【摘要】：随着社会经济的高速增长,在城市人口高速增长的同时,中国铝工业正在经历从快速井喷式发展到逐步逐年放缓到新常态阶段,但随着国家积极推动诸如“一带一路”、“绿色经济”、“工业4.0”、“十三五规划”、等等一系列促进国家经济发展的利好政策出台会对未来经济持续快速发展输入更为多样化的新鲜血液,并且提供源源不断的动力。经济的持续发展促进人民的生活质量水平不断提高并追求更为高质量的生活,铝产品作为现代化经济和高新技术发展的支柱性原材料对建筑幕墙、交通运输、电力设备、国防军工、包装、高端装饰等时刻扮演着人们生活的重要角色,同时,国家大力倡导拓展用铝替代钢铁、木、纸、铜、塑料等非环保类的材料促使铝产品不断推出新产品、新工艺、新用途,从而推动整个行业技术进步和行业持续健康发展。放眼世界铝工业在蓬勃发展同时产能过剩问题则表现的越来越突出,产能过剩的主要原因是中国产能的爆炸式增长,早几年前行业内就已经预计了电解铝市场产能过剩,同时国家也在一直出台各种各样的政策淘汰这些落后的产能保证市场的良性发展,但事实是减产量远远落后于产能投放量,过多增加的产能和消费能力不成正比导致近年来铝供应过剩情况矛盾一直没有得到很好的解决,因而转型升级、节能减排就成了化解这一矛盾的突破口。3104系列铝合金材料是人们日常生活中饮用的易拉罐料的原材料,由Al,Mn,Mg,Si,Cu,Fe,Zn及其它少量元素构成,物理特性表现为强度高、密度小、抗腐蚀性好、易成型等,在其生产工艺中宏观力学性能和微观组织性根据元素配比的不同会出现较大的差异,本文研究的课题就是怎么找到这些较大差异以及怎么处理好这些差异从而能够大批量的生产出合格的3104系列铝合金材料。
[Abstract]:With the rapid growth of social economy and the rapid growth of urban population, China's aluminum industry is experiencing a rapid development from a rapid blowout to gradually slow down to the new normal stage year by year. But with the country actively promoting such as "Belt and Road", "Green economy", "Industry 4.0", "Thirteenth Five-Year Plan". And so on a series of good policies to promote the national economic development will bring in more diversified new blood to the future sustained and rapid economic development. The sustainable development of economy promotes the improvement of people's quality of life and the pursuit of higher quality of life. Aluminum products as a pillar of modern economy and high-tech development of raw materials for building curtain walls, transportation, power equipment, national defense industry, packaging, high-end decoration and other times plays an important role in people's lives. At the same time, the country vigorously advocated the expansion of aluminum instead of steel, wood, paper, copper, plastics and other non-environmental protection materials, aluminum products continue to introduce new products, new processes, new applications. In order to promote the technological progress of the whole industry and the sustained and healthy development of the industry, the aluminum industry in the world is booming while the problem of overcapacity is becoming more and more prominent. The main cause of overcapacity is explosive growth in China, where excess capacity in the electrolytic aluminium market was expected years ago. At the same time, the country has been introducing a variety of policies to eliminate these backward capacity to ensure the sound development of the market, but the fact is that the output is far behind the production capacity. Excessive production capacity and consumption capacity is not proportional to the aluminum supply surplus in recent years has not been well resolved, so the transformation and upgrading. Energy saving and emission reduction has become the breakthrough point to resolve this contradiction. The aluminum alloy material of series 3104 is the raw material of the potable can material in people's daily life. The physical properties of Zn and other small amount of elements are high strength, low density, good corrosion resistance, easy forming and so on. In the process of production, there will be great differences in macroscopic mechanical properties and microstructures according to the different proportion of elements. The subject of this paper is how to find these great differences and how to deal with these differences so as to produce qualified 3104 series aluminum alloy materials in large quantities.
