Abstract:

The work described in this report details the program and the efforts to develop a method by which machine turnings of DU.-0.75 Ti could be recycled. The methods addressed are conversion of machine chips to UF4 co-reduction of chips in the UF4Mg reaction vessels inductoslag remelting vacuum induction remelting, and electron beam remelting. Indications are that the Electron-Beam method holds the greatest degree of potential in that it has the capability of decreasing impurity levels during the melt cycle. However, EB involves a high capital investment and has some technical uncertainties which could only be answered in large scale production. Vacuum induction remelting is also a potentially viable recovery method however, it cannot reduce impurity levels. Indeed, it will contribute to progressively higher carbon levels as generations of material are reclaimed. A specification for an electron-beam vacuum melting and casting furnace has been included as an appendix.
