项目摘要

We anticipate that the demands for sand, clay, and coal could be diminished by 40-75% when foundries employ a novel ultrasonic-cavitation process to reclaim green sand and bag house dust. At PSU will conduct nano-scale analyses of reclaimed green sand and bag house dust samples that he collected during successful pilot trials of this process at Neenah. The objectives are to: (1) advance the capabilities of this ultrasonic-cavitation process for cleaning and separating the components of waste green sand and waste bag house dust, so that the sand, clay, and coal can be reused in the iron foundry; (2) advance the fundamental understand of this process so that it can be yet further improved. Nanoscale analyses will include electron microscopy, x-ray spectroscopy, pore structure, surface charge, water sorption, and TGA-mass spectroscopy. From these analyses, we will devise yet better modes of ultrasonics-cavitation processing, for use at Neenah Foundry and others. As intellectual merits, our team will develop a fundamental understanding of how the nano-scale characteristics of these materials impact performance-related properties of green sand systems. As broader Impacts, this research will yet further enhance the infrastructure of an eight-year partnership among Penn State, Neenah (and other) foundries, and Furness-Newburge. This ultrasonic-cavitation process could annually save US foundries $0.5-4 billion.

我们预计，当铸造厂采用新颖的超声浪费工艺来收回绿沙和袋装房屋灰尘时，对沙子，粘土和煤的需求可能会减少40-75％。在PSU，将对他在Neenah成功进行试验试验期间收集的回收绿色沙滩和袋装粉尘样品进行纳米级分析。目标是：（1）提高这种超声浪费过程的能力，以清洁和分离废物绿沙和垃圾袋屋的灰尘，以便在铁铸造厂中重复使用沙子，粘土和煤炭；（2）促进对此过程的基本了解，以便可以进一步改进。纳米级分析将包括电子显微镜，X射线光谱，孔结构，表面电荷，吸附和TGA-MASS光谱法。从这些分析中，我们将设计出更好的超声浪费处理方式，以在Neenah Foundry和其他人使用。作为智力优点，我们的团队将对这些材料的纳米级特征如何影响绿沙系统的性能相关特性有基本的了解。随着更广泛的影响，这项研究将进一步增强宾夕法尼亚州立大学，尼纳（Neenah）（和其他）铸造厂和Furness-Newburge之间八年合作伙伴关系的基础设施。这种超声浪费的过程每年可以为我们节省5-4亿美元的铸造厂。
