Problems solved by technology

Due to the limitation of floor area and investment, the row spacing between two (several) rows of electrolytic cells should not be too large. Due to the small row spacing, the rise of the vertical magnetic field will cause large fluctuations in the interface of the melt in the cells. , seriously interfere with the normal production of electrolyzers (especially large ones)

Embodiment Construction

[0009] Embodiments of the present invention: 50% of the electric current flows out from the 27 cathode soft busbars 4 on the power inlet side in the electrolytic cell 1 (the other 50% of the electric current flows out from the cathode soft busbars on the power outlet side), and the electrolytic cell 1 longitudinal axis ( figure 1 Y-axis) as the center, the 3 slot bottom busbars 3 and the slot side busbars 2 near the flue end (right side) are connected with 3 more cathode soft busbars than the 2 slot bottom busbars and the slot side busbars at the aluminum outlet (left side) 4. Make the busbar 3 on the right side of the tank bottom flow in 3 more currents than the left side, so as to realize the current asymmetrical configuration. The three bottom busbars 3 on the right are one more than the two busbars on the left, forming an asymmetric arrangement of the busbars at the bottom of the groove, and the first busbar 5 on the right side close to the Y axis is arranged on the same s...

Abstract

The invention discloses a dissymmetrical bottom generatrix and the current configuration method. The current from the cathode soft generatrix distributes in the electrode in the bottom generatrix and side generatrix centered on the Y axis. The current of bottom generatrix and the side generatrix near the flue (right) is higher than that of the aluminium-outputting terminal. The invention, owing to adopting the dissymmetrical configuration of bottom generatrix and the dissymmetrical configuration of the current, can effectively reduce the magnetic field produced by the electrobath, overcome the influence of the critical magnetic field of the slot, make the magnetic field reach the effects of cutting the peak and filling the flat, reduce the grads of the magnetic field and greatly increase the uniformity of the magnet.

Description

technical field [0001] The invention relates to a method for disposing busbars and currents around a tank in the production of electrolytic aluminum. Background technique [0002] The cell capacity of modern prebaked anode electrolyzers is developing towards large-scale development, and the magnetic field of the electrolytic cell increases with the increase of cell capacity, and its influence is becoming more and more important. Due to the limitation of floor area and investment, the row spacing between two (several) rows of electrolytic cells should not be too large. Due to the small row spacing, the rise of the vertical magnetic field will cause large fluctuations in the interface of the melt in the cells. , Seriously interfere with the normal production of electrolyzers (especially large tanks). Contents of the invention [0003] The purpose of the present invention is to provide an asymmetric tank bottom bus bar configuration and current configuration method, which ca...
