During secondary aluminum processing, oxidation of the aluminum in reverberatory furnaces leads to the formation of dross, which contains aluminum in metallic form that is entrapped within its oxide. Among the detrimental effects are loss of aluminum, promotion of metallurgical defects in aluminum products and reduced furnace efficiency, due to the insulation effects of the dross layer. The PI proposes to study the transport processes that lead to dross formation through a numerical and experimental study of the oxidation of molten aluminum alloys in a furnace environment. The goal will be to determine optimal furnace conditions that will minimize the formation of dross. The project is collaborative between the University of Illinois at Chicago and the Gas Technology Institute. Reduction of dross formation has potential for significant increases in energy efficiency and reduction of waste in this industry, which produces 1/3 of the aluminum produced in the United States.

在二次铝加工过程中，铝在反射炉中的氧化导致浮渣的形成，浮渣含有金属形式的铝，其被捕获在其氧化物中。 由于浮渣层的隔热作用，有害影响包括铝的损失、铝产品中冶金缺陷的增加和炉效率的降低。 PI建议通过对熔炉环境中熔融铝合金氧化的数值和实验研究来研究导致浮渣形成的运输过程。我们的目标是确定最佳的炉况，以尽量减少浮渣的形成。 该项目是芝加哥伊利诺伊大学和天然气技术研究所合作的。减少浮渣的形成具有显著提高能源效率和减少该行业废物的潜力，该行业生产美国1/3的铝。
