Abstract
The utility model relates to the field of aluminum electrolysis, in particular to a protective wall for the repair of damaged side furnace wall of an aluminum electrolysis cell without the shutdown of the aluminum electrolysis cell. The protective wall comprises an aluminum electrolysis cell side steel plate, an aluminum electrolysis cell silicon carbonitride brick, a protective wall, an anode, furnace burden and the electrolysis cell, wherein the protective wall is arranged on the inner side of the aluminum electrolysis cell silicon carbonitride brick which is on the outer side of the anode in the aluminum electrolysis cell. The utility model has the benefit that through the technical scheme that the damaged side furnace wall is repaired without the shutdown of the aluminum electrolysis cell, electrolyte and aluminum melt are effectively prevented from seepage, so as to eliminate the possible leakage of the cell during the repair of the furnace wall. The protective wall provided by the utility model has a simple structure, is easy to operate, can save a large amount of cost, and can be used for the repair of the damaged side furnace wall of the electrolysis cell in the aluminum electrolysis industry.
Description
Technical field
The utility model relates to field of aluminum electrolysis, specifically relates to a kind of aluminum cell side stove and helps breakage not stop groove reparation protective wall.
Background technology
In the accumulation of the used electrolyzer of electrolysis of aluminum industry production aluminium ingot along with the production time, the phenomenon of arch, protuberance caused certain influence to normal production operation in part electrolyzer sideways furnace wall occurred.Electrolyzer because occur that sidepiece is rubescent, silicon carbide brick is shifted, come off, phenomenon such as protuberance, cause electrolytic cell currents bias current, low, the replacing anode difficulty of electrolytic efficiency, above phenomenon occurs at electrolyzer, usually remedial measure is to stop the groove reparation, but it is bigger to stop the loss that groove repairs.
The analysis of causes of sideways furnace wall protuberance:
(1) design defect.Originally carbonitride of silicium commentaries on classics is that combined type designs up and down, and the easy infiltration of this design ionogen is the seam crossing of carbonitride of silicium commentaries on classics up and down, causes the sideways furnace wall protuberance.
(2) the brickwork poor quality causes early damage.
(3) roasting and starting and the final-period management of new fluting are bad, cause the distortion of electrolyzer burner hearth.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency that exists at prior art, provides a kind of aluminum cell side stove to help breakage not stop groove reparation protective wall.
The breakage of a kind of aluminum cell side stove of the utility model group does not stop the groove reparation and is achieved by following technical proposals with protective wall: the breakage of a kind of aluminum cell side stove of the utility model group does not stop groove reparation protective wall, comprise electrolyzer sidepiece steel plate, electrolyzer carbonitride of silicium brick, protective wall, anode, furnace charge, electrolyzer, described protective wall is arranged on the inboard of the outside electrolyzer carbonitride of silicium brick of aluminium cell inner anode.
The breakage of a kind of aluminum cell side stove of the utility model group does not stop the groove reparation has following beneficial effect compared with prior art with protective wall: occur at aluminium cell that sidepiece is rubescent, silicon carbide brick is shifted, come off, phenomenon such as protuberance, cause electrolytic cell currents bias current, electrolytic efficiency low, when changing anode difficulty phenomenon, adopt the utility model not stop groove recovery technique scheme, prevented that effectively ionogen and aluminium liquid from oozing out, stopped contingent bakie accident in the repairing stove nation process.The utility model has the advantages that: a, calculate, can produce 20 tons of primary aluminum as not stopping groove with the fastest light maintenance speed 12 days;
B, as stopping the groove light maintenance, the restarting expense can reach 540960 yuan (seeing following table for details)
| Title | Unit | The amount of money (unit) | Title | Unit | The amount of money (unit) |
| Burnt grain | 1 ton | 4000 | Soda ash | 1 ton | 1600 |
| Graphite Powder 99 | 0.5 ton | 2600 | Electrolyte block | 3.6 | 28800 |
| Anode block | 31.68 ton | 142560 | Electric energy | 400,000 degree | 130000 |
| Sodium aluminum fluoride | 32 tons | 230400 | Calcium | 0.5 ton | 1000 |
Voltage ratio is more steady in C, the whole electrolysis tank furnace nation mending course, and voltage is along with the fluctuation of electric current is fluctuateed between 4.125～4.20v, repairs forward and backward magnitude of voltage and coexists within the zone of reasonableness, and primary aluminum quality held stationary does not change.
The breakage of a kind of aluminum cell side stove of the utility model group does not stop that the groove reparation is simple with Guardwall structures, and processing ease can be saved great amount of cost, and the utility model can be applicable to the reparation of electrolysis of aluminum industry electrolyzer sideways furnace wall breakage.
