一种稳定状态的非扩散控制的模型已经被推导出来了。它叙述了在电子束或真空自耗电弧精炼过程中,除去熔融合金中稀金属溶质的动力学。虽然这种模型是以二元合金研究出来的,但发现对于在多元废汽车铜中、除去次要成分的理论与实践相吻合。这个模型也能在给定熔炼速度下,要求成品锭中具有某一浓度的溶质时,用来预言熔炼原料中该溶质的浓度所要求的范围。用这个模型计算得出的条件是正确的,并进行了讨论。 A stable non-proliferation control model has been derived. It describes the kinetics of removing rare-metal solutes in molten alloys during electron beam or vacuum consumable arc refining. Although this model was developed based on binary alloys, it was found that the theory and practice of removing secondary constituents in copper for mulit-scale scrap cars are consistent. This model can also be used to predict the extent of solute concentration in a smelting feedstock at a given smelting speed when a desired concentration of solute is desired in the finished ingot. The conditions calculated with this model are correct and discussed.
