources and the production of alumina, the production of primary aluminum requires a large amount of energy consumption and a large amount of emissions. carbon dioxide, dust and solid waste, causing serious environmental pollution, and ultimately leading to higher production costs of deformed aluminum alloys.
我国是铝及铝合金的生产和消费大国，每年会源源不断的产生大量的废铝。利用废铝来再生铝合金，可以显著降低铝合金的生产成本，并减少能源的消耗以及二氧化碳、粉尘和固体废弃物的排放。但目前我国大部分的废铝主要用于再生低附加值的铸造铝合金，废铝中含有的铜、镁、硅、锰、锌等合金元素并没有得到有效利用，造成资源的巨大浪费。因此，利用废铝直接再生高附加值的变形铝合金，对于提高废铝的使用价值、降低变形铝合金的生产成本都具有十分重要的意义。my country is a big country in the production and consumption of aluminum and aluminum alloys, and a large amount of scrap aluminum is continuously produced every year. Using waste aluminum to regenerate aluminum alloy can significantly reduce the production cost of aluminum alloy, and reduce energy consumption and emissions of carbon dioxide, dust and solid waste. However, at present, most of the waste aluminum in my country is mainly used to regenerate low value-added cast aluminum alloys, and the alloying elements such as copper, magnesium, silicon, manganese, and zinc contained in waste aluminum have not been effectively utilized, resulting in a huge waste of resources. Therefore, using scrap aluminum to directly regenerate high value-added wrought aluminum alloys is of great significance for increasing the use value of scrap aluminum and reducing the production cost of wrought aluminum alloys.
