The objective of this collaborative research is a scientific understanding sufficient to enable casting of metallic sheets, ribbon or foil, of commercially acceptable quality, directly from the molten metal state. Experimental testing along side computational and mathematical modeling will be used to achieve the desired understanding. From aluminum foil to airplane wings, most metallic components used today are formed from flat pieces. As in current commercial practice, mechanical rolling and thermal annealing stages have high energy, environmental and capital costs. The goal is to develop processes to solidify raw material directly into final product, without downstream processing steps. This is a vision that goes back to Bessemer (1865) and its realization would revolutionize thin-sheet manufacturing. The casting method forces molten metal into contact with a spinning cold wheel where the metal solidifies and is spun off. Manipulation of the contacting and solidification events is the focus.As compared to current practice, there would be direct energy savings for single-step casting. Indirect benefits include the reduction of greenhouse gases, particularly, carbon dioxide. Capital costs for manufacturing would be reduced and productivity would be increased. Both environment and industry benefit. As China and India industrialize and the demand for flat products grows, these benefits to society will accrue. A further benefit will be through education. Undergraduates and graduates will be involved in this research as a problem-solving team, with educational outreach to local schools.

这项协作研究的目的是一种科学理解，足以使金属金属状态直接从商业上可接受的金属板，缎带或箔铸造。侧面计算和数学建模的实验测试将用于实现所需的理解。 从铝箔到飞机翅膀，当今使用的大多数金属组件都是由平坦的碎片形成的。与当前的商业实践一样，机械滚动和热退火阶段具有高能量，环境和资本成本。目的是开发过程，将原材料直接固定在最终产品中，而无需下游处理步骤。这是一个可以追溯到Bessemer（1865）的愿景，其实现将彻底改变薄页制造。 铸造方法迫使熔融金属与金属固化并旋转的旋转冷轮接触。 操纵接触事件和固化事件是重点。与当前的实践相比，单步铸造将有直接的节能。 间接好处包括减少温室气体，尤其是二氧化碳。制造的资本成本将降低，生产率将提高。环境和行业受益。 随着中国和印度工业化以及对扁平产品的需求的增长，这些对社会的好处将产生。 进一步的好处将是通过教育。本科生和毕业生将作为解决问题的团队参与这项研究，并向当地学校进行教育宣传。
