Abstract: The present invention relates to a method for casting of molten electrolyte tapped from electrolytic cells for production of aluminium. Molten electrolyte is continuously supplied to one end of a rotating drum which is partly filled with particulate solidified electrolyte whereby the molten electrolyte solidifies in the form of particles. The solidified particles are continuously discharged through a discharge opening in the other end of the drum, said discharge opening being at a lower level that the inlet opening for molten electrolyte.

Abstract: The present invention relates to a method for closing and cooling of the top of a Soderberganode for use in connection with electrolytic production of aluminium, which anode is equipped with an anode casing and vertical contact bolts for holding and for conducting operating current to the anode and where the top of the anode casing is equipped with at least one cover having openings for the contact bolts and at least one off-gas opening. The amount of gas removed from the top of the anode through the off-gas opening is regulated in such a way that a sufficient diminished pressure is provided on the top of the anode that surrounding air will flow through air gaps arranged between the cover and each of the contact bolts in such an amount that gas from the top of the anode does not escape through the air gaps and to keep the temperature of the top of the anode casing below a preset temperature. The present invention further relates to an arrangement for closing and cooling of the top of a Soderberganode used in connection with electrolytic production of aluminium where air gaps between 1 and 10 mm are arranged between each of the contact bolts and openings in the cover in order to allow flow of surrounding air in through the air gaps.
