Background technology
Along with the development of China's aluminum i ndustry production technology, the potline current intensity of modern large-scale aluminum electrolytic cell increases just day by day, and according to the description of Faraday's law, when other conditions are equal, the increase with electric current increases by magnetic field.And the electromagnetic force that in magnetic field and electrolyzer that the production electric current of electrolyzer produces, melt Interaction Law of Electric Current produces makes melt cyclical acceleration in groove, cause that liquid aluminum generation is swelled, deflection and fluctuation, even may affect electrolyzer can not normally produce.Therefore in order to realize the stable of electrolyzer magnetic fluid, around groove in busbar require affect electrolyzer administration measure important factor---groove internal magnetic field distribution character (requires that magnetic field value is little, gradient is little) become even more important, and also bus-bar system various piece homogeneous current distribution must be accomplished in the design of bus section (electric physical field), to prevent because electrolyzer anode and cathode distribution of current is uneven, groove internal magnetic field distribution curve is made to produce drift, cause the interface of melt in electrolyzer to be fluctuated, have a strong impact on the normal production of electrolyzer.
Give in the design of roasting groove large-scale, due to engineering needs and reduce investment outlay, usually will consider that two row's electrolyzers produce series as one, and two row's electrolyzers can not at a distance of too far away.Therefore around electrolytic bath in busbar system design, must consider the electric current impact of adjacent row slot, thus make electrolyzer flue side and go out the magneticstrength that aluminium side compensates different, institute's strength of current of walking is also different.With electrolyzer medullary ray for boundary, the left and right sides of electricity input side bus and electricity output side bus is as adopted identical busbar arrangement and specification, field compensation dynamics not only can be caused inadequate, and can Biased flow phenomenon be produced, change the flow condition of magnetic properties and melt in groove, cause electrolyzer stability to wreck, bring high risks to production operation.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of bus configuration method for aluminum electrolysis cell with equidistant current paths is provided, to overcome the electrolyzer magnetic fluid instability that prior art exists, produces Biased flow phenomenon, cause electrolyzer stability to wreck, bring the deficiencies such as high risks to production operation.
