Abstract
The utility model relates to a large-scale aluminium electrolysis arc boss cathode which comprises a cathode body and a boss. The boss is arranged at the upper end of the cathode body; the boss is in arc transition connection with the cathode body; and the arc radius is 161mm. The utility model designs the connection between the cathode boss and the top surface of the cathode into the arc transition connection, so that the heat impact resistance capacity of the cathode is strengthened; and the lateral surface of the arc boss has good firmness, so that the phenomenon that the boss falls down is avoided and the difficult problem of falling of the cathode boss of a large-scale aluminium electrolysis special-shaped groove is solved. The large-scale aluminium electrolysis arc boss cathode has simple structure, is easy to manufacture, has low manufacturing cost and is convenient to use; the cathode boss can be effectively prevented from falling down; the labor capacity of workers is reduced; a defective groove is prevented from being generated; the production operation is stable; the working voltage of 3.75v is kept; the power consumption per ton of aluminium is reduced into about 12,500kwh; and an excellent energy saving effect is achieved.
Description
Technical field:
The utility model belongs to the special-shaped groove cathode construction of large-scale aluminium electrolysis technical field, is specifically related to a kind of large-scale aluminium electrolysis arc boss negative electrode.
Background technology:
At present, in the special-shaped groove of large-scale aluminium electrolysis the structure formation of negative electrode boss be boss perpendicular to the negative electrode end face, the connection angle of boss and negative electrode end face is the right angle, in roasting process, because temperature distribution is not evenly absolute, there is the temperature spikes/low-points in federation.If cathode construction anti-thermal shock ability very easily causes the interior detail crackle.In start-up course, have violent thermal shock inflation negative electrode boss, the negative electrode boss of existing " right angle " form in the impact process that is heated, has the part boss and comes off.Though be minority, the boss that comes off can cause distribution of current seriously inhomogeneous, and the groove temperature rise is exceedingly fast, the boss dropping situations can be more serious.
The utility model content:
In sum; In order to overcome the deficiency of prior art problem, the utility model provides a kind of large-scale aluminium electrolysis arc boss negative electrode, and it is to connect being designed to arc transition being connected between negative electrode boss and the negative electrode end face; Thereby strengthen the thermal shock resistance of negative electrode; And the boss side surfaces stability of circular arc is good, avoids the generation of boss obscission, has solved the difficult problem that the special-shaped groove negative electrode of large-scale aluminium electrolysis boss comes off.
For solving the problems of the technologies described above, the technical scheme of the utility model is achieved in that
A kind of large-scale aluminium electrolysis arc boss negative electrode, wherein: comprise negative electrode body and boss, boss is arranged on negative electrode body upper end, and boss is connected with negative electrode body arc transition.
Further, the radius of the circular arc that is connected with negative electrode body arc transition of described boss is 161mm.
The beneficial effect of the utility model is:
1, the utility model connects being designed to arc transition being connected between negative electrode boss and the negative electrode end face; Thereby strengthen the thermal shock resistance of negative electrode; And the boss side surfaces stability of circular arc is good; Avoid the generation of boss obscission, solved the difficult problem that the special-shaped groove negative electrode of large-scale aluminium electrolysis boss comes off.
2, simple in structure, easy to manufacture, the low cost of manufacture, easy to use of the utility model; Can effectively stop coming off of negative electrode boss, alleviate workman's labor capacity, prevent the generation of disease groove; Production run is stable; WV remains on 3.75v, and ton aluminium power consumption is reduced in about 12500kwh, reaches good energy-saving effect.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
As shown in Figure 1, a kind of large-scale aluminium electrolysis arc boss negative electrode comprises negative electrode body 1 and boss 2, and boss 2 is arranged on negative electrode body 1 upper end, and boss 2 is connected with negative electrode body 1 arc transition, and its arc radius is 161mm.
The utility model method of use with original negative electrode in use is identical; Boss 2 is connected with negative electrode body 1 arc transition; Strengthened the intensity of boss 2, increased the stressed area that it bears thermal shocking, thereby reach the purpose that prevents that boss 2 from coming off with negative electrode body 1 junction.
Be noted that; The above embodiment is to the explanation of the utility model technical scheme and unrestricted; Other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art; As long as do not exceed the thinking and the scope of the utility model technical scheme, all should be included within the desired interest field of the utility model.
