Abstract
The present invention relates to an inside lining of aluminium electrolytic bath and its manufacturing method. Said inside lining is characterized by that the lower portion of the negative electrode block of the inside lining of the electrolytic bath is composed of fire-retardant pouring material and dry bulk heat-insulating material partitioned by diaphragm. The low-cost light bulk material is substituted for asbestos board, light brick and alumina powder, fire-retardant pouring material is substituted for fire-brick, so that the cost of the electrolytic bath can be greatly reduced under the condition of that its technical performance is not changed, and its manufacturing method is easy, and can save both labour and time.
Description
A kind of internal lining of aluminium electrolytic bath and preparation method thereof relates to improvement of a kind of cathode lining of electrolytic bath that is used for the electrolysis production metallic aluminium and preparation method thereof.
At present, the aluminium cell of countries in the world, its size no matter, its cathode inner lining mostly is, by charcoal meet, cathode block, sidepiece slot liner, pot shell, cathode steel bar, refractory brick, aluminum oxide, light-weight insulating brick, rock wool thermal baffle and form.The electrolyzer of constructing with above-mentioned materials can satisfy the needs of Aluminium Electrolysis, has obtained using widely.But it is to constructed material quality requirement strictness, and the material price of use is also very expensive, also has the big shortcoming of construction labour intensity.
The objective of the invention is in order to overcome the shortcoming that aluminum current cell lining and preparation method thereof exists, making material to the cell lining selected for use improves, and proposes to have internal lining of aluminium electrolytic bath and the manufacture method thereof that cost of manufacture is low, raw material is easy to get, labour intensity is little.Make its demand that can satisfy Aluminium Electrolysis technology, and low price resource abundance.
The present invention is achieved by the following technical solutions.
A kind of internal lining of aluminium electrolytic bath, comprise that charcoal meets, cathode block, sidepiece slot liner, pot shell, cathode steel bar, it is characterized in that: the cathode block bottom of cell lining is formed with refractory castable with by the dried diffusing insulation material that enriches in electrolyzer pot shell bottom that plastic diaphragms and refractory castable separate.
The making method of cell lining of the present invention, technological process is followed successively by: a. will do the insulation material that looses and add in the pot shell, compacting flattens to designed elevation, b. tamping the plastic diaphragms of doing diffusing insulation material upper berth water-impervious of leveling, c. the refractory castable that stirs is added in the pot shell on plastic diaphragms top shake smash, floating to designed elevation, health is to the intensity that requires, and the cathode block of d. routine, sidepiece slot liner, smashes carbon seam construction working.
It does the insulation material that looses can be industrial cinder, and processing requirement: granularity 0 ~ 30mm, carbon content are less than 10%, and water content is less than 5%.
Refractory castable can be with waste and old refractory brick as main raw material, processing requirement: aggregate 30 ~ 35%, powder 10 ~ 17%, binding agent 15 ~ 17%, water cement ratio 0.35 ~ 0.45.
It does the insulation material bed thickness that looses is 25 ~ 30cm.
The refractory castable bed thickness is 10 ~ 15cm
Because internal lining of aluminium electrolytic bath of the present invention adopts cheap lightweight bulk material industry cinder, replace rock cotton board, light cinder brick and aluminum oxide powder, replaced refractory brick with refractory castable, make electrolyzer guarantee that the cost of manufacture under the constant situation of processing performance reduces greatly, and construction easily, saving of work and time has significantly reduced producer's labour intensity, and extraordinary economic benefit is arranged.
Description of drawings
Fig. 1 is the synoptic diagram of aluminium cell of the present invention,
The invention will be further described below in conjunction with accompanying drawing.
A kind of internal lining of aluminium electrolytic bath comprises that charcoal meets 1, cathode block 2, sidepiece slot liner 3, groove Shell 4, cathode steel bar 5 is characterized in that: cell lining cathode block bottom is with fire-resistant Castable 6 and by enriching at the bottom of pot shell that plastic diaphragms 7 and castable refractory separate The diffusing insulation material 8 of doing in the section forms.
The preparation method of cell lining of the present invention, technical process is followed successively by: a. will do The insulation material that looses adds in the pot shell, and compacting flattens to designed elevation, and b. does the compacting leveling The plastic diaphragms of the insulation material upper berth water-impervious of loosing, c. adds to the castable refractory that stirs In the pot shell on plastic diaphragms top shake smash, floating to designed elevation, health is to the intensity that requires, D. conventional cathode block, sidepiece slot liner, smash carbon seam construction working.
Embodiment
Construction with a 60KA cell lining is an example.
Material:
(1) gas furnace coke slag or boiler cinder are 4800 kilograms, and granularity is 0 ~ 30mm, and carbon content is less than 10%, and water content is less than 5%
(2) refractory concrete uses useless day refractory brick as main raw material, aggregate 30～35%, powder 10～17%, binding agent 15～17%, water cement ratio 0.35 ~ 0.45 with 4788 kilograms.
(3) other common used material.
At first level line around the pot shell inwall, wherein bottom cinder thickness is 30cm, upper strata refractory concrete thickness is 13cm, and cinder is poured in the pot shell, makes it surpass line 2 ~ 3cm and tamps to the position of ruling with rammer compacter.Cinder to compacting checks, with the people upright do not sink thereon and cinder can be not loose, string is moving for qualified.The two-layer light fire brick of laid dry around being close to is covered in cinder with plastic diaphragms and above the light-weight insulating brick.The refractory concrete that has stirred is poured on above the plastic diaphragms.Evenly vibrated 10 minutes with slab tamper, smear with ash again that the position is floating with big face to the layout line, require every meter of roughness less than 5mm.Be laid on plastic film again and carry out health on it.Health finishes, and the inspection surface quality of waking up less than 5mm, is used the aluminum oxide powder cementation of fissures if any crackle, uses the refractory mortar cementation of fissures greater than 5mm.Above-mentioned construction finishes, and can enter conventional constructions such as cathode block group.
Adopt technology construction of the present invention, the spending of having saved the cell lining material has widely alleviated workmen's labour intensity, and benefit is very good.
