Article- 质量问题
华晨宝马已经在中国东北沈阳建立了强大的制造基地 Nick Nolt会面宝马技术与制造高级副总裁Anton Heiss，一探宝马在中国取得成功的秘诀 AMS：有人说铁西工厂是中国可持续性做得最好的汽车制造厂。这个工厂是不是成为整个地区的制造标尺了呢？ Anton Heiss(AH)：你们可以把宝马铁西放到全球网络中比较，这是最新的工厂，我们把宝马许多发展优势拿过来。这个地区夏天非常炎热，而冬天非常寒冷，因此这里的建筑物设计需要高效的冷热系统，才能节省能源。 而且从生产设备上可能，我们拥有两条高速伺服冲压线，上面还有能源恢复系统，要比液压式高效。使用这种技术之后，我们可以在每压节省大约60%的能源。在汽车车体修理厂里，我们回收冷却焊接机器人散发的热能，为工厂提供热能。我们的喷漆厂使用旋转浸渍工艺，通过预处理浸泡旋转车身，既节省了了能源，又节省了空间。 Dr. Anton Heiss senior vice president Technology and Manufacturing, BMW Brilliance Automotive 在为汽车车体喷漆方面，我们使用IPP系统，可以减少一个喷漆步骤。搞系统综合了第一层和第二层漆，中间不需要加热车身；这样就节约了能源和材料，降低了循环时间，提高了产量。我们还在循环过剩清洁涂层方面使用了最新技术。 在装配区域，我们也能循环来自测试和冷却操作中90%的废水。我们还在主要办公大楼节省了大量的水。我们在宝马工厂里采用一切可以可持续性生产的方法，使铁西成为一个标志性工厂。 AMS：你们目前在沈阳生产3系列、5系列和X1车型。你们不久之后会不会增加新的车型或平台呢？ AH：我们计划在未来两年内引进3种车型。一个是初级汽车，入3系列内，这是特别为中国市场设计的。另一款是高端功能汽车，结合了使用性与宝马典型动力系统，面向家庭用汽车市场。然后我们还要制造X3变体系列。 AMS: 目前在中国生产遇到过什么挑战吗？ AH: 主要挑战来自中国的发展速度。如果你对比一下2009年和去年的数据，生产增长了6倍，在5年的时间里，这算是飞速发展了。仅仅对比2013年和2014年，产量就增长了30%。这种增长即便建立高产量工厂，也是一种挑战，但也是容易解决的问题。除了设备和人员培训之外，这算是最大的挑战了。 BMW works closely with suppliers to ensure sequenced parts delivery 我们的当务之急就是质量，这不仅是机器问题，还是人的问题。因此，我们在员工培训上投入很多；工作之外，我们还安排了6周的培训，然后在继续操作。 ...

Article钢材方案
钢材制造商们正在研发更轻、更强的材料，迎接轻质汽车的挑战原始设备制造商在为汽车选择恰当的钢材时一定要有所权衡。钢材需要非常强硬，才能在撞车事故中保护乘客，同时还要很轻，才能减少二氧化碳排放并提高能源效率。为了满足这些需求，汽车制造商正在评估钢材轻质方案，提高应用范围。2014年，Ford开始生产市场为导向的F-150全铝车身，从而登上新闻头条。2015年4月，BMW宣布，2016 7-系列底盘将广泛采用碳纤维复合材料（CFRP），加强主要零部件的结构，包括B-柱和C-柱，以及顶板梁。尽管这些材料的使用成本要比钢高得多，但是这些技术有望在将来10年内发生长足发展。钢材面临的挑战钢材业面对这些挑战并没有坐视不理，而是进行大量投资，研发更加先进的超高强钢（AHSS和UHSS），可以让汽车制造商用更少的材料，制造更多的东西。ArcelorMittal公司欧洲汽车部首席市场营销官Philippe Aubron说，“六七年前，我们将产品中的AHSS含量大概提高了10%，现在达到大约25-30%，而且这个比率将来还会提高。”AHSS是一种极限抗拉强度（UTS）超过500MPa的钢，而UHSS是一种极限抗拉强度超过980MPa的钢。这些材料主要用于白车身（BIW），生产的组件能够在撞车事故中吸收大量能量，比如车辆前段，旁边以及后侧组件。据Tata Steel公司产品市场经理Chris Woofindin说，“UHSS的轻质潜力主要依赖组件的应用和UHSS种类的强度。加入能代替传统的微合金高强度钢（340MPa）— 用于生产需要弯曲强度的组件 — UHSS钢种可以通过降低组件的尺寸，从而降低30-50%的重量。“使用钢材是减少汽车重量最廉价的方法。如果使用铝或CFRP，成本将会高得多” – Philippe Aubron, ArcelorMittal除此以外，使用高成本UHSS，将产生较少的材料补偿；一个轻质UHSS组件的成本很高。Aubron继续说，“使用钢材时减少汽车重量最廉价的方法。如果使用铝或CFRP，成本会很高。铝的成本会高出3-4倍，而CFRP则会更高。原始设备制造商和供应商们已经有冲压机床和焊接机床；万事俱备，因此他们不需要对UHSS进行额外投资。”成型与功能当然，能用铝和CFRP制造的组件也可以使用UHSS制造。尽管UHSS与传统钢材很相似，但是使用起来仍然有很多困难。 Extensive use of advanced steel grades in a typical C-segment vehicle在所有困难中，排在第一位的是成型。比如，马氏体钢种 — 正如其名 — 主要成分是马氏体加上少量铁酸盐和贝氏体。SSAB公司于2014年引进Docol 1700M马氏体钢（抗拉强度达到1,700MPa），能量吸收力极强。这种材料特别适合生产轻质钢材保险杠。然而，这种钢极难成型，只能用滚轧成型。Woofindin说，“使用具有高强度材料的困难在于，最终成型不能出现任何材料断裂或回弹造成的高程度变形。”在对平板材料完成冷处理时，会释放成型力，材料会因为弹性特性而恢复成原来的形状。这种回弹受到很多因素的影响，比如抗拉强度和抗屈强度。热冲压生产较复杂集合结构的组件、又可以限制回弹问题的一个方法就是热冲压技术。该技术是由SAAB公司于1984年首次应用于汽车制造业 — 就是将一个板材放到熔炉里加热至900°C，形成一个内部冷却的冲压模座，然后在每秒冷却速度在27°C的压力下淬火。这种最低冷却率保证了马氏体钢微观结构的成型，并保持高强度。“使用具有高强度材料的困难在于，最终成型不能出现任何材料断裂或回弹造成的高程度变形” – Chris Wooffindin, Tata Steel为了实现这种工艺，开发了硼钢，比如ArcelorMittal公司开发的Usibor 1500和Tata公司的HQ1500，这两种材料的抗拉强度在也冲压之后都达到1,500 MPa。制造的组件在最后成型之后都具有高准确性。从加热板材到冲压的整个过程，只需要5至10分钟，熔炉技术改进之后，每个零部件的生产过程需要20秒钟左右。热冲压技术在汽车制造业的应用越来越普遍；Volvo XC90的白车身的40%都是用这种工艺。然而，热成型所需能源，使得该技术的成本要比冷成型高得多。回弹模拟制钢业已经开发了电脑模拟程序，能让客户预测到组件的回弹过程，让他们修改冷成型技术，限制回弹。此外，许多第三代AHSS和UHSS钢种都接近商品化阶段，将来更容易以室温进行成型。2014年，ArcelorMitaal宣布开发成功冷冲压可塑性AHSS，这可以使用双期钢，将组件的重量降低20%。为了替代DP钢种，ArcelorMittal在法国和美国研发了Fortiform钢种。Fortiform钢种目前包括3个钢种。Fortiform 1050是第一个出现在市场上的钢种。由于具有高抗拉强度，Fortiform1050钢种特备适合生产需要吸收能力强的零部件。这种钢在轴向挤压试验中表现突出，使用了欧米茄结构，拥有56 km.h–1冲击速度点焊封板。第一批使用这种材料的车辆，将于2017年面世。其他两个钢种是Fortiform980和Fortiform1180，将于2017年完成。制造商已经得到样品，在2014年就进行测试，工业产品从2015年就投入市场。其他产品也将陆续出现。公司称，原始设备制造商不需要对生产线进行大量改动，就能使用新的钢种。只需要在点焊参数上进行稍微改动 — 由于碳的增加，就需要增加电极压力，调节焊接周期 — 但是，由于制造某个零部件的所需钢材要比DP钢种少，因此在生产线上使用这种钢种不会产生任何附加成本。 Vehicles components must adsorb large amounts ...
