Today, specifically developed casting additives ensure the quality of ever-larger cast parts. Te optimization of control systems for sand mixing equipment also plays an important role in the production process. Te adaptation of Torgelow’s furan resin system and the dosing of the mixer had to be oriented to the dimensions of large-scale cast parts. Te objective was to quickly mix the sand for the 80-ton cast parts, while working effectively in the process. Tis required that the furan resin system be equipped with specifically optimized components and that the correct mixing ratios be applied. Promptness, economic viability and precision were indispensable requirements. Te requirements were solved within the framework of the strategic partnership consisting of ASK Chemicals specialists, mechanical engineering man- ufacturers and in-house specialists. Today, the iron casting facility operates with sand mixing systems with extremely accurate dosing precisely optimized to large-scale casting. For the selection of suppliers, Torgelow considers not only
price, but other important assets as well. Greater importance is placed on deliverability, so the production sequence is not jeapordized—a possible risk that is often overlooked in times of economic pressure. A particular strength of ASK Chemicals in this part- nership is its single-source structure. Torgelow obtains everything it needs with respect to foundry chemicals from Hilden. In the meantime, ASK Chemicals is also responsible for warehousing and logistics. Te iron foundry currently operates at a standard capac-
ity of 70 tons of sand mixture in a ratio of 1:6 per hour. In the casting process itself, 80% of the sand is subject to high temperatures. In the opinion of technical experts in Torgelow, this process is still polluted with too much carbon and sulfur. As the foundry team sees it, the regeneration of the sand must be optimized from a chemical, wet-chemical or physical standpoint such that annealing loss is reduced. For the research team at ASK Chemicals, it was a challenge to develop its binder system to meet the requirements. Weilguni has been impressed with the collaboration with ASK Chemicals. For him, adherence to agreements and a
铸造厂提供生产这些铸件的核心质量控制。 ASK化学品公司的贡献主要是硫边界层和特殊树 脂的适用性，该树脂表现出很高的光滑性或表面光洁 度，这样就能够承受很高的热冲击载荷。 铸件的均匀化硬化是一个特殊的挑战。今天，专 门开发的铸造添加剂保证生产更大铸件的质量。混 砂设备控制系统的优化也在生产过程中扮演了重要角 色。Torgelow公司的呋喃树脂系统和混砂机加料系 统不得不面向大型铸件的生产。目标是快速混砂用于 生产单重80吨的铸件，还要高效率。这需要呋喃树脂 系统要装备专门进行优化过的零部件和采用正确的混 砂比例。推动力、经济有效性和精度是不可或缺的要 求。这些要求要在战略伙伴ASK化学品公司、机械工 程制造者和车间内专家框架内进行消化解决。今天， 铸铁厂采用的混砂设备具有专门为生产大型铸件而优 化的极其精确的加料系统。 对于选择供应商，Torgelow公司不仅将价格作为一 个决策因素，还将重要资产作为重要因素。我们还更 加重视供应商的供货能力，这是为了不致于使生产流 程受到破坏，而这是在经济困难时经常被忽略的可能 的冒险。在合作伙伴方面，ASK化学品公司的特殊优 势是其单资源结构。Torgelow公司能够从Hilden市的 ASK公司获得所有有关铸造的化学品。同时，ASK化 学品公司也负责仓储和物流。
该铸铁厂现在的标准混砂能力为70吨，每小时比例 为1:6。在铸造过程中，80%的砂子受制于高温问题。 从Torgelow公司的技术专家来看，该过程还被太多 的碳和硫所污染。铸造团队认为砂子的再生必须从化 学、湿化学的或物理的角度进行优化，可以减少回火 损失。ASK化学品研究团队认为开发满足这些需求的
