Abstract
Method and arrangement for removing a gas cushion formed at the anode in an electrolytic cell for the production of aluminum by electrolysis of aluminum oxide dissolved in molten cryolite. There is employed a tubular lance which through a flexible hose is connected to a source of pressurized gas, and which is with its mouth adapted to be introduced towards the gas cushion in order to have this blown away. As the source of gas there is employed an exhaust gas system of a combustion engine located in a movable machine.
