Technical field
The present invention relates to the control technique of a kind of aluminium electroloysis, particularly to the regular burner hearth of a kind of aluminium cell
Control method.
Background technology
The burner hearth of Hall-Ai Lu aluminium cell is the important component part of electrolysis bath, is whole electrolytic process
At all.It passes through solidification and the fusing of electrolyte crust, can automatically adjust heat flat within the specific limits
Weighing apparatus.When heat income is less than heat expenditure, electrolyzer temperature reduces, and electrolyte starts solidification, is formed new
Burner hearth, and process of setting are released amount of heat, slows down the amplitude that electrolyzer temperature reduces, be finally reached
New thermal balance.Otherwise, when the Re Shou National People's Congress pays in heat, electrolyzer temperature raises, and has solidified formation
The electrolyte melting of stove side, forms new burner hearth, and absorbs amount of heat in fusion process, slow down electrolysis
The amplitude that bath temperature degree raises, the most also reaches new thermal balance.
Whether regular electrolysis bath burner hearth is will directly decide the production target of this electrolysis bath.Regular burner hearth energy
Ensure electrolysis bath stable operation, can effectively protect artificial stretching one's legs and side wall carbon block. prevent them from aoxidizing
Breakage, reduces the generation of sick groove；And irregular burner hearth makes electrolysis bath operation conditions be deteriorated, show themselves in that
Current distribution in anode is uneven, and voltage swing is many, and current efficiency is relatively low, thus shortens the use of electrolysis bath
Life-span.
At present, in the running of electrolysis bath, a lot of electrolysis baths are formed without regular chamber structure, and
Owing to electrolysis process is more complicated, affect the many factors of chamber structure, the most also do not have in actual production
There is a kind of control method that the burner hearth of electrolysis bath can be made to form ordered structure.
Summary of the invention
It is an object of the invention to overcome disadvantage mentioned above, it is provided that the control method of the regular burner hearth of a kind of aluminium cell,
Improve the uniformity of CURRENT DISTRIBUTION in electrolysis bath, improve current efficiency and the stability of electrolysis bath.
The technical scheme is that
A kind of control method of the regular burner hearth of aluminium cell, the step of described control method is as follows:
A, the air quantity of regulation aluminium cell gas fume valve: reduce the aperture of the gas fume valve of electrolysis bath, by aluminum
The gas fume valve of electrolysis bath regulates to 10-70 degree；
B, the temperature controlling aluminium cell and the degree of superheat: the addition of aluminium fluoride in regulation electrolyte, control
Molecular proportion is 2.4-2.6, and electrolyzer temperature controls at 958-968 DEG C, and the degree of superheat is 10-15 DEG C, regulation
Time continues 15-60 days；
The aperture of c, again regulation aluminium cell gas fume valve: after step b is carried out 20-30 days, increase cigarette
The aperture of air valve, regulates described gas fume valve to 30-80 degree；
D, adjust voltage and the aluminum level of aluminium cell: aluminium cell Control of Voltage 3.76-3.95V it
Between, aluminum horizontal adjustment to 23-28cm；
E, the temperature readjusting aluminium cell and the degree of superheat: the molecular proportion of regulation aluminium cell is
2.3-2.4, the temperature controlling aluminium cell is 950-960 DEG C, and the degree of superheat is 6-10 DEG C.
Preferably, in described step d, aluminium cell Control of Voltage is in 3.76-3.80V, aluminum horizontal adjustment
To 23-25cm.
Preferably, in described step d, aluminium cell Control of Voltage is in 3.80-3.85V, aluminum horizontal adjustment

To 25-27cm.
Preferably, in described step d, aluminium cell Control of Voltage is in 3.90-3.95V, aluminum horizontal adjustment
To 26-28cm.
Preferably, in described step c, the governing speed of gas fume valve is every 5 days regulation 1-5 degree.
Preferably, after described step b is carried out 5-10 days, artificial treatment electrolysis bath inner corner portion is stretched one's legs.
Preferably, stretch one's legs described in process operating mode be corner anode current be 2.5mV.
The control method of the regular burner hearth of aluminium cell that the present invention provides, has the advantage that
Using the control method of the regular burner hearth of present invention offer, the electrolysis bath making operation can be at 30-60
The chamber structure that it formation is regular, thus the uniformity of CURRENT DISTRIBUTION in improving electrolysis bath, make current efficiency
Increasing to 92-95%, anode effect coefficient is reduced to less than 0.02, and voltage swing is reduced to less than 5 minutes.
In the control method of regular burner hearth, first adjust the gas fume valve of electrolysis bath, make gas fume valve
Aperture is less than normal, and electrolysis bath heat expenditure reduces, and the temperature in electrolysis bath raises, by adding of regulation aluminium fluoride
Enter amount, molecular proportion in regulating tank, make the temperature of electrolysis bath control at 958-968 DEG C, the degree of superheat controls
10-15 DEG C, electrolysis bath keeps the most higher temperature and the degree of superheat, before ensureing that efficiency losses is little
Put, position irregular in burner hearth being melted quickly, make the burner hearth in electrolysis bath gradually form regular
Structure.
After burner hearth gradually forms ordered structure, again adjust the gas fume valve of electrolysis bath, make gas fume valve
Aperture is gradually increased, and electrolysis bath heat expenditure increases, and the temperature in electrolysis bath starts to be gradually lowered；By adjusting
Whole bath voltage and the value of aluminum level, divide in making voltage and the horizontal Proper Match of aluminum, and regulating electrolytic tank
Son than, electrolyzer temperature, make electrolysis bath at the degree of superheat controls to be 6-10 DEG C, the stable operation long period,
Make liquid electrolyte on the basis of regular burner hearth, slowly penetrate into stove side internal, be filled in solid electrolytic
In the stove side gap that matter is formed, forming capacity of resisting disturbance strong, strong regular of heat shock resistance stablizes burner hearth.Treat
Regular stablize after burner hearth formed, each technological parameter of slow regulating electrolytic tank so that it is be mutually matched, electrolysis
Homogeneous current distribution in groove, good stability, current efficiency is high.
