Abstract Scope |
Aluminum smelters produce pure aluminum in reduction cells by the Hall Héroult process, but supply a variety of alloys to their customers. The alloys are produced in the cast house, as desired alloying elements are added to the primary aluminum from the potroom before casting. In this paper the concept of producing titanium master alloys direcly in the aluminum reduction cells is discussed, by feeding titanium oxide to the electrolyte, along with the alumina raw material. The results in this paper are obtained by running electrolysis experiments in a laboratory cell, and the current efficiency for the alloy deposition is estimated. Results for aluminum-silicon and aluminum-manganese alloys are reported in a different paper. |
