Method for configuring bus bar of aluminum electrolytic bath

Abstract

The invention discloses a method for configuring a bus bar of an aluminum electrolytic bath. The current in the electrolytic bath flows out from a power-in bus bar through a negative soft bus bar (1) to a zigzag bottom bus bar (3), a bottom through bus bar (4) and a side bus bar (5) respectively though a power-in negative bus bar, then enters a side bus bar through the zigzag bottom bus bar (3) and finally enters 4 pillar bus bars (7) of a downstream bath through the bottom through bus bar (4) and the side bus bar (5) respectively; and the current also flows out from a power-out bus bar through the negative soft bus bar (1) to the 4 pillar bus bars (7) of the downstream bath through a power-out negative bus bar (6). In the method, in an overall consideration of technology and economy and based on the configuration form of negative and positive pole numbers of the whole bath and the power-in way, a scheme for the magnetic field compensation of large aluminum electrolytic baths is more rationally designed to achieve a good magnetic field compensation effect and save the using amount of the bus bar around the baths so as to overcome the adverse factors in the conventional electrolytic baths.

Description

technical field [0001] The invention relates to the technical field of a current supply device for an aluminum electrolytic cell, in particular to a method for arranging bus current around a large aluminum electrolytic cell. Background technique [0002] With the development of my country's aluminum industry production technology, the current intensity of the series of modern large-scale aluminum electrolytic cells is increasing day by day, and the electromagnetic force generated by the interaction between the magnetic field generated by the production current of the electrolytic cell and the melt current in the electrolytic cell makes the melt in the cell The systemic circulation is accelerated, causing the aluminum liquid level to rise, deflect and fluctuate, and may even affect the normal production of the electrolytic cell. Therefore, in order to achieve the stability of the ferrofluid in the electrolytic cell, it is more important to design the busbar around the cell, wh...

Problems solved by technology

If the original busbar design around the tank is adopted, it cannot well meet the design requirements of the electrolytic tank magnetic field, which will cause the local magnetic field of the electrolytic tank to be too large and the stability of the tank is not good, which not only brings great harm to the production operation, but also cannot produce good results. economic benefits
