Abstract
The invention discloses a method for preventing molten iron from flowing outwards in deep and narrow seam welding, which adopts a U-shaped base plate, spot-welds the U-shaped base plate on the end surface of a steel bar, uses an alignment device to place the steel bar with the U-shaped base plate at a position corresponding to the root of a steel claw of an anode guide rod, supports the U-shaped base plate and the root of the steel claw of the anode guide rod together, reduces gaps between the roots of the steel claw of the anode guide rod, and then leads a deep and narrow seam welding gun to penetrate into the U-shaped base plate for arc welding. According to the method for preventing the molten iron from flowing outwards in the deep and narrow seam welding, the U-shaped base plate is arranged at the narrow seam to be welded, so that the molten iron can be prevented from flowing outwards from two sides, and the problem that the molten iron flows outwards in the deep and narrow seam welding is solved.
Description
Technical Field
The invention belongs to the field of deep and narrow seam welding, the field of aluminum electrolysis anode production and the field of aluminum electrolysis anode steel claw repair production lines, and particularly relates to a method for preventing molten iron from flowing outwards in the deep and narrow seam welding.
Background
The anode guide rod assembly is used as a main structure of electrolytic aluminum, is a key link of a current path, and has the characteristics of large quantity and easiness in damage. For a long time, after the cast anode steel claw is used for a short time, the cast anode steel claw needs to be manually welded and repaired and then used again. Due to the limitation of a welding process and the uncertainty of manual operation, the anode steel claw is high in pressure drop, easy to fall off or crack and short in service life in the using process, the operation cost of an enterprise is greatly increased, and the number of operators is increased.
In the prior art, the invention patent with publication number CN103846564A discloses a method for repairing a steel claw of an anode guide rod, which comprises the following steps: firstly, polishing a welding surface of a steel claw on a cross beam by using abrasive cloth to be smooth; secondly, polishing the welding surface on the steel claw by using abrasive cloth to be smooth; thirdly, chamfering the circumference of the welding surface of the steel claw; and finally, carrying out full welding. In addition, the invention patent with the publication number of CN106735661A discloses a method for welding an anode guide rod and a steel claw of an electrolytic tank in a hot melting way, which comprises the following steps: welding a reinforcing structure mould to the steel claw, additionally welding a steel plate outside the reinforcing structure mould to form a cavity between the steel plate and the mould, and filling asbestos wool bonded by water glass into the cavity; preheating the surface to be welded of the steel claw to above 700 ℃, and then quickly taking down and mounting the steel claw on a welding frame; placing the anode guide rod into a reinforcing structure die, and then fixing the anode guide rod and the steel claw; pasting a layer of mud on the outer edge of the reinforced structure mould in contact with the anode guide rod; then heating the welding surface of the steel claw to over 1100 ℃; putting the welding flux into a crucible barrel, inserting matches, fixing the crucible on a welding frame and locating above the pouring gate; igniting match to make the welding flux react, after pouring, naturally cooling the welding seam, and removing slag.
In recent years, in order to improve the repair quality of the aluminum electrolysis anode steel claw, the technicians in the field propose to weld the claw head (steel bar) of the anode guide rod steel claw by adopting a deep and narrow seam welding process, but the problem that molten iron flows outwards during the deep and narrow seam welding is solved urgently.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a method for preventing molten iron from flowing outwards in a deep and narrow seam welding process.
The invention is realized by the following steps: the method comprises the steps of adopting a U-shaped base plate, spot-welding the U-shaped base plate on the end face of a steel bar, using an alignment device, placing the steel bar with the U-shaped base plate at a position corresponding to the root of a steel claw of an anode guide rod, abutting the U-shaped base plate and the root of the steel claw of the anode guide rod together, reducing a gap between the roots of the steel claw of the anode guide rod, and then, deeply and narrowly welding a welding gun into the U-shaped base plate for arc welding.
Compared with the prior art, the method for preventing the molten iron from flowing outwards in the deep and narrow seam welding can prevent the molten iron from flowing outwards to two sides by adopting the U-shaped base plate and placing the U-shaped base plate at the narrow seam to be welded, thereby solving the problem of the molten iron flowing outwards in the deep and narrow seam welding.
Drawings
FIG. 1 is a drawing of a deep and narrow seam welding structure of an anode guide rod steel claw.
FIG. 2 is a schematic diagram of the arrangement of the U-shaped backing plate for the deep and narrow seam welding of the steel claw of the anode rod.
The labels in the figures are: 1-deep narrow seam welding gun, 2-steel bar, 3-U-shaped backing plate, 4-anode guide rod steel claw root and 5-anode guide rod.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in figure 1, the welding device mainly comprises a U-shaped backing plate 3, when in use, the U-shaped backing plate 3 is spot-welded on the end surface of a steel bar 2, an alignment device is used, the steel bar 2 with the U-shaped backing plate 3 is placed at the corresponding position of the root part 4 of an anode guide rod steel claw, the U-shaped backing plate 3 and the root part 4 of the anode guide rod steel claw are abutted together, the gap between the root parts 4 of the anode guide rod steel claw is reduced as much as possible, and then a deep and narrow gap welding gun 1 is deeply inserted into the U-shaped backing plate 3 for arc starting welding.
The invention is not only suitable for the welding of the steel plate of the anode guide rod, but also suitable for other conditions of deep and narrow seam welding, and the size and the shape of the U-shaped backing plate 3 only need to be adjusted along with the size and the shape of an actual weldment.
