This research program aims at generating scientific insights and providing advanced technical solutions for environmental and energy issues, encountered with one of the most important Canadian industries; Aluminum production. The proposed research programme is the continuity of a 5-year CRD programme, jointly supported by NSERC and Alcoa Canada Inc. The objectives of the present program are to identify the sources of energy loss and the parameters affecting thereof, to reveal their mechanisms, and to provide the solutions to increase the anode quality and consistency; all aiming at improving energy efficiency and reducing the environmental impact of the smelting process. To achieve this goal, advanced characterization techniques together with processing the plant data will be used to reveal the constitutive laws governing the material behaviours, either during manufacturing or in the electrolysis cell. Advanced modeling approaches will then be used to simulate the processes, allowing the optimization of material/process/design combinations, resulting in the best process performance. Upon the completion of the program, we expect to have a deep insight on materials properties and their behaviour during manufacturing as well as on process parameters and their influence on the final properties of anode; all allowing a better process control. The numerical models may allow assessing the sensitivity of the process with respect to different material/process parameters, exploring new designs, or performing virtual experiments, otherwise being extremely expensive or technically impossible.

该研究计划旨在产生科学见解，并为加拿大最重要的行业之一铝生产遇到的环境和能源问题提供先进的技术解决方案。拟议的研究计划是由NSERC和Alcoa Canada Inc.联合支持的5年CRD计划的延续。本计划的目标是确定能量损失的来源及其影响参数，揭示其机制，并提供提高阳极质量和一致性的解决方案;所有这些都旨在提高能源效率并减少冶炼过程对环境的影响。为了实现这一目标，先进的表征技术以及处理工厂数据将用于揭示在制造过程中或在电解槽中控制材料行为的本构律。先进的建模方法将用于模拟工艺，从而优化材料/工艺/设计组合，从而实现最佳工艺性能。在项目完成后，我们希望对材料特性及其在制造过程中的行为以及工艺参数及其对阳极最终特性的影响有深入的了解;所有这些都可以更好地进行工艺控制。数值模型可以允许评估工艺相对于不同材料/工艺参数的灵敏度，探索新的设计，或执行虚拟实验，否则非常昂贵或在技术上不可能。
