Description
Technical field：
The present invention is applied to the construction and production of aluminum electrolysis industry various specifications aluminium cell, more particularly to a kind of aluminium electroloysis
The method that slot cathode steel bar is equidistantly segmented.
Background technology：
Aluminium cell is a kind of production equipment of high energy consumption, and production electric current often reaches hundreds thousand of amperes, in production process
It is middle to be inevitably generated larger horizontal current.The generation of horizontal current not only significantly increases vertical magnetic field, but also can draw
The big ups and downs of molten aluminum and the gross distortion of electrolyte and molten aluminum interface are played, the stability of magnetic fluid in slot is influenced, to generate
A large amount of idle power consumption.
Part of horizontal electric current in electrolytic cell being blocked to produce cathode steel bar segmentation, improves current efficiency.But at present
It does not seek unity of standard to cathode steel bar segmentation in industry, segmentation is random, therefore inhibits limited to horizontal current, and current efficiency improves
Unobvious.In extreme case or even meeting occurred level current break, the bad phenomenon for producing the influences production such as unstable.
Invention content：
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, and provide a kind of aluminum cell cathode steel bar
Equidistant segmentation method, this method can solve the segmentation of existing rod iron it is unreasonable caused by a series of problems.
As above design, the technical scheme is that：A kind of equidistant segmentation method of aluminum cell cathode steel bar, feature exist
In：Keep the spacing between two groups of anode carbon blocks of segmentation spacing and aluminium cell between two sections of cathode steel bars equal, and makes two sections
Cathode steel bar is symmetrical with the center line of cell cathode carbon block；Segmentation spacing between above-mentioned two sections of cathode steel bars and aluminium electroloysis
The deviation of spacing between two groups of anode carbon blocks of slot controls within 1%；Above-mentioned two sections of cathode steel bars are symmetrical with aluminium cell the moon
The center line of pole carbon block, position deviation control within 2%.
The present invention has the advantage that and good effect：
1, the present invention gets the segmentation distance of cathode steel bar wide with aluminium electrolysis cell anode carbon block spacing, makes production electric current
It can keep vertical when flowing to cathode from anode, generate smaller horizontal current, improve current efficiency.
2, cathode steel bar fragmentation technique of the invention is easy to operate, it is not necessary to by complicated design and calculating.
3, applied widely present invention can apply to different size, the aluminium cell of different groove profiles.
4, the horizontal current in can producing electrolytic cell using the present invention reduces by 30% or so, can effectively optimize electric current point
Cloth improves current efficiency, reduces idle power consumption, and energy-saving effect is apparent.
Description of the drawings：
Fig. 1 is the equidistant stepwise schematic views of aluminum cell cathode steel bar.
In figure：Between 1- anode carbon blocks, 2- anode carbon blocks spacing, 3- cathode carbon pieces, 4- cathode steel bars, the segmentation of 5 cathode steel bars
Away from, 6- aluminium cell center lines.
Specific implementation mode：
The present invention is illustrated below in conjunction with the accompanying drawings.
Same specification with the anode carbon block spacing (2) (i.e. L1) between two groups of anode carbon blocks (1) of groove profile aluminium cell is solid
Fixed constant, the cathode of electrolytic cell is assembled by cathode carbon pieces (3) and cathode steel bar (4).When assembling cathode steel bar (4), adjust
Segmentation spacing (5) (i.e. L2) between whole two sections of cathode steel bars, is allowed to equal (i.e. with two groups anode carbon block spacing (2) (i.e. L1)
L1=L2), and two sections of cathode steel bars (4) is made to be symmetrical with the centers of cathode carbon pieces (3).
The equidistant fragmentation technique of the present invention must be strictly controlled there are two data：
1, cathode steel bar segmentation spacing (5) (i.e. L2) and the deviation of two groups of anode carbon block spacing (2) (i.e. L1) must control
Within 1%, i.e. L2=(0.99~1.01) L1.
2, the position of cathode steel bar segmentation spacing (5) (i.e. L2).Center when must assure that its assembling with cathode carbon pieces (3)
Line (6) keeps Striking symmetry, position deviation to control within 2% (0.02*L2), to ensure spacing (5) (i.e. L2) after installing
It with spacing (2) (i.e. L1) stringent centering, keeps vertical when production electric current being enable to flow to cathode from anode, generates smaller level
Electric current improves current efficiency.
Using the equidistant fragmentation technique of the present invention compared to other segmentation methods, surveys in production, produce voltage
Fluctuation, which reduces nearly 50%, horizontal current, reduces by 30% or so, current stabilization, energy-saving effect clearly.
The aluminium cell of different current strength, different size, different groove profiles, anode carbon block spacing (2) (i.e. L1) is not
It is identical, but the anode carbon block spacing (2) (i.e. L1) of each specification electrolytic cell is fixed.With the application of the invention, in different rule
Lattice, different groove profile electrolytic cell cathode steel bar assembling when, cathode steel bar is segmented spacing (5) (i.e. L2) need to be according to the sun of the slot
Pole carbon block spacing (2) (i.e. L1) adjusts, it is not necessary to by complicated calculating and experiment.Therefore the equidistant fragmentation technique of the present invention
The cathode steel bar assembling of all aluminium cells is can be applied to, it is easy to operate, applied widely.
