Production of aluminum-silicon alloys in an electrolytic cell

Abstract From the Canadian patent

There is disclosed a method of achieving improved operation of aluminum reduction cells being used to produce aluminum-silicon alloys. The method includes the steps of feeding alumina and silica into a molten salt bath of the cell and passing electric current through the bath wherein, the feeding of alumina comprises introducing approximately equal incremental amounts of alumina effective in the aggregate to supply the cell's alumina requirements the, feeding of silica comprises introducing approximately equal incremental amounts of silica effective in the aggregate to supply the cell's corresponding requirements of silica to produce an alloy of the desired silicon content and these, …
