Abstract
The invention relates to a method for compounding a silver-based metal and a base metal, particularly to a production method of a silver cadmium oxide copper and iron alloy. The method comprises the steps of polishing and washing, thermal compounding, diffusion annealing, secondary polishing and washing, finish rolling, slitting, punching and postprocessing. During usage of the silver cadmium oxide copper and iron alloy produced with the method, as a constituent of iron is added, direct welding can be achieved, a welding machine is not required, and the usage is more convenient.
Description
Technical field
The present invention relates to a kind of method of silver-base metal and cheap metal compound, especially a kind of Agcdo copper-iron alloy production method.
Background technology
Agcdo is the alloy that money base contains cadmium oxide, and silver and cadmium oxide can not dissolve each other.There is AgCdO5, AgCdO8, AgCdO10 and AgCdO15 etc.There is high, the anti-electrical wear of electrical conductivity and resistance fusion welding is good, contact resistance is low and stable and arc extinguishing effect.Available powders metallurgy method, internal oxidation or by the manufacture of oxidation-power metallurgic method, can obtain cadmium oxide and organize miniaturization and equally distributed alloy.In being used as, powerful contact material, for ignitron make and break contact, the air appliance contact of magnetic starter, high power relay, electric welding machine.Agcdo is also applied to the contactor of various current class; one pole, bipolar and multipole switch, moulds shell air switch; leakage switch; DC quick switch, cam switch, automobile contactor; automobile protection switch; light-operated switch, room thermostat, the various switches of microswitch and the large relay of breaking capacity and aircraft industry.He has good resistance to electrical wear, resistance fusion welding and electrical and thermal conductivity, contact resistance is little and stable, the hardness of material is better, the powder sintered extrusion process of development in recent years improves the distributional pattern of Agcdo in money base, electrical contact combination property is improved, and therefore the application of silver-base metal is very extensive.
In the market, also the product of some silver-base metals and cheap metal compound is had, modal is the compound of silver-base metal and copper base metal, but finished product is not but very desirable, this is because the product of similar this character, when welding, need to add welding compound, be still restricted when in use.
Summary of the invention
The object of invention is, provides a kind of easy to use, the Agcdo copper-iron alloy production method that can directly weld.
The technical scheme that its technical problem of invention solution adopts is: a kind of Agcdo copper-iron alloy production method, and its method is as follows:
First step polished and cleaned, puts into degreaser successively to Agcdo web, copper strips, sheet iron strip respectively and deoils, and then puts into polishing machine polishing one by one successively, cleans after polishing, cleaning post-drying;
The hot compound of second step, puts into hot combined-flow waterline by kind of the material of three after polished and cleaned and carries out hot Combined Processing, and the particular content of hot compound is in N2 gaseous environment, and carrying out rolling lower amount is roll process 50% time, and temperature conditions is 700-800 degree Celsius;
3rd step diffusion annealing, puts into diffusion annealing stove by the product after hot compound and carries out diffusion annealing, temperature 600-700 degree Celsius, and the time is 1 hour;
4th step second polishing cleaning, carries out polished and cleaned again by the product after diffusion annealing;
5th step finish rolling, by the size finish rolling of the product after second polishing according to demand;
6th step itemize, the size needed according to punching press carries out itemize to the product after finish rolling;
7th step punching press, by the product punch forming after itemize;
8th step post processing, by the product after punching press, successively through deburring, polishing, antirust treatment.
Being set to further of invention: described Agcdo web is AgCdO12 band, and degreaser is carbon tetrachloride.
Being set to further of invention: the temperature of hot compound is 760 degrees Celsius.
Being set to further of invention: diffusion annealing temperature is 640 degrees Celsius.
The above-mentioned Agcdo copper-iron alloy produced through said method, when in use, owing to adding the composition of iron, can direct welding machine, and do not need bonding machine, use convenient.
Detailed description of the invention
A kind of Agcdo copper-iron alloy of the present invention production method, its concrete production method is as follows:
First step polished and cleaned, puts into carbon tetrachloride successively deoil to AgCdO12 band, copper strips, sheet iron strip respectively, then puts into polishing machine polishing one by one successively, cleans after polishing, cleaning post-drying;
The hot compound of second step, after polished and cleaned three kind of a material is put into hot combined-flow waterline and carries out hot Combined Processing, the particular content of hot compound is in N2 gaseous environment, carrying out rolling lower amount is roll process 50% time, temperature conditions is 760 degrees Celsius, certain temperature is between 700-800 degree Celsius, but the best complex temperature of AgCdO12 band is 760 degrees Celsius;
3rd step diffusion annealing, puts into diffusion annealing stove by the product after hot compound and carries out diffusion annealing, temperature 640 degrees Celsius, and the time is 1 hour, and all, optimum annealing temperature is 640 degrees Celsius to the temperature of certain 600-700 degree Celsius;
4th step second polishing cleaning, again carries out polished and cleaned by the product after diffusion annealing, removes surperficial oil stain completely;
5th step finish rolling, by the size finish rolling of the product after second polishing according to demand, due to various equipment or service condition restricted, the size of therefore finish rolling customizes according to actual demand;
6th step itemize, the size needed according to punching press carries out itemize to the product after finish rolling;
7th step punching press, by the product punch forming after itemize;
8th step post processing, by the product after punching press, successively through deburring, polishing, antirust treatment.
Agcdo web in the present invention comprises multiple material, is to have employed AgCdO12 band in embodiment, can certainly be other Agcdo web, such as AgCdO5, AgCdO8, AgCdO10 and AgCdO15 etc.
Obviously, above-described embodiment is only used to done citing is clearly described, and the restriction not to embodiment.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still in the protection domain of invention.
