- 铸造学习者
对铸造技术的学术研究正在帮助OEM制造商和供应商获得相关知识在过去,几乎汽车制造中使用的每一片金属都要经过铸造加工过程 — 不管是塑型称砂模铸造还是简单的气缸体,都要经过挤压这样的工序。所有的金属都要这样,比如所有的钢铁、铝合金、铜和镁。此外,所有的金属的下游性能条件都要由铸造工序决定,比如强度、表面质量。在任何制造类型中唯一例外的可能就是使用特殊材料,比如通过粉末冶金形式加工的钨。伦敦布鲁内尔大学先进凝固技术布鲁内尔中心(BCAST)副主任Dr Ian Stone简单总结了主要技术在金属制造工序的重要性。BCAST在金属加工技术方面已经有15年的历史的,该中心刚刚宣布了毅力写新规划,主要是为了推动铸造技术的发展,适应21世纪制造业的需求,尤其是汽车业。其中最为突出的就是先进金属铸造中心(AMCC),企业市值达1,700万英镑(约合2,500万美元),得到很多汽车制造商的支持,比如JLR公司,以及铝供应商Consetellium公司的还吃。Dr Stone解释说,尽管铸造技术对汽车业的发展避无可避,但是在很多方面都不利于汽车制造商和材料供应商的研究活动。汽车制造商通常“不具有”铸造厂。与此同时,拥有技术的材料供应商通常不愿意破坏日复一日的大规模制造工艺,而去生产相对数量较少的试验材料。填补空白相反,学术研究机构能够有效填补技术空白。Dr Stone称,机构能够生产适当批量的材料,用于研究,模拟行业条件下的真实使用过程。他说,“我们能铸造200公斤的材料,但不是行业价格”。她继续说,因此AMCC的经营模式非常特别。他说,“我们不能说这是全球唯一,但是这确实在欧洲与众不同。” Aluminium supplier Constellium is partnering JLR and Brunel University to form the Advanced Metal Casting Centre ventureAMCC的工作重点是铝和镁。这里的许多设备都是为了在真是工业环境下进行复制用的。其中包括: 一个1,600吨闭合压力的铸模盒,用于铝镁合金铸造 一个240公吨闭合力的低压铸模盒 一个1,600万吨的顺挤压力,带有锥形二次加热 一个试点规模热顶直接冷却铸工,适用于2米长的钢坯和204厘米直径的钢坯 一个双滚筒铸件,融合了布鲁奈尔自己的熔接条件技术 高分辨率实时X光检测技术重要的是,前三个被称为具有“商业”规模。尽管如此,Dr Stone称,有些设备经过改造具备了很高的灵活度,满足研究相关的要求。高压铸模盒能够在工作中与铝镁合金迅速换换 — 这在专门长期生产环境中并不要求如此。开发潜力或许与传统生产技术最大的不同就是AMCC的双滚筒熔接条件铸件。正如Dr Stone所说,这个技术在行业中使用,但只是用于“有限的低强度合金”。相反,布鲁内尔正在开发其潜力,想要用于制造薄的镁合金产品。他认为,这个材料很难滚动。布鲁内尔开发的另一个技术是Castparicular,这是铝材料“高剪切融化调节技术”。Dr Stone称,这来源于对大多数护腰零部件的铸造工艺处于“颗粒成核形成早期”的认识。他解释说,通过控制成核技术,就能控制“凝固期间的颗粒大小”以及“合金元素的散步”。重要的是,它能够生产薄壁铸件,并且极大降低了瑕疵比率。Dr Stone称,尽管行业已经试验了这种技术,但是在实际生产中并没有采用。但是,这个技术,正如Dr Stone所解释的那样,潜力远超出目前还非常超群的工艺。比如能够将铝合金碎片用于制造零部件的初期材料,满足汽车业的标准。就目前而言,“这还不可能”。这样的碎片的使用目前还是“不受青睐”,也就是说,循环使用的呼声并不高。但这很可能成为低生产使用材料 — 比如在钢铁制造业中的脱氧剂,以低廉的价格出口到不发达的经济体中,甚至直接送到垃圾场。不管是什么情况,最终的结果就是有可能失去利用这些金属进行再利用,创造高价值制造材料的机会。正如Dr Stone所说的:“如果我们能够合理再利用,这能成为价值来源。” The Constellium University Technology Centre supports the work of engineers, ...
