Abstract
Изобретение относитс к области электролиза алюмини , в частности к устройствам подин электролизеров. Цель изобретени - повышение срока службы подины за счет снижени образовани трещин в межблочных соединени х. Дл этого между подовыми блоками 1, подовыми и бортовыми блоками ввод т углеродистые элементы 3, а остальное пространство между блоками заполн ют углеродистой массой, котора , обжига сь вместе с блоками, образует плотное соединение, не наруша целостности подовых блоков, особенно в углах. 2 ил.The invention relates to the field of aluminum electrolysis, in particular, to the devices of the bottom electrolysis cells. The purpose of the invention is to increase the service life of the hearth by reducing the formation of cracks in the interconnects. To do this, carbon elements 3 are inserted between the bottom blocks 1, bottom blocks and side blocks, and the rest of the space between the blocks is filled with carbon mass, which, after firing together with the blocks, forms a tight joint without disturbing the integrity of the bottom blocks, especially in the corners. 2 Il.
