Abstract
The invention relates to a welding agent and a welding method for welding an anode steel claw. The welding method comprises the following steps of preparing the welding agent by mixing aluminum powder, magnesium powder, iron powder, titanium powder, copper oxide and silver powder with certain fineness according to a certain proportion, and then welding the anode steel claw by utilizing the welding agent; during welding, arranging a U-shaped metallic sheath between a steel-claw connecting rod and a steel-claw leg, then filling the welding agent in the gap of the U-shaped metallic sheath, igniting the welding agent, and welding the steel-claw connecting rod, the U-shaped metallic sheath and the steel-claw leg by utilizing high temperature generated by the welding agent. Compared with the prior art, only the damaged steel-claw leg needs to be excised, and then the undamaged steel-claw leg is welded onto the undamaged steel-claw connecting rod, so that a large amount of materials and working procedures are saved, and the production cost is greatly lowered; meanwhile, because the welding agent is used by the invention for respectively welding the U-shaped metallic sheath as a medium with the steel-claw leg and the steel-claw connecting rod, the welding efficiency is greatly improved.
Description
Technical field
The present invention relates to the anode steel claw that electrolytic aluminium field is used, specifically a kind of anode steel claw welding welding agent and welding method.
Background technology
In the time of electrolytic aluminium, need to capture carbon piece with anode steel claw and put into electrolytic cell as anode and carry out electrolysis, the steel pawl leg that anode steel claw captures carbon piece by steel pawl connecting rod and steel pawl connecting rod below forms.In prior art, due to the washing away and corrode of electrolyte, cause the loss of steel pawl leg, can make like this steel pawl leg not well to be connected with carbon piece, now just need to change steel pawl.Because steel pawl connecting rod does not damage, if therefore just because the damage of steel pawl leg needs integral replacing steel pawl, not only can cause the waste of steel pawl connecting rod founding materials, and will cause the raising of manufacturing cost.
Summary of the invention
Damage for solving steel pawl leg in prior art the problem that waste of material, efficiency are low, expense is high that rear integral replacing exists, the invention provides a kind of anode steel claw welding welding agent and welding method.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of anode steel claw welding welding agent, the composition of welding agent comprises the aluminium powder of 35-42%, the magnesium powder of 25-35%, cupric oxide, the iron powder of 7-14% and the titanium valve of 8-10% of 10-15%, and the silver powder of aluminium powder weight 0.1-0.3%.
In described welding agent, the fineness of aluminium powder, magnesium powder, iron powder and titanium valve is no more than 200 orders, is preferably 200-400 order.
A kind of anode steel claw welding method, comprises the following steps:
1) make the U-shaped metallic sheath matching with the steel pawl leg diameter of anode steel claw, and this metallic sheath is set on steel pawl leg, then steel pawl leg and steel pawl connecting rod are put into the shape of anode steel claw in order to welding;
2) between U-shaped metallic sheath and steel pawl leg and between U-shaped metallic sheath and steel pawl connecting rod, filling welding agent as above, the welding agent that ignites is treated welding agent all burnt, completes welding process after naturally cooling.
Beneficial effect: the present invention compared with prior art has the following advantages:
1) the steel pawl leg that only needs excision to damage, then intact steel pawl leg is welded on intact steel pawl connecting rod, a large amount of materials and operation are saved, significantly reduce production cost, simultaneously, because the present invention uses welding agent, vehicular U-shaped metallic sheath is welded with steel pawl leg and steel pawl connecting rod respectively, greatly improved welding efficiency;
2) in welding agent component of the present invention, contain a large amount of thermit reaction things, after igniting, discharge a large amount of heats, realize the effect of the U-shaped metallic sheath of Flashmelt, steel pawl leg and steel pawl connecting rod, and make three's the mutual Motion fusion of atom, greatly improved weld strength and speed of welding;
3) in welding agent of the present invention, contain titanium valve and a small amount of silver powder, improved greatly the weld seam after welding in conjunction with density and surfacing degree, cupric oxide powder is dissolved in the density that can improve the rear weld seam of welding in welding agent component, has guaranteed weld strength;
4) fineness that limits aluminium powder in welding agent, magnesium powder, iron powder and titanium valve in the present invention is no more than 200 orders, and so not only reaction speed promotes, and makes interatomic migration, merges to become and be more prone to, and completes high-intensity combination within a short period of time thereby realize.
