This project is planned to optimize the anode manufacturing technology addressing the challenges related to the effect of anode quality of both the energy consumption in anode manufacturing process and the performance of smelting cells. The challenge of the present anode technology is to produce consistently high quality anodes while dealing with frequent changes in the incoming raw materials and limiting the amount of fuel used for anode baking. The issues encountered with low quality anodes are anode disintegration and outright failure resulting not only in the loss of the energy required for the anode production, but also in the perturbation of the current flow and magnetic field increasing the extra power consumption. 216,000 tons of carbon is annually consumed in excess, in Québec alone. In the modern smelting plans a significant reduction of carbon consumption in electrolytic bath is not possible while the perspective for implementation of inert anodes is not clear either. In time, the improvement of anode quality and production process is most likely the only way to reasonably reduce the excess carbon consumption.

该项目计划优化阳极制造技术，解决与阳极质量对阳极制造过程中的能耗和熔炼槽性能的影响相关的挑战。当前阳极技术的挑战是生产始终如一的高质量阳极。在处理传入原材料的频繁变化并限制阳极烘烤所用燃料量的同时，低质量阳极遇到的问题是阳极解体和彻底失效，不仅导致阳极所需能量的损失。仅在魁北克省，电流和磁场的扰动就导致每年额外消耗 216,000 吨碳。虽然惰性阳极的实施前景尚不明确，但随着时间的推移，阳极质量和生产工艺的改进很可能是合理减少过量碳消耗的唯一途径。
