Description
Technical field
The invention belongs to metal fabrication techniques fields, the specifically process equipment and its processing technology of silver copper oxide.
Background technology
With the development of science and technology, demand of the industry manufacture field to electromechanical compo is increasing, while also its performance is referred to
Mark requires higher and higher.Silver copper oxide contact material is the novel non-toxic electrical contact material that have developed rapidly in recent years, has heat steady
It sets, the advantages that resistance to arc erosion and resistance fusion welding are strong, is the ideal material at present in contactor, relay field.
Existing silver copper oxide processing technology step is：By silver ingot, copper is placed in melting and ingot casting in smelting furnace, then will be golden
Belong to ingot and be processed into clast, aoxidizes to obtain the mixing material based on silver copper oxide through high temperature and pressure, it is broken through over mechanical processing,
Clast is press-formed in punching block, is then squeezed into item, band at high temperature, silver copper oxide item, band are obtained using drawing
Material.
The existing method that clast is made in ingot is usually used ball mill ball milling or uses spray-on process, ball mill
It may repeatedly be acted on by grinding compression in mechanical milling process, be caused to be present on the particle surface intrinsic or newborn
At crack extesion, and then it is broken or generate plastic deformation to be directed at its.Certain level-one that is generated when the particle is constantly crushed
Newly particle is just difficult to further levigate, this is because the crackle on new grain surface is thinner, and a certain minimum fracture occurs
The cause that the crackle probability of stress also reduces.When shattering process continues, required finished breaking stress may increase
Greatly to the degree for making particle generate plastic deformation.At this point, with the generation of plastic deformation, particle just will not be most by levigate.Cause
This, can be there are one granularity limiting value when grinding material, that is to say, that when the grinding of material enters the range of ultra-fine grinding,
The pulverization of ball mill is just more and more difficult.All there is an actual grinding limit in most of grinding systems, this
One limit depends on grinding product particle and generates the tendency built up again mainly, and builds up and set up between broken
The physical equilibrium come.Long extension Ball-milling Time is skimble-skamble, only results in the increase of energy consumption, because of meticulous particle
The elastic energy made needed for crack extesion can not be effectively stored, therefore powder particle made from ball-milling method is relatively large, rear
It is difficult in continuous oxidation process fully oxidized.Spray-on process has more advantage in contrast, and spray-on process is to lead to molten metal liquid
It crosses high pressure to spray from nozzle, the method for forming powder after the drop cooling of ejection, the powder that spray-on process sprays is relative to ball milling
The powder smaller that machine ball milling comes out can aoxidize more fully during subsequent oxidation, and the particle that spray-on process nozzle sprays also has
Size, when due to spray it is uneven caused by there are the drops of some bulky grains, second is that the drop due to ejection is not coagulating also
Big liquid is formed after contact before knot, the powder of bulky grain is had after the droplet formation powder sprayed so as to cause spray-on process
End causes subsequent oxidation process to be difficult to fully oxidized.
