Description
技术领域
本发明属于铝加工行业汽车板加工领域,具体地说是一种回收罐盖料用于汽车板的生产方法。
背景技术
回收的罐盖主要合金是5182、5052和5042,这三个合金牌号中各元素各有侧重,需要分类回收和存放,主要是为了让废料的使用最大化,将回收后的废罐盖料使用到汽车板中,此种生产工艺在国内还没有先例,因为在国内同时具备生产罐盖料和汽车板的铝加工厂并不多,而此工艺有效的应用,在国内还处于空白。
使用回收后的废料是来至不同的铝材加工厂,材料的化学成分差异较大,但这些合金中有一个共同的特点是含Mg元素较高,其它杂质元素含量不一样,这对熔体质量的洁净度要求很高,控制难度也较大,为了保证汽车板的产品质量,特研发了本生产工艺,使材料的性能、成型性等各项技术指标满足下游产品的使用要求。
发明内容

步骤二:根据检测的化学成分结果,使用元素去除剂,将合金中含量高的元素降低至工艺要求上限;
步骤三:将废料处理系统熔化后的铝液按40~80%的装炉比例转入到熔炼炉;
步骤四:熔炼炉按Al-Mg系铝合金汽车板化学成分配比,熔炼温度在690~765℃;
步骤五:将合格的铝液转到保温炉内精炼,精炼温度700~760℃,精炼时间20~90分钟;
步骤六:在线除渣、除气、过滤处理,铸造大扁锭,铸造温度660~720℃,铸造速度50~60mm/min;
步骤七:大扁锭铣面,大面铣面量10~25mm,小面铣面量3~15mm;
步骤八:大扁锭均匀化,均匀化温度520~600℃,保温时间3~20小时;
步骤九:热轧终轧温度300~380℃,厚度3~10mm;
步骤十:冷轧成品热处理温度450~580℃;
步骤十一:精整切边成品包装入库。
