Since July 2012, all production facilities at the
foundry have been working with PSI’s production control system. The project has improved the energy balance, boosted productivity and cut lead times. The optimization of raw materials/materials efficiency has also made energy procurement more flexible for maintenance and repair work. FWH is part of the Georgsmarienhütte Group with customers from the conventional power engi- neering sector, mechanical engineering, heavy-duty engines, the minerals and the steelworks industry, as well as wind energy. As a traditional large-scale iron foundry, FWH manufactures products weighing between 8 and 160 tons. PSI Metal’s specialists had already come up with a concept for a manufacturing execution system and shop-floor data collection based on earlier analysis of actual values and implemented it at FWH in 13 months. The Fraunhofer Institute for Factory Operation and Automation IFF, which is based in Magdeburg, offered advice on energy optimi- zation for melting processes. This project represents the first time the energy efficiency factor has been introduced in a manufacturing execution system as a relevant control parameter. Work processes at large metalcasting facilities are
自2012年7月起，FWH的所有铸造生产设备都纳入 了PSI Metal的生产控制系统。该项目在促进能耗结 构平衡、提高生产力和缩短交付周期方面取得了不少 佳绩。此外，随着原材料/材料利用效率的不断优化， 为设备保养和维修所进行的能源采购活动也变得更为 灵活。
FWH为Georgsmarienhütte旗下企业，客户来源 于普通电力工程行业、机械工程行业、重型发动机行 业、矿产及钢铁行业，以及风能行业。FWH作为一家 传统大型铸铁厂，其产品重量在8-160吨之间。基于 对实际值进行的早期分析，PSI Metal提出了制造执 行系统和车间数据控制这一概念，并在FWH推行了13 个月。位于马格德堡的弗朗霍夫工厂运作与自动化研 究所，为熔化程序提出了能源优化的建议。通过该项 目，能耗因素作为相关控制参数，首次被引入到制造 执行系统中。
过去，大型铸铁工厂的工作流程很少会被组织起 来集中运作。相反，它们历来被认为是相互独立的步
