Abstract
The covering sytem for a conventional fused salt electrolytic cell for the reduction of aluminum oxide to metallic aluminum comprises individual lids (4) butting onto each other at the sides and inclined downwards from the anode beam (1) to the edges (5) of the long sides of the reduction pot. The lids (4) are provided with a support (6) which rests on a rail (13) when the anode beam is in the raised position. As the anode beam (1) is lowered, the lids (4) slide over the long edges (5) of the pot, until they are supported by the stops (7) mounted on the lower third part of the lid (4). On lowering the beam (1) further, the supports (6) slide on the anode beam (1). The anode rods (2) are enclosed at the sides by the lids (4).
