摘要： The electrode arrangement uses vertically oriented electrodes (4) with side wall contacts (7) for an electrothermic smelting furnace (1) for aluminum production. The side wall contacts (7) are radially moveable into the furnace (1) to compensate for wear on the contacts. The side wall contacts (7) can be hollow to allow a slag forming charge to be fed to the furnace (1). The arrengements of contacts at the side wall increases the life of the bottom lining.
