Latest Patents

Kvalavag holds a patent for a "Point feeder for aluminium electrolysis cell." This invention involves a feeder designed to supply additives such as aluminium oxide or fluoride to aluminium electrolysis cells. The system allows for the precise feeding of these additives into the electrolytic bath through a hole in the bath crust, utilizing a pipe stub. The hole is created using a crust breaker equipped with a crow bar connected to a piston/cylinder device. The point feeder features a housing with an upper part that is partially open to the surroundings and a lower part that is sealed from the crust and external environment. The crow bar is guided through a bushing between the upper and lower parts, while the pipe is strategically attached to the lower part or positioned beneath it, such as on the gas apron of the anode casing in a Soederberg cell.
