摘要： Carbon anode blocks for use in the fused salt electrolytic process for producing aluminum, are attached to the studs or spades of an anode suspension means by an adhesive mass which is mechanically strong and a good electrical conductor at least at temperatures between 900.degree. and 1000.degree. C. The studs or spades are preheated to 30.degree.-60.degree. C. and/or the anode blocks at least in the region of the holes for the said studs or spades to 25.degree.-40.degree. C. At the latest 60 seconds after inserting the anode suspension means i.e. after immersion of the studs or spades in the cold-poured adhesive mass, the adhesive mass exceeds a temperature of 25.degree. C. The lowering of the studs or the spades is achieved in the shortest possible time by vibrating the anode blocks and/or the anode suspension means. The stabilizing of this arrangement, at least until the adhesive mix has partly hardened, is achieved preferably by spiking or wedging.

摘要： The invention relates to a storage bunker for a facility which breaks open the solidified crust on an electrolytic cell. The bunker is subdivided into a large container for alumina and a small container for additives. Below the containers are provided a closing-off plate, a dosing facility and a common outlet pipe leading to the break in the crust. When additives are required, these can be fed directly to the small container via the pipe line for supplying alumina. These are then fed to the cell in measured amounts, if desired, mixed with alumina.

摘要： The vertical magnetic force lines in electrolytic reduction cells, in particular in cells for the production of aluminum, are absorbed by a device comprising the steel pot shell and a covering which covers the upper part of the cell and is magnetically connected to the steel shell. The effect of this covering is uniform over the whole of the cell. The covering is made of a magnetic material which conducts well, and it can for example be in the form of a hood, frame or cross bars.

摘要： A chisel for a crust breaking facility for breaking through the solidified crust of electrolyte on an electrolytic cell, in particular a cell for producing aluminum, is such that at least a part of the edge region on the bottom face of the chisel projects out beyond the other regions and is in the form of cutting edges. The bottom face of the chisel features no faces which are inclined outwards and would create outward directed forces as the chisel is forced through the crust.The chisel of the invention allows energy and investment costs to be reduced.

摘要： The invention relates to a chisel alignment unit for a facility for breaking the crust of solidified electrolyte on an electrolytic cell, in particular on a cell for producing aluminum. A mechanically stable alignment box extends from the under side of the chisel in its non-working position to the piston rod. The chisel features at least one vertical alignment surface which is in contact with at least one alignment roll mounted on the alignment box by means of roller bearings. A wiper for removing electrolyte from the chisel is mounted below the alignment rolls and extends over the full width of the alignment surface or surfaces.
