Abstract
The invention provides a welding agent. The welding agent comprises, (A), 100 parts of copper oxide with the oxidation ratio of 20%-80% and the mesh of 40 to 100, (B), 10-50 parts of aluminum powder with the mesh of 100 to 200, (C), 1-10 parts of silicon dioxide, and (D), 4-22 parts of magnesium oxide or/and calcium fluoride. According to the method, exothermic reaction of the welding agent and the temperature of reduced metal liquid after reaction can be adjusted by controlling the granularity and the oxidation rate of the copper oxide, the exothermic reaction is brought into full play, the end of a welded part is fused through the high temperature of 2500 DEG C to 3400 DEG C so that fusion welding can be finished, a joint of the welded part can be of a molecular structure, and the welding quality can be ensured. An anode steel claw welding method comprises the following steps that 1), a metal sleeve is arranged on a steel claw leg in a sleeved mode, and then the steel claw leg and a steel claw connecting rod are placed into a shape of an anode steel claw to prepare for welding; 2), welding agents fill between the U-shaped metal sleeve and the steel claw leg as well as between the steel claw leg and the steel claw connecting rod, and are ignited until combustion is finished.
Description
Technical field
The present invention relates to a kind of welding agent formula and technique.
Background technology
Washing away and corroding of traditional electrolyte, causes 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, thereby causes the raising of cost.
Summary of the invention
Damage in order to solve 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 welding agent formula and technique.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of welding agent, and its of welding agent basic composition is:
A) 100 parts of oxygenation efficiency 20%-80%, 40 order-100 object cupric oxide,
B) 10 parts-50 parts of 100 order-200 object aluminium powders,
C) silica 1 part-10 part,
D) magnesia is or/and 4 parts-22 parts, calcirm-fluoride,
The present invention utilizes and controls the granularity of cupric oxide and oxygenation efficiency and adjust the molten metal temperature being reduced into after the exothermic reaction of solder flux and reaction, give full play to exothermic reaction, utilize the present invention to reach the thawing of weldment termination and complete fusion weld with the high temperature of 2500-3400 degree, making weldment joint is molecular structure, ensures welding quality.
A kind of anode steel claw welding method, comprises the following steps:
1) this metallic sheath is set on steel pawl leg, then steel pawl leg and steel pawl connecting rod is 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 described welding agent, the welding agent that ignites is treated welding agent all burnt.
Beneficial effect: the present invention compared with prior art has the following advantages:
1) only need the own steel pawl leg damaging of excision, then intact steel pawl leg is welded on intact steel pawl connecting rod, saved a large amount of materials and operation, significantly reduced production cost.
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.
