摘要： The invention concerns a detachable assembly for spot feeding alumina to a tank for the production of aluminum. A fixed hopper is made integral with horizontal metal girders which form at least part of its side walls. The hopper is provided with a bottom aperture for discharge of alumina therethrough. An impervious metal case is positioned vertically in said hopper with the upper part of the case open and substantially at the level of the upper part of the hopper. The case has two substantially parallel vertical branches, the first branch opening, at its lower portion, outside the hopper, and the second branch opening, at its lower portion, inside the hopper, in the immediate vicinity and on the axis of the aperture for the discharge of alumina.

摘要： An apparatus for the precise adjustment of the anode plane of a cell for the production of aluminum by electrolysis of alumina dissolved in the molten cryolite of which the anodic system comprises a plurality of prebaked anodes arranged in two parallel lines and provided with suspension rods connected electrically to an anode bus bar which permits the positive intake of current. The apparatus comprises: a fixed gantry formed by at least one rigid horizontal beam provided with supports at its ends; a collective frame formed by two rigid horizontal elements each corresponding to a line of anodes, each supported by the fixed gantry via an assembly of rods and of levers which enable the two rigid elements to travel relative to the gantry in a rising or descending direction, while remaining horizontal; a means for controlling each assembly of rods and levers which is separate but can be coupled; a plurality of jacks for individually controlling the rise or descent of the anodes which are connected on the one hand to the collective frame and on the other hand to a plurality of small individual frames, electrical and mechanical connections between the small individual frames and the anode suspension frames; and the bus bars and the small individual frames being electrically connected.

摘要： A process and apparatus for controlling the rate of introduction and the content of alumina to a tank for the production of aluminium by the electrolysis of dissolved alumina in a cryolite-base bath, the upper part of which forms a solidified crust, and wherein the alumina content is maintained within a narrow range, of between 1% and 3.5%, wherein the alumina is introduced directly into the molten cryolite bath by way of at least one opening which is kept open in the solidified crust and the rate at which the alumina is introduced is modulated relative to variations in the internal resistance of the tank during predetermined periods of time, with alternation of the cycles of introducing alumina at a slower rate and at a faster rate than the rate corresponding to normal consumption within the tank.
