Description
Technical field
The present invention relates to electrolytic cell service technique field, and more particularly to a kind of method for repairing and mending of electrolytic cell sideways furnace wall.
Background technology
In the past, electrolytic cell local damage or runout do not have any remedial measure, but carry out unplanned property overhaul in advance,
This mode has the following disadvantages：Average groove age can substantially be shortened；Increase ton aluminium cost.Later, in order to avoid unnecessary big
Repair the influence brought to electrolytic cell, aluminium electroloysis industry is initially formed various carries out light maintenance to electrolytic cell local damage or other problemses
Method, but all do not form more specification, reliable technology, the effect of repairing is also not obvious enough.
Wherein, the phenomenon lifted on silica brick occurs in production early stage for partial electrolyte groove, due to no side in being produced in the later stage
The protection of portion silica brick, when the consumption of local stove side is thinning, sidepiece pot shell rod iron is stable to be risen, can there is a possibility that it is breakdown, because
The local light maintenance of this sideways furnace wall is necessary.Currently the local minor repair method of counter-lateral quadrents stove side is：First, it is determined that needing repairing
Position, and materials block presses big face；Secondly, sidepiece is cleaned out；Then, the position for needing to repair is repaired with silica brick, in repairing
Before, if aluminium water is too high, in addition it is also necessary to first extract aluminium water out a part.The shortcoming that this method is present is as follows：
When the 1st, pressing big face, material block can enter anode bottom, be likely to result in the long bag of anode；When the 2nd, being repaired with silica brick counter-lateral quadrents,
Gap occurs in the side seam of sideways furnace wall and bottom, and when sideways furnace wall consumes thinning, aluminium water can be entered among gap, and then is made
Heat emission hole temperature is raised again, influences the stationarity of electrolytic cell；3rd, aluminium water is taken out if desired, then can influence the normal fortune of electrolytic cell
OK.
The content of the invention
It is an object of the invention to provide a kind of method for repairing and mending of electrolytic cell sideways furnace wall, the method repair efficiency is good, no
Gap can be produced, and aluminium water need not be taken out, the normal operation of electrolytic cell is not influenceed.
The present invention is solved its technical problem and realized using following technical scheme.
The present invention proposes a kind of method for repairing and mending of electrolytic cell sideways furnace wall, and it comprises the following steps：
Electrolyte is adjusted to 15~16cm, the negative electrode of lower section will be dropped down onto under the corresponding anode of sideways furnace wall to be repaired
On；
Materials block presses big face, and the pot shell of aluminium water and sideways furnace wall is separated；
Silica brick remaining on sideways furnace wall is cleared up, and model is made with aluminium sheet, is formed between the shell surface and pot shell of crust layer
The gap of position to be repaired is surrounded together；
Made firm by ramming with to be repaired position of the carbon paste in gap, until by position to be repaired make firm by ramming to the same water of other silica bricks
Prosposition is put；
Lift anode.
Further, in present pre-ferred embodiments, before the anode of whereabouts, anode fixture is opened, with insulation board by sun
Pole guide rod and bus are separated, and are lifted after anode, close anode fixture, take out insulation board.
Further, in present pre-ferred embodiments, repairing the specific method of position to be repaired is：With 65~70 DEG C
Carbon paste is made firm by ramming in position to be repaired, is often made the carbon paste layer to form a 1.5~3cm of thickness firm by ramming, is spread coal tar on carbon paste layer, then smash
Gu next layer of carbon paste layer, until by position to be repaired make firm by ramming to other silica brick same level positions.
Further, in present pre-ferred embodiments, sidepiece silica brick includes pot shell and the silica brick layer in pot shell, treats
Repair position and be located at silica brick layer.
Further, in present pre-ferred embodiments, the width in gap is identical with the thickness of silica brick layer, be 10~
15cm。
Further, in present pre-ferred embodiments, the method for model is made of aluminium sheet is：Aluminium sheet is inserted into crust layer
Between shell surface and silica brick layer, and laminating silica brick layer, gap is formed between aluminium sheet and pot shell.
Further, in present pre-ferred embodiments, position to be repaired is completed after repairing, pressure is welded on silica brick layer
Plate.
Further, in present pre-ferred embodiments, anode is lifted to initial position, with rake by the bottom of anode
The palm strikes off.
Further, in present pre-ferred embodiments, dry completing the repairing position after repairing.
Further, in present pre-ferred embodiments, obtained after material block crust layer is broken.
The beneficial effect of the method for repairing and mending of the electrolytic cell sideways furnace wall of the embodiment of the present invention is：The method for repairing and mending is first by electricity
Solution matter is adjusted to 15~16cm, by the negative electrode that lower section is dropped down onto under the corresponding anode of sideways furnace wall to be repaired；Materials block pressure is big
Face, the pot shell of aluminium water and sideways furnace wall is separated；Silica brick remaining on sideways furnace wall is cleared up, and model is made with aluminium sheet, in crust
The shell surface of layer surrounds the gap of position to be repaired together with being formed between pot shell；Smash with to be repaired position of the carbon paste in gap
Gu, until by position to be repaired make firm by ramming to other silica brick same level positions；Finally lift anode.This method repair efficiency
It is good, gap will not be produced, and aluminium water need not be taken out, the normal operation of electrolytic cell is not influenceed.

It is 10~15cm.
S4, made firm by ramming with to be repaired position of the carbon paste in gap, until position to be repaired is made firm by ramming to same with other silica bricks
One horizontal level, is completed after repairing, and pressing plate is welded on new silica brick layer 171, can also be blown completing the repairing position after repairing
Wind, to accelerate the formation of new sideways furnace wall 170.
Repairing the specific method of position to be repaired is：Made firm by ramming with 65~70 DEG C of carbon pastes in position to be repaired, often make shape firm by ramming
Into the carbon paste layer of a 1.5~3cm of thickness, coal tar is spread on carbon paste layer, then makes next layer of carbon paste layer firm by ramming, until by cover to be repaired
Put make firm by ramming to other silica brick same level positions.
It is S5, shown in Figure 4, lift after anode 140 to initial position, struck off the bottom of anode 140 with rake, in sun
The top surrounding sprinkling alumina powder of pole 140, forms heat-insulation layer 150, accordingly, closes anode fixture, take out insulation board 181, should
Anode 140 can normal power-up use.
In the method for repairing and mending of the electrolytic cell sideways furnace wall of the embodiment of the present invention：Using the to be repaired of carbon paste counter-lateral quadrents stove side 170
Cover, which is put, to be repaired, and carbon paste after making firm by ramming layer is through oversintering, hardness rise, and silica brick with surrounding, pot shell 172 is seamless, warp
Cross stop plow stove find carbon paste layer sintering it is blocking, without crackle, illustrate that repair efficiency is good.Sideways furnace wall 170 after repairing
Temperature can effectively reduce, and the duration is long, by it was verified that the sideways furnace wall 170 after repairing can at least be maintained 1 year
Service life.
The method for repairing and mending of the embodiment of the present invention can also farthest reduce the influence to electrolytic cell, during repairing, without taking out
Aluminium water 120, it is only necessary to suspend the corresponding energization work of anode 140 in position to be repaired, other anodes 140 in electrolytic cell are not influenceed
After the completion of normal work, and repairing, the anode 140 can recover normal power-up work.
