This Small Business Innovation Research (SBIR) Phase I project will determine the feasibility of developing a highly innovative, low-cost, high-speed opto-electronic sensor capable of continuously monitoring molten metal alloy compositions during casting and melting operations. Development of this sensor is among the highest priority technology needs identified by both the metal casting industry and the aluminum industry in their industry roadmaps of the future. In order to effectively compete, U.S. metal industries must increase their use of low cost scrap and must also find ways to increase production efficiency. The proposed sensor will acquire critical compositional data thousands of times faster than current commercial methods and will operate on a real time basis without the need to place the sensor in contact with the molten metal. At these speeds, a melt shop could produce one extra metal production batch (i.e. heat) per day, amounting to a 15% increase in productivity.The $30 Billion aluminum smelting industry translates to a potential $4.5 Billion increase in production output for little or no additional capital investment other than the sensor system itself. Improved product quality, reduced emissions, energy savings, and increased product yield will result from the shorter melting times. Similar improvements would be possible for zinc, copper, brass, bronze, iron, ceramics and glass industries that also have need for a similar continuous sensor system to monitor composition and quality.

该小型企业创新研究（SBIR）第一阶段项目将确定开发高度创新，低成本，高速光电传感器的可行性，该传感器能够在铸造和熔化操作期间连续监测熔融金属合金成分。 该传感器的开发是金属铸造行业和铝行业在其未来行业路线图中确定的最高优先级技术需求之一。 为了有效竞争，美国金属行业必须增加低成本废料的使用，还必须找到提高生产效率的方法。所提出的传感器将获得关键的成分数据比目前的商业方法快数千倍，并将在真实的时间的基础上运行，而不需要将传感器与熔融金属接触。按照这些速度，熔炼车间每天可以额外生产一批金属（即热量），相当于生产率提高15%。价值300亿美元的铝冶炼行业意味着，除了传感器系统本身之外，只需很少或不需要额外的资本投资，就可以实现潜在的45亿美元的产量增加。更短的熔化时间将提高产品质量、减少排放、节约能源和提高产品产量。类似的改进对于锌、铜、黄铜、青铜、铁、陶瓷和玻璃工业也是可能的，这些工业也需要类似的连续传感器系统来监测成分和质量。
