Abstract
The invention relates to an anode carbon block group, and particularly relates to an anode carbon block group for an aluminum electrolysis cell. The anode carbon block group for the aluminum electrolysis cell comprises an aluminum guide rod and two beam steel claws, wherein the two sides of the lower part of the aluminum guide rod are welded with the inner sides of the two beam steel claws through an explosive welding block respectively. The anode carbon block group provided by the invention has the advantages that the technical problem of carbon block fracture caused by the deformation of a one-part long-beam steel claw is solved; by adopting a mode of both short beam steel claws, the beam length is reduced, the deformation of the beam steel claws is reduced, and the damage and fracture of the anode carbon block caused by the thermal expansion of the steel claw beam is eliminated.
Description
Technical field
The present invention relates to a kind of anode carbon block group, relate in particular to a kind of aluminum electrolyzing cell used anode carbon block group.
Background technology
[0002] modern Aluminium Industry, the anode carbon block group of aluminium cell is as the positive pole of electrolyzer, participate in the normal reaction of electrolyzer, anode carbon block constantly consumes in electrolytic process, after certain hour, anode scrap is changed, and after process in anode assembling workshop, the new anode carbon block of assembling, returns to potroom and recycle.
Conventionally, anode electrolytic cell charcoal piece group is made up of anode carbon block, aluminium guide bar, blast welding block, steel pawl and the phosphorus pig iron, when anode carbon block group assembling, first aluminium guide bar, blast welding block and steel pawl are welded together to composition guide rod group, by guide rod group and anode carbon block group pair, the steel pawl of guide rod group is inserted in the charcoal bowl of anode carbon block again, and the phosphorus pig iron of the melting of casting, cooling rear ferrophosphorus links together guide rod group and anode carbon block, composition anode carbon block group.
Conventionally steel pawl has casting to form by crossbeam and some conducting circular cylinder one.Along with electrolyzer capacity constantly increases, the length of anode carbon block and steel pawl crossbeam also constantly increases.In electrolyzer normal productive process, anode carbon block group is being put into temperature rise after electrolyzer, final steel pawl and charcoal deblocking temperature reach respectively 400 DEG C and 900 DEG C, because the thermal expansivity of the steel of steel pawl is than the large 4 times of left and right of the thermal expansivity of charcoal piece, therefore the beam expansion amount of steel pawl is greater than anode carbon block, causes anode carbon block carbon bowl generation deformation, and the stress producing due to deformation is greater than the permissible stress of charcoal piece, thereby cause anode carbon block to crack, even fracture.Affecting electrolyzer normally produces.
Summary of the invention
Originally the invention provides a kind of aluminum electrolyzing cell used anode carbon block group in order to solve the problems of the technologies described above, object is to reduce crossbeam length, improves the deformation of crossbeam steel pawl, eliminates the destruction being caused by steel pawl crossbeam thermal expansion antianode charcoal piece and ruptures.
For reaching the aluminum electrolyzing cell used anode carbon block group of above-mentioned purpose the present invention, comprise aluminium guide bar and crossbeam steel pawl, crossbeam steel pawl is two, weld with two crossbeam steel pawl inner sides respectively by blast welding block both sides, aluminium guide bar bottom.
Crossbeam steel pawl is symmetrical casting.
Crossbeam steel pawl material is cast steel.
Inside crossbeam steel pawl, the height of face of weld one end is 180mm ~ 200mm.
Advantageous effect of the present invention: the invention solves the technical barrier that is caused the fracture of charcoal piece by one-part form long beam deformation of steel claws, adopt the form of two hyphen joist steel pawls, reduce crossbeam length, improve the deformation of crossbeam steel pawl, eliminate the destruction being caused by steel pawl crossbeam thermal expansion antianode charcoal piece and rupture.
Brief description of the drawings
Fig. 1 is existing anode carbon block group schematic diagram.
Fig. 2 is anode carbon block group schematic diagram of the present invention.
In figure: 1, aluminium guide bar; 2, blast welding block; 3, crossbeam steel pawl; 4, the phosphorus pig iron; 5 anode carbon blocks.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.But protection scope of the present invention is not limit by embodiment.
The aluminum electrolyzing cell used anode carbon block group of the present invention as shown in the figure, comprises aluminium guide bar 1 and crossbeam steel pawl 3, and crossbeam steel pawl 3 is two, and weld with two crossbeam steel pawls, 3 inner sides respectively by blast welding block 2 aluminium guide bar 1 both sides, bottom; Crossbeam steel pawl 3 is symmetrical casting; Crossbeam steel pawl 3 materials are cast steel; The height of crossbeam steel pawl 3 face of weld one end, inner side is 180mm ~ 200mm, composition guide rod group.Guide rod group is put into the charcoal bowl of anode carbon block 5, and the phosphorus pig iron 4 of melting is poured in anode carbon block 5 charcoal bowls, and after the phosphorus pig iron is cooling, guide rod group and anode carbon block 5 form anode carbon block group.
When anode carbon block group is put into after electrolyzer, anode carbon block 5 and crossbeam steel pawl 3 expanded by heating, though the expansion of steel pawl is greater than anode carbon block, but because each crossbeam steel pawl 3 is with respect to the crossbeam steel pawl of traditional anode, not only length is only original half, and because two crossbeam steel pawls 3 are welded on the both sides of guide rod, the direction of instant heating dilatational strain also has both direction, these two factors can reduce the thermal expansion deflection of crossbeam steel pawl greatly, the fracture of avoiding charcoal piece to cause due to steel pawl beam deformation.
