Embodiment Construction

[0013] Embodiment of the present invention: on the power supply side of the electrolyzer, the method of feeding power at 6 points on the large surface is adopted, and 6 column busbars 1 are arranged on the power supply side, and the 6 column busbars 1 are all distributed in equal current proportions. The side busbar 2 and the outlet-side busbar 5 are symmetrically arranged with multi-layer busbars, and the outlet-side busbar 5 is folded horizontally or vertically to increase the current path to the busbar of the downstream slot column to achieve the purpose of current balance, such as Figure 1 shows. The left end of the electrolytic cell is the flue end, and the right end is the aluminum outlet end. There are tank-side busbars 3 at both ends. In order to better compensate the magnetic field of the melt in the tank, the tank-side busbar 3 adopts a stepped configuration, that is, by The elevation from side A to the center of the cell is low, and the elevation from the center of ...

Abstract

The invention discloses a cathode bus bar wire structure of 350KA aluminum electro-bath that adopts the method of large face six pointers input electricity, and 6 column bus bar wires are set at the electricity inputting side. The electricity input side bus bar wire and the electricity output side bus bar wire adopt multilayer bus bar wire symmetrically collocation. The bus bar wire beside the electro-bath adopts stair collocation. And the compensation bus bar wire under the bottom of electro-bath adopts the collocation method of lower than the AB girder of the groove to pass through the bottom. The cathode bus bar wire and the cathode steel stick adopt cathode steel stick compressor to join together. Others adopt common location and connection. The invention successfully solves the problem of equality and stability of the melting magnetism in the large aluminum electro-bath.

Description

Technical field: [0001] The invention relates to a method for disposing cathode busbars for extra-large prebaked electrolytic cells. technical background: [0002] With the continuous improvement of aluminum electrolytic cell design technology and process operation level, the working current of modern large-scale aluminum electrolytic cell is increasing day by day, and the magnetic field generated by its current-carrying busbar and melt current has more and more influence on the production and stable operation of the electrolytic cell. stand out. Due to the electromagnetic force generated by the interaction between the magnetic field and the melt current, the melt circulation in the tank is accelerated, causing the aluminum liquid level to rise, deflect and fluctuate, and may even affect the normal production of the electrolytic tank. Therefore, when designing a high-efficiency large-scale electrolytic cell, it is necessary to consider weakening and controlling the magnetic...
