Description
Technical field
The utility model belongs to technical field of aluminum electrolysis, more particularly to a kind of variable cross-section rod iron used for aluminium electrolysis.
Background technology
With the further investigation of aluminium electrolytic industry technology, the stability of electrolytic cell turns into big-and-middle-sized design of electrolysis cells and life
More and more important problem in production, and stability is determined by magnetic field, electric field and horizontal current collective effect.
Horizontal current is to influence aluminium cell production to stablize one of worst factor in aluminium liquid, because the level in aluminium liquid
Electric current interacts with vertical magnetic field, produces electromagnetic force, causes the interface of aluminium liquid to swell deformation.Horizontal current is excessive, to electrolysis
The stability of groove, technical-economic index all have a great impact.In addition, horizontal current can accelerate melt flow, stove side is washed away,
Burner hearth is destroyed, triggers Pot Lining damaged, influences groove life.Horizontal current is to the stability of electrolytic cell, current efficiency, groove life
Influence is very big, therefore we must try every possible means to suppress the horizontal current of electrolytic cell, analysis level electric current in design and producing
The origin cause of formation and Retraining Measures, to design of electrolysis cells and production have very important meaning.
The content of the invention
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided a kind of variable cross-section rod iron used for aluminium electrolysis, solution
Certainly common double rod iron structure in the course of the work existing hot-spot, easily form larger thermal stress, certain safety to be present hidden
The technical problem of trouble.
The utility model is achieved through the following technical solutions：
A kind of variable cross-section rod iron used for aluminium electrolysis, wherein：Including installation portion, transition connection portion and extension, the installation portion
Transition connection portion one end is located at, the extension is located at the transition connection portion other end, and the height of the installation portion is more than extension
Height；
The upper surface of the installation portion and extension is horizontal plane, and the upper surface of the transition connection portion is inclined-plane, institute
State and connected between the upper surface of installation portion and the upper surface of extension by the upper surface transition of transition connection portion, the transition connects
Angle between the upper surface of socket part and horizontal plane is 2 degree.
The utility model changes common double rod iron section phase by the setting of installation portion, transition connection portion and extension
Same structure, avoids the excessive situation of local current densities, reduces horizontal current, improve the stability of electrolytic cell.
Compared with prior art, the utility model has the advantages that metal wave is small, stability is high, power consumption is small.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 be in Fig. 1 I at close-up schematic view；
Fig. 3 is the horizontal current distribution map of 500kA aluminium cell difference rod iron structures.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of variable cross-section rod iron used for aluminium electrolysis in the present embodiment, wherein：Including installation portion 1, mistake
Connecting portion 2 and extension 3 are crossed, the installation portion 1 is located at the one end of transition connection portion 2, and the extension 3 is located at transition connection portion 2
The other end, the height of the installation portion 1 are more than the height of extension 3；
The upper surface of the installation portion 1 and extension 3 is horizontal plane, and the upper surface of the transition connection portion 2 is inclined-plane,
Connected between the upper surface of the installation portion 1 and the upper surface of extension 3 by the upper surface transition of transition connection portion 2, it is described
Angle between the upper surface of transition connection portion 2 and horizontal plane is 2 degree.
The installation portion 1 and transition connection portion 2 are arranged in cathode carbon pieces groove, and the extension 3 is arranged at outside groove
For welded cathode bus.
As shown in figure 3, the horizontal current distribution under analysis two kinds of different rod iron structures of contrast is understood, variable cross-section rod iron is taken
Structure, the horizontal current of Y-direction significantly reduce, its peak value 214A/m2.Average is 415A/m2, its overall distribution curve also becomes
It is more smooth；It is 575A/m to take its horizontal current peak value of the structure of 70cm common double rod irons2, average 501A/m2.No matter peak
Value or average, variable cross-section rod iron technology have certain advantage.
The utility model can be embodied without departing from the spiritual or substantive of invention in a variety of forms, so should manage
Solution, above-described embodiment is not limited to foregoing details, and should widely be explained in claim limited range, therefore falls into
Claim or change in its equivalent scope and remodeling all should be claim and covered.
