Description
Technical field
The utility model relates to a kind of structure of anode steel construction energy-conserving anode steel pawl, belongs to aluminum electrolysis industry anode steel jaw technical field.
Background technology
Anode steel jaw is the device that aluminium electrolysis enterprise must use in daily production, current anode steel jaw is integral cast steel part, conventional anode steel jaw has three kinds, one is singlely under steel pawl crossbeam to be arranged with four steel pawl heads, another kind is that double-row is shown six steel pawl heads under steel pawl crossbeam, also has eight steel pawl heads of double arrangement under steel pawl crossbeam.
In Aluminum Electrolysis Production, the scaling loss of steel pawl head is a kind of ubiquitous problem, and the scaling loss of arbitrary steel pawl head of anode steel jaw all can make steel pawl reuse, so the maintenance of steel pawl also becomes one of routine work of Aluminum Electrolysis Production.In the time that steel pawl head damage quantity exceedes 50%, steel pawl just need to be scrapped.The maintenance of steel pawl and scrap the production cost that has increased beyond doubt electrolytic aluminum.
Traditional steel pawl restorative procedure is weld all around method; weld all around method is with gas welding, the steel pawl head part of scaling loss to be sliced off; raw steel pawl head cut surface is docked with steel pawl feed supplement part (one section of cylindrical steel rods); then the interface weld all around one after docking along both with carbon dioxide-shielded welding is enclosed, and the two is welded together.There is following problem in this kind of extensive method for maintaining: 1, steel pawl head scaling loss part is uneven with rear cut surface under gas welding, steel pawl feed supplement part is not close contact with contacting of steel pawl head cut surface, but although steel pawl feed supplement part end face is smooth contact with steel pawl head cut surface after, there is very large gap in contact surface.After weld all around, just periphery one circle can reach conductive effect, and the inside is because the uneven contact in two sides is bad, conductive area greatly reduces, electroconductibility extreme difference, so can cause the anode steel jaw after maintenance to increase much with new anode steel jaw phase specific pressure drop, power consumption also increases thereupon; 2, weld all around welding is just enclosed the steel pawl head after cutting and the periphery weld all around one of steel pawl feed supplement part contact site, and weldering meat is less, insufficient strength, and in Aluminum Electrolysis Production, steel pawl feed supplement part is easy to come off, and falls in the electrolyzer of work, causes industrial accident; 3, generally, aluminium manufacturer is adopting weld all around method to keep in repair after the half pawl head of same steel pawl, this steel pawl will be scrapped, this is mainly because the pressure drop that adopts this kind of method to increase is a lot, if after all pawl head is all repaired by this method, the cost of adjusting its power consumption will be far longer than the cost that more renews steel pawl, can only be also the of short duration prolongation steel pawl life-span so adopt weld all around method, does not reach the object of basic solution steel pawl burning problems.
Summary of the invention
The purpose of this utility model is textural defect and the method for maintaining defect for steel pawl Quality Down after the pressure drop increase of existence after easy scaling loss and reparation in existing steel pawl use, poorly conductive, reparation, provide a kind of steel construction energy-conservation steel pawl, the utility model corrosion-and high-temp-resistant is strong, can greatly reduce steel pawl head scaling loss in process of production, pressure drop low electric conductivity is good, and in electrolyzer, be difficult for being corroded, impurity can not brought in aluminium liquid, reduce the ferro element of aluminium ingot, thereby improve aluminium grade.
The purpose of this utility model is achieved in the following ways:
The utility model comprises steel combined with aluminum piece, steel pawl core, steel pawl core housing, it is characterized in that: steel pawl core is the claw type steel construction piece forming by pawl head matrix with the pawl head that pawl head matrix is connected as a single entity, be provided with union lever in pawl head matrix center of top, steel pawl core housing is a housing identical with steel pawl core shape, steel pawl core housing is by base case section, the pawl head sleeve sections being connected with base case section, and the end cap that is encapsulated in pawl head sleeve sections port part forms, steel pawl core is contained in steel pawl core housing, the end cap welding of the pawl cephalic par of steel pawl core and steel pawl core housing, union lever stretches out from the base case section top of steel pawl core housing, between the sidewall of steel pawl core and steel pawl core housing, leave space, the centre of steel combined with aluminum piece is provided with connecting hole, the union lever of steel pawl core inserts in connecting hole and is connected with steel combined with aluminum piece, and steel combined with aluminum piece and steel pawl core housing are connected.
The pawl head number of described steel pawl core is four or more.
The pawl head number of described steel pawl core is four, six or eight.
The utility model has the advantages that: the pawl head sleeve sections stable material quality scaling loss of steel pawl core housing is few, steel pawl core is the skeleton construction that strengthens electroconductibility, increase steel pawl electroconductibility, pressure drop is little, the pawl head sleeve sections material erosion resistance of steel pawl core housing is strong, aluminium ingot grade and material heat-and corrosion-resistant are increased, extend the work-ing life of steel pawl, reduced the maintenance of steel pawl and dropped into; According to this structure, the anode steel jaw of scaling loss in using is repaired, the use durability degree of the anode steel jaw after reparation is identical with new anode steel jaw with electroconductibility performance, greatly reduces the production cost of electrolytic aluminum.
