Method and arrangement for closing and cooling the top of an anode

The present invention relates to an arrangement for closing the top of a Soderberganode used in an electrolytic cell for production of aluminum. The anode comprises an anode casing and vertical contact bolts for holding and for conducting electric current to the anode. The top of the anode is closed by means of at least one central cover having openings for the contact bolts and at least one side cover which can be opened in order to charge anode paste to the anode.

Arrangement for closing the top of a Soderberg anode in an electrolytic

The present invention relates to an arrangement for gas collection in electrolytic aluminium reduction furnaces equipped with Soderberg anode. The arrangement comprises a plurality of liftable cover plates 8-11 which cover the complete area between the sidewalls of the furnace and the anode casing 2. The cover plates 8-11 are gas tight sealed against the circumference of the anode casing 2 and against the furnace sidewalls 7. The cover plates 8-11 are on their upper side equipped with a plurality of ribs 12. A channel 13 comprising of a lower plate 14, and inclined plate 15 and an upper plate 16 is inserted in recesses in the ribs 12.
