Description
Technical field
The invention belongs to process equipment and the processing technique thereof in metal fabrication techniques field, specifically silver copper oxide.
Background technology
Along with the development of science and technology, industry manufacture field is increasing to the demand of electromechanical compo, also refers to its performance simultaneously
Mark requires more and more higher.Silver copper oxide contact material is development in recent years Novel non-toxic electrical contact material quickly, has heat steady
The advantage such as reserve, resistance to arc erosion and resistance fusion welding are strong, be the ideal material at present in catalyst, relay field.
Existing silver copper oxide processing technique step is: by silver ingot, copper is placed in melting ingot casting in smelting furnace, then by gold
Belong to ingot and be processed into chip, obtain the mixing material based on silver copper oxide through High Temperature High Pressure oxidation, crush through machining,
By chip extrusion forming in punching block, the most at high temperature it is squeezed into bar, band, then obtains silver copper oxide bar, band through drawing
Material.
The existing method that ingot is made chip is usually and uses ball mill ball milling or use nebulization, ball mill
In mechanical milling process, it may be acted on by grinding compressive stress repeatedly, cause be present in intrinsic on this particle surface or newborn
The crack extesion become, and then it is directed at its broken or generation plastic deformation.When this granule is the most crushed. certain one-level of generation
New granule dyschezia is with the most levigate, this is because the crackle on new grain surface is relatively thin, and a certain minimum fracture occurs
The cause that the crackle probability of stress also reduces.When shattering process proceeds, required finished breaking stress may increase
Greatly to the degree making granule produce plastic deformation.Now, along with the generation of plastic deformation, granule just will not be by levigate.Cause
This, have a granularity ultimate value during grinding material, say, that when the grinding of material enters into the scope of superfine grinding,
The pulverization of ball mill is the most more and more difficult.An actual grinding limit is all there is in most of grinding systems, this
One limit depends on that grinding product granule produces the tendency again built up mainly, and is set up between building up and being broken
The physical equilibrium come.Long prolongation Ball-milling Time is skimble-skamble, only results in the increase of energy consumption, because meticulous granule
Cannot effectively store the elastic energy made needed for crack extesion, the powder particle that therefore ball-milling method prepares is relatively large, rear
Continuous oxidizing process is difficult to fully oxidized.Nebulization more advantage by contrast, nebulization is to be led to by melted metal liquid
Crossing high pressure to spray from shower nozzle, the method forming powder after the drop cooling of ejection, the powder of nebulization ejection is relative to ball milling
Machine ball milling powder out is less, can aoxidize more abundant, and the granule of nebulization shower nozzle ejection also has during subsequent oxidation
Size, one is due to ejection some oarse-grained drops of the uneven existence caused, and two is owing to the drop of ejection is not also coagulating
Form big liquid after contact before knot, thus have oarse-grained powder after causing the droplet formation powder that nebulization sprays
End, causes subsequent oxidation process to be difficult to fully oxidized.
