Abstract
Press hardening is an established process for producing high-strength, lightweight structural automotive parts, utilising roller hearth furnaces to heat metal sheets. It presents a non-negligible source of greenhouse gas emissions in part production processes. This paper investigates the ecological and economic advantages of induction as an alternative heating method and identifies break-even scenarios. Therefore, specific energy demands for various furnace and induction heating operating states are determined and applied to different energy system transition scenarios. It can be shown that while induction heating can be more energy efficient than furnace heating, its ecological and economic advantages are highly dependent on regional electricity-to-gas price ratios and electric energy emission factors. For high good-mass flows (0.5 kg/s) and 80% production capacity utilisation, an electricity-to-gas price ratio lower than 1.24 and an emission factor lower than 250 g CO2 /kWh are required.
冲压硬化是一种成熟的工艺，用于生产高强度，轻质结构汽车零件，利用辊底炉加热金属板。它是部分生产过程中不可忽视的温室气体排放源。本文研究了感应加热作为一种替代加热方法的生态和经济优势，并确定了收支平衡的情况。因此，确定了各种炉膛和感应加热运行状态下的具体能量需求，并将其应用于不同的能源系统转换场景。可以看出，虽然感应加热可以比炉加热更节能，但其生态和经济优势高度依赖于区域电气价格比和电能排放因子。对于高质量流量(0.5 kg/s)和80%的产能利用率，需要低于1.24的电气价格比和低于250 g CO2 /kWh的排放系数。
期刊介绍：
The Journal of Sustainable Development of Energy, Water and Environment Systems – JSDEWES is an international journal dedicated to the improvement and dissemination of knowledge on methods, policies and technologies for increasing the sustainability of development by de-coupling growth from natural resources and replacing them with knowledge based economy, taking into account its economic, environmental and social pillars, as well as methods for assessing and measuring sustainability of development, regarding energy, transport, water, environment and food production systems and their many combinations.
