摘　　要：在金属钛材加工等生产过程中会产生大量废钛,导致钛金属利用率并不高。同时钛金属产业有较大缺口,因此废钛金属的回收利用尤为重要。熔盐电解法具有成本低、绿色环保、产品纯度高等优点,基于熔盐电解工艺的切削废钛处置不仅满足“低碳”工业变革,还产出高纯钛,实现废钛屑高值利用。经研究以热力学计算为基础,结合熔盐电化学行为测试,1.9 V熔盐电解效率最佳,达80%,实现主体钛金属与杂质元素的定向分离,产品纯度达4N5。In the process of titanium processing,a large amount of waste titanium will be produced,resulting in a low utilization rate of titanium metal.At the same time,there is a large gap in the titanium industry,so the recycling of waste titanium is particularly important.Molten salt electrolysis process can produce and refine a variety of metals,which has the advantages of low cost,green environmental protection and high product purity.In view of this,the treatment of cutting waste titanium based on molten salt electrolysis process not only meets the"low-carbon"industrial change,but also produces high-purity titanium and realizes the high-value utilization of waste titanium chips.Based on thermodynamic calculation and electrochemical behavior test of molten salt,the electrolysis efficiency of 1.9 V molten salt is the best,up to 80%,which realizes the directional separation of main titanium metal and impurity elements,and the product purity is up to 4N5.
