Abstract
The invention relates to method and apparatus for lining the cathode of the electrolytic cell. The method comprises filling the cell's shell with powder material, leveling it with a rack, covering the fill material with a dust-proof film, and compaction. Compaction is performed in two stages: preliminary static and final dynamic treatment by consequent movement of static and dynamic work tools of compaction along the longitudinal axis of the cathode of the electrolytic cell through a cushion, which is made of at least 2 layers: a lower layer, which prevents pushing powder material forward in the direction of travel, and an upper layer, which provides for a coupling between the cushion and the static work tool. Static treatment unit of the apparatus, designed in the form of a roller with a drive, is connected to a dynamic treatment unit with a vibratory exciter by means of elastic elements.
