AP&T's life cycle analyses map the climate impact of press hardening AP&T 生命周期分析可绘制热成形产线对气候的影响

How big an impact on the climate does a press-hardening line have during its lifetime? And how does the use of press-hardened parts affect the climate performance of vehicles? This is information that many vehicle manufacturers are requesting and that AP&T can now provide. 

热成形产线在整个生命周期内对气候的影响有多大？使用热成形零件的车辆如何影响气候？这是许多汽车生产商需要了解的信息，现在AP&T可以提供。

In collaboration with RISE, AP&T has comprehensively analyzed the life cycle of a typical press-hardening line. The analysis covers the climate impact at all stages of a line that is assumed to be in use for 20 years, from the extraction of iron ore to the recycling of the machine at its end-of-life. Continuous maintenance and a reconstruction of the line are also included in the calculations.

AP&T与瑞典RISE公司合作，对一条典型的热成形产线在整个生命周期的表现进行了全面地分析：假定使用期限20年，从铁矿石开采到设备报废时回收，其中设备的持续维护和改造升级均包含在内，所有阶段对气候的影响。

In addition, they have analyzed how the total climate emissions from the end product – a passenger car – are affected by the components used in its structure. 

此外，他们还分析了使用了热成形零件的最终产品：乘用车，如何影响总的碳排放量。

“The data that life cycle analyses provide primarily give us a stable basis for our own continued climate work and help us more easily prioritize which measures we should focus on. In addition, we can offer our customers a third-party audited, factual basis that helps them calculate and report the total climate impact of their products and make the right decisions for the future,” says Christer Bäckdahl, CTO at AP&T.

AP&T首席技术官Christer Bäckdahl表示：“生命周期分析提供的数据不仅为可持续发展工作提供稳定的基础，还让我们更容易地考量应优先采取的措施。此外，我们可以为客户提供经第三方审计的事实数据，帮助计算和报告其产品对气候的总体影响，以便客户为未来做出正确的决定。”

Many factors affect the outcome

影响结果的多个因素

There are many parameters that affect the scope of the climate impact a press-hardening line has during its life cycle, and these vary from case to case. In general, AP&T's analyses show that the absolute majority of climate emissions are related to energy consumption during the operational phase. But the extent is determined to a great degree by the energy mix – i.e., the energy sources used to produce the electricity needed to run the line. Hydro and wind power have very little climate impact, while emissions from fossil energy sources such as coal, oil and fossil gas are significant.

有许多参数会影响热成形产线在其生命周期内对气候的影响范围，而且这些参数因情况而异。总的来说，AP&T  分析表明，绝大多数碳排放量与设备运转阶段的能源消耗有关。但在很大程度上取决于用于设备运转所需电力的能源组合：水力和风能对气候的影响很小，而煤炭、石油和化石气等化石能源产生的碳排放量很大。

“Energy consumption during the operational phase is decisive for the scope of a press-hardening line's total climate impact during its life cycle. Choosing energy-efficient machinery, such as AP&T's servohydraulic press, can reduce the climate footprint and energy costs significantly,” says Christer Bäckdahl, CTO at AP&T.

AP&T首席技术官Christer Bäckdahl表示：设备运转阶段的能源消耗对热成形产线在整个生命周期内对气候的影响具有决定性作用。选择节能设备，如AP&T  伺服液压机，可以显著减少气候影响和能源成本

“This entails different outcomes depending on where generation takes place. Sweden's energy mix, for example, has only one-fifth the climate impact of Britain’s. But regardless of where production is located, it is always important to optimize energy use and choose energy-efficient alternatives. Take, for example, our servohydraulic press, which is up to 70 percent more energy efficient than our conventional hydraulic presses.”

“由于使用地点的不同，也会带来不同的结果。例如，瑞典的能源组合对气候的影响只有英国的五分之一。但无论使用地在哪里，优化能源使用和选择节能替代品是很重要的。以AP&T  伺服液压机为例，它的能源效率比传统液压机高出70%。”

An interesting question is how a finished car performs climate-wise during its life cycle in relation to the materials used to manufacture its structural parts. If you factor in the steel-making process and parts manufacturing, which is better: press-hardened steel or cold-formed high-strength steel?

一个有趣的问题是，如果将生产汽车所用的材料作为因素，其在生命周期内对气候的影响如何。炼钢工艺和零件制造，哪种更好：热成形零件还是冷冲压高强度钢零件？

“Thanks to the fact that press hardening strengthens the steel, less material is required for each part. This gives a lower weight, making the car lighter than when using cold-formed steel. This has a positive effect on the car's energy consumption and climate impact, which compensates, by a good margin, for the emissions arising from material production and component manufacturing,” says Bäckdahl.

Bäckdahl 阐述到：“由于热成形技术可以提升钢材的强度，因此每个零件所需的材料更少。这会降低汽车的重量，使汽车比使用冷冲压钢时更轻。这对汽车的能源消耗和气候影响有正面影响，很大程度上补偿了材料生产和零部件制造所产生的碳排放。”

Considering that many car manufacturers are asking for the type of information a life cycle analysis can provide, AP&T is expecting to do more analyses of specific lines and products in the future.

目前许多汽车生产商都在咨询生命周期分析可以提供的信息类型，AP&T未来会针对特定的生产线和产品进行更多的分析，以满足客户需求。

“We will be developing this offer because we know many customers will benefit from it,” says Bäckdahl.

Bäckdahl表示：“生命周期分析将使许多客户从中受益，我们将推出此项服务方案。”

Also in collaboration with RISE, AP&T has recently carried out a corresponding life cycle analysis of a production line for hot forming of high-strength aluminum.

此外，AP&T最近还与RISE合作，对高强度铝热成形生产线进行了相应的生命周期分析。
