The anti-magnetic shielding apparatus is characterized in that the apparatus comprises complete and continuous shielding anti-magnetic covers that are made of materials with high magnetic permeability and cooperate well at a welding part and a welding machine; and guiding plates that can be dismounted are arranged at the rear ends of the shielding anti-magnetic covers in a cooperation mode. According to the invention, the structure is unique; the magnetic force lines can be shielded and guided; the magnetic field can be reduced even eliminated inside the shielding space; and thus objectives of successful welding and welding quality guarantee can be achieved.
Description
Technical field
The present invention relates to the reparation of aluminium bus of electrolyzer, particularly relate to a kind of Antimagnetic shield apparatus repairing weldering electrolytic cell horizontal bus under strong magnetic field circumstance.
Background technology
In recent years, the development of national aluminum electrolysis industry is swift and violent, aluminum cell current intensity also from before 120kA develop into present 400kA and 500kA, because novel electrolytic bath power consumption is large, aluminium busbar is arranged comparatively complicated, and whole potroom produces powerful electromagnetic field.The highest field strength values that such as 400KA electrolytic cell is tested when actual motion reaches 850GS.
In Aluminum Electrolysis Production process, anode aluminium guide-bar and bus contact surface generation mechanical wear and tribo-charging spark phenomenon, there is scraggly deep trouth hole in contact surface.After repeatedly regularly replacing anode block, crimp with aluminum guide again and be energized, so that increase the connection pressure drop at this place, due to conductive area minimizing, the current density of unit are increases, cause energy consumption to increase, there are potential major safety risks, electrolytic cell is produced all the year round, produce meaningless electric energy loss by this place, cause larger economic loss.For these damages that horizontal bus occurs, the method that electrode argon arc welding (MIG) is dissolved in employing is generally needed to carry out Welding Repair.But, due to the impact of high-intensity magnetic field in cell room, during welding, equipment is difficult to normal operation at the scene, the electric current that electric welding machine exports and voltage instability, liquid state molten pool splashes, cannot stack shaping, phenomenon that this is called in the industry " arc blow ", owing to there is more weld defect, its welding quality cannot reach instructions for use at all.
In order to avoid high-intensity magnetic field affects welding quality, have a power failure, could eliminate magnetic field unless carried out series, if only separate unit electrolytic cell has a power failure because around electrolytic cell is still produced in energising, magnetic field is still very powerful.And serial electrolytic cell has a power failure, heavy economic losses will be caused.In the past 120KA, 200KA electrolytic cell horizontal bus repair welder be all pot superstructure Integral lifting is returned overhaul factory building carry out horizontal bus repair weldering and other service work, object is exactly avoid cell room internal magnetic field on the impact of service work, but 350KA, 400KA electrolytic cell flute profile is large, the superstructure transhipment at bus place needs mass transit vehicle and crane, and need the large-scale repairing factory building of construction one for this reason, certainly lead to wholesale freight, labour cost and construction factory building expense, also make bus weld repairs cycle stretch-out.
Also do not overcome the device of above-mentioned defect so far.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of structure uniqueness is provided, the magnetic line of force can be carried out shield, dredge, reduce even to eliminate magnetic field in shielding space inside, smooth welding can be reached, ensure a kind of Antimagnetic shield apparatus repairing weldering electrolytic cell horizontal bus under strong magnetic field circumstance of the object of welding quality.
The present invention realizes in the following manner:
A kind of Antimagnetic shield apparatus repairing weldering electrolytic cell horizontal bus under strong magnetic field circumstance, it is characterized in that: this device comprises complete, the continuous print shielding Antimagnetic hood of all coordinating on welding portion and welding machine of adopting magnetic conductivity good material to make, is combined with dismountable deflector in each shielding Antimagnetic hood rear end;
The hook be connected with welding position is provided with in the both sides of described shielding Antimagnetic hood;
Be double-deck at described shielding Antimagnetic hood, its material is electrical steel or high carbon steel sheet.
The present invention has following effect:
1) structure unique, the magnetic line of force is carried out shielding, dredging, reduce even to eliminate magnetic field in shielding space inside, smooth welding can be reached, ensure welding quality: Antimagnetic shield apparatus provided by the invention comprises complete, the continuous print shielding Antimagnetic hood of all coordinating on welding portion and welding machine of adopting magnetic conductivity good material to make, is combined with dismountable deflector in each shielding Antimagnetic hood rear end; The hook be connected with welding position is provided with in the both sides of described shielding Antimagnetic hood; This stout man's is according to the direction of the magnetic line of force and feature, and designing and producing a kind of device can be undertaken the magnetic line of force shielding, dredging, and reduces even to eliminate magnetic field, can reach smooth welding, ensure the object of welding quality in shielding space inside.
2) effectively improve the effect of armoured magnetic field ripple: Antimagnetic shield apparatus provided by the invention is double-deck at described shielding Antimagnetic hood, and its material is electrical steel or high carbon steel sheet, can reduce even to eliminate magnetic field in shielding space inside, ensure welding quality; Adopt magnetic conductivity good material to make radome, such as electrical steel or high carbon steel sheet, effectively can improve the effect of armoured magnetic field ripple like this.
3) three-dimensional antimagnetic shield effect is better: the key of Antimagnetic shield apparatus electromagnetic shielding provided by the invention is the conducting continuity ensureing shield, and namely whole shield must be complete, a continuous print electric conductor; Consideration need reserve welding space, and double layer screen Antimagnetic hood rear end is increased detachable deflector, for the shielding of the vertical direction magnetic line of force.
4) Antimagnetic shield apparatus provided by the invention can be applicable to welding of aluminum bus under strong magnetic field circumstance, weld strength reaches 90% of strength of parent, the conductive area of aluminium busbar and aluminum guide effectively can be improved after REPAIR WELDING completes, avoid because loose contact causes the current density of unit are to increase, the temperature of aluminium busbar is too high, energy consumption increases, and even occurs blowing out the phenomenon of striking sparks, eliminates potential major safety risks.
5) Antimagnetic shield apparatus electric welding machine antimagnetic shield cover provided by the invention, for ensureing that electric welding machine electric current, voltage export steadily.The present invention adopts said structure can carry out welding under strong magnetic field circumstance, welding fusion rate is high, welding performance close to mother metal, and process safety is reliable, simple to operate, equipment, personnel's less investment, the deadline is short, efficiency is high, is adapted at aluminium electroloysis industry and applies.
