Compared with the prior art, the welding device has the advantages that the welding efficiency is higher, the quality of welding is better, and electric consumption of the welding is lowered significantly; the service life of the electrolytic tank is prolonged for at least more than a year, the welding device is prominent in social effect and is applicable to strong magnetic working environment.
Description
Technical field
The utility model relates to a kind of welding equipment that adapts to operation in large magnetic field environment, is not subject to the electric tank cathode assembly of magnetic interference, belongs to electrolytic aluminium field.
Background technology
Electrolytic cell is mainly by cell body, cathode assembly and refractory material form, cathode assembly is a kind of large expendable part, once furnace bottom pressure drop, reach about 600mv or other reasons and must stop groove renovation, change cathode assembly, long-term Aluminum Electrolysis Production facts have proved, there is direct relation with connecting of cathode assembly age in the groove of electrolytic cell, directly have influence on groove age and ton aluminium power consumption, no matter current electrolysis aluminium manufacturing enterprise is newly-built electrolytic cell or the renovation of old groove, the connecting mode of cathode steel bar and negative busbar rod iron all adopts the method for artificial buttress weldering, there is following defect in the method, for Aluminum Electrolysis Production has been buried hidden danger.1, linking intensity is low, weld strength is low, effective area is little, causes linking intensity fragile, and effective area is about 60% of rod iron cross section; 2, electrical efficiency is low, and heating oxidation is serious, shortens the service life of electrolytic cell; 3, operating efficiency is low, and labour intensity is high, and the cycle is long; 4, power consumption is high, increases Aluminum Electrolysis Production cost; 5, the unstability of artificial buttress weldering brings risk also to the safety in utilization of electrolytic cell.
Summary of the invention
The purpose of this utility model is to overcome problems of the prior art, provide a kind of in strong magnetic field circumstance electrolytic cell cathode steel bar integral seamless welding equipment.
For achieving the above object, the utility model adopts following technical scheme: magnetic-field disturbs cathode steel bar integral seamless welding equipment, comprise cathode steel bar and bus rod iron, cathode steel bar and bus rod iron are arranged on parallels by dry type mould, and cathode steel bar, bus rod iron, dry type mould and parallels form welding space; In described welding space, be contained with scaling powder, positive and negative electrode is inserted in scaling powder.
Described dry type mould 4 is exotic material mould.
Operation principle: cathode steel bar forms the welding space of a relative sealing under the clamping of dry type mould with parallels with bus rod iron, thereby scaling powder is injected to welding space and form scaling powder pond, two positive and negative electrodes are inserted in scaling powder pond, form the electrode loop of positive electrode → scaling powder pond → negative electrode, the surface that cathode steel bar contacts with scaling powder with bus rod iron under the effect of high temperature scaling powder can be heated and melt about 10mm fast, mix mutually with the molten steel of electrode melting, thereby solidify, form a seamless integral body under dry type mould quick cooling.
Experimental results show that: by the electrolysis medium aluminium enterprise measuring and calculating of 400,000 tons/year of scales, can save every year the electrolytic cell expense of rebuilding or renovate and be about 5,000,000 yuan, the electricity charge can be saved 1,500 ten thousand degree, and economic benefit is very remarkable.
Compared with prior art, tool has the following advantages the utility model:
1, because this technique welding efficiency is high, quality is good, and integrated cost is about existing artificial buttress weldering and rebuilds or renovate 80% of electrolytic cell, and single groove operating efficiency is artificial 4 times.
2, power consumption significantly declines, and furnace bottom pressure drop is low, approximately can fall 50 ~ 100mv.
3,, Cao Age extends, and at least on existing basis, extends more than 1 year.
4, improved electrolytic cell operational reliability, energy conservation and consumption reduction effects is very huge, and social benefit is obvious.
5, because this equipment forms independently current supply circuit, again without arc light, be not subject to magnetic interference, adapt to strong magnetic field circumstance operation.

Fig. 3 is the utility model structure top view.
Fig. 4 is the utility model welding effect figure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, artificial buttress weldering product effect: be connected effective area between cathode steel bar and bus rod iron little, estimate that the effective area of connection place is about 60% of rod iron cross section.
As shown in Figure 2,3, magnetic-field disturbs cathode steel bar integral seamless welding equipment, comprise cathode steel bar 1 and bus rod iron 2, cathode steel bar 1 and bus rod iron 2 are arranged on parallels 3 by dry type mould 4, and cathode steel bar 1, bus rod iron 2, dry type mould 4 and parallels 3 form welding space 5; In described welding space 5, be contained with scaling powder, positive and negative electrode 6 is inserted in scaling powder.
Concrete structure: cathode steel bar forms the welding space of a relative sealing under the clamping of dry type mould with parallels with bus rod iron, thereby scaling powder is injected to welding space and form scaling powder pond, two positive and negative electrodes insert in scaling powder pond, form the electrode loop of positive electrode → scaling powder pond → negative electrode, the surface that cathode steel bar contacts with scaling powder with bus rod iron under the effect of high temperature scaling powder can be heated and melt about 10mm fast, mix mutually with the molten steel of electrode melting, thereby solidify, form a seamless integral body under dry type mould quick cooling.
As shown in Figure 4, the connection effective area between cathode steel bar and bus rod iron has reached 100% substantially.
The utility model is simple in structure, and the present embodiment is only a specific embodiment of the present utility model, does not for example form, to restriction of the present utility model: the dry type mould in the utility model also can adopt water cooling mold.Structure of the present utility model can also be applicable to other association areas.
