Description
Technical field
The utility model is related to technical field of electrolytic aluminum production more particularly to a kind of anode steel claw double teeming reparation to disappear
Mould.
Background technology
Anode steel claw is subjected to the erosion of high-temperature electrolyte in aluminium electrolysis process, and carries large capacity electric current, leads to steel pawl
Seriously corroded.It works after a period of time, the steel pawl of jointed anode carbon block will be tapered, and attenuate position resistance of steel pawl is caused to increase
Greatly, serious, energy consumption of generating heat increases, to further speed up corrosion process.At present to the reparation of anode steel claw mainly using welding
Mode, row welds new steel pawl again after the steel claw portion of corrosion is cut, but generally existing service life is short, repairing quality is unstable
The problems such as.After further investigation, inventor carries out remelting using factory's internal intermediate frequency stove smelting system to the steel pawl under cutting, adopts
Anode steel claw is repaired with the mode of compound double teeming, it is compound in the access of steel nail-press cut node by vacuum pressing and casting using evaporative pattern
Combination is cast, then completes the final reparation of anode steel claw by composite casting.
Utility model content
The utility model provides a kind of anode steel claw double teeming reparation evaporative pattern, insufficient to solve the above-mentioned prior art.It is logical
It crosses the tubular structure that external mold is formed after vacuum casting above anode steel claw end to be repaired and limits the compound of anode steel claw reparation
Casting area, several club shaped structures that cooperation internal model is formed above anode steel claw end to be repaired are to increase the engagement of composite casting
Site advantageously ensures that anode steel claw double teeming repairing quality, prolongs the service life to improve the firmness of composite casting.
In order to realize the purpose of this utility model, intend using following technology：
Anode steel claw double teeming reparation evaporative pattern, which is characterized in that including external mold and several internal models, external mold is tubular, bottom
Portion, which is arranged, to be fixed at anode steel claw cut end, and internal model is that rodlike, lower end is inserted in the hole slot opened up at anode steel claw cut end
In, upper end is set in external mold.
Further, external mold bottom is equipped with flaring structure with anode steel claw cut end joint.
Further, external mold Basolateral wall is equipped with stiffening ring.
Further, top and bottom junction is equipped with throat structure.
Further, internal model is 1 ~ 3.
Further, after the fixation of anode steel claw cut end, external mold and internal model overhead height are equal for external mold and internal model.
The utility model has the beneficial effects that：
1, the tubular structure that the utility model is formed after vacuum casting above anode steel claw end to be repaired by external mold
Limit the composite casting region of anode steel claw reparation, several rodlike knots that cooperation internal model is formed above anode steel claw end to be repaired
Structure is to increase the bond site of composite casting, to improve the firmness of composite casting, advantageously ensures that anode steel claw double teeming is repaiied
Compound body amount prolongs the service life.
2, the flaring structure that the utility model is arranged by external mold bottom is to improve the company of external mold and anode steel claw cut end
Connect firmness, meanwhile, by Basolateral wall be equipped with stiffening ring, with reinforce at flaring mechanism with the connection of anode steel claw cut end
Intensity ensures the mechanical strength of the anode steel claw after repairing.
3, the throat structure that the utility model is arranged by internal model top and bottom junction, to improve internal model and anode steel
The firmness of the connection of nail-press cut node hole slot.
Description of the drawings

Fig. 3 shows the utility model application schematic diagram in embodiment.
Specific implementation mode
As depicted in figs. 1 and 2, anode steel claw double teeming reparation evaporative pattern, including external mold 1 and several internal models 2.External mold 1 is
Tubular, bottom, which are arranged, to be fixed at anode steel claw cut end 9, after vacuum casting, external mold 1 disappear and in anode steel claw cut end 9
Top forms steel pawl shell, limits composite casting region.Internal model 2 is inserted at anode steel claw cut end 9 for rodlike, lower end 22 and opens
If hole slot 91 in, upper end 21 be set in external mold 1, after vacuum casting, internal model 2 disappear and above anode steel claw cut end 9
Several independent club shaped structures are formed, to increase compound interface area in composite casting, to reinforce answering for composite casting layer
Fastness is closed, ensures anode steel claw repairing quality.
1 bottom of external mold is equipped with flaring structure 11 with 9 joint of anode steel claw cut end.To improve external mold 1 and anode steel
The firmness of the connection of nail-press cut node 9.
1 Basolateral wall of external mold is equipped with stiffening ring 12.So as to reinforce at flaring mechanism 11 with the company of anode steel claw cut end 9
Intensity is connect, ensures the mechanical strength of the anode steel claw after repairing.
Upper end 21 and 22 junction of lower end are equipped with throat structure 23.To improve the firmness of the connection of internal model 2 and hole slot 91.
Internal model 2 is 1 ~ 3.The rodlike metal structure that the casting of internal model 2 is formed is compound for increasing during composite casting
The bond site of cast layer.
After the fixation of anode steel claw cut end 9, external mold 1 is equal with 2 overhead height of internal model for external mold 1 and internal model 2.External mold 1 expands
