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 master alloys containing the desired alloying elements are added to the primay aluminum from the potroom before casting. In this paper the concept of producing silicon or manganese containing master alloys direcly in the aluminum reduction cells, by feeding titanium, silicon or manganese oxides into the electrolyte, along with the alumina raw material. The results in this paper are obtained from a laboratory cell, and the current efficiency for the alloy deposition is estimated. Results for aluminum titanium alloys are reported in a separate paper. |
