Abstract
The invention relates to a recognition and tracking calibration method of a non-ferrous metal material, which is characterized by comprising the following steps of: when a non-ferrous metal is completely molten, adding a certain amount of rare earth mixture into a non-ferrous metal melt, at least settling for 10 minutes after addition, and carrying out fusion-casting production after the rare earth mixture and a non-ferrous metal molten liquid are fully fused to produce the non-ferrous metal material containing a certain amount of rare earth mixture; and when a dispute on the quality of the non-ferrous metal material occurs, simultaneously placing the non-ferrous metal material to be detected and a reserved manufacturer sample on a plane-grating spectrograph for analysis, and detecting whether the rare earth content in the non-ferrous metal material to be detected conforms to the rare earth content in the reserved manufacturer sample or not through spectral line contrast and micrometer measurement to identify whether the disputed non-ferrous metal material is the product of a manufacturer or not. The invention can accurately distinguish the manufacturer of the non-ferrous metal material used by a user, thereby avoiding the occurrence of phenomena, such as false goods return, false goods exchange, and the like.
Description
Technical field
The present invention relates to a kind of identification, tracking calibration method of product, particularly relate to product identification, tracking calibration method in a kind of nonferrous materials processing, belong to the nonferrous materials manufacture field.
Background technology
The maximum characteristics of nonferrous materials processing industry are: non-ferrous metal process unit provides semifinished material for the user, also needs reprocessing to handle after the client buys.Use the user in order to guarantee ample supply and prompt delivery in case unexpected, to select the long-term supplier more than two usually.In a single day some quality problems occurring in the starting material industry will take place to return goods or the problem of exchanging goods.And nonferrous materials in process of manufacture through forging, after rolling, mechanical workout and some subsequent disposal, the various outer sign of originally being done all has been removed.The original nonferrous materials production supplier of identification will be followed the tracks of or discern like this, thereby unnecessary economic dispute can be caused.
Summary of the invention
The objective of the invention is to overcome the prior art above shortcomings, the identification method of a kind of identification or evaluation nonferrous materials is provided.The present invention is by one or more luciums of quantitative interpolation in the nonferrous metal melts material, the interpolation of these rare earth luciums has no effect to the use and the performance of nonferrous materials, and meet relevant national standard, the effect of adding these thuliums is can follow the tracks of exactly, differentiate that the employed nonferrous materials of nonferrous materials user is the material of certain factory's manufacturing of determining or the similar starting material of other producer, thereby can avoid the generation of phenomenons such as returning goods by mistake and exchange goods by mistake.
The technical solution that the present invention provides is: the identification of this nonferrous materials, tracking calibration method are characterized in:
1. melt fully when being about to come out of the stove when non-ferrous metal, the lucium that in nonferrous metal melts per ton, adds certain value, this lucium is pressed in the nonferrous metal melts with the non-ferrous metal foil wrap and with graphite rod, add with leaving standstill at least behind the lucium of non-ferrous metal foil wrap 10 minutes, after treating that lucium and molten non-ferrous metal fully merge, just the founding production after can carrying out, output contains the nonferrous materials of certain value lucium;
2. when dispute is taken place in the nonferrous materials quality, nonferrous materials to be checked and producer are reserved standard specimen to be placed on plane grating simultaneously and to take the photograph the spectrum view and go up and analyze, measure by spectral line contrast and micrometer view, whether whether detect nonferrous materials middle-weight rare earths content to be checked and conform to the content of rare earth that producer reserves in the standard specimen, be the product of this producer thereby identify controversial nonferrous materials.
Purpose to better implement the present invention, the lucium that adds certain value in the nonferrous materials of molten state is the lucium that is not more than nonferrous metal melts weight 0.008%.
Purpose to better implement the present invention, the lucium that adds in the nonferrous materials of molten state are one or more in rare-earth elements of lanthanum, cerium, praseodymium, the yttrium.
The lucium that is added is purchased from the market in the present invention, its manufacturer: the sharp rare earth of Ganzhou moral company limited, lot number: LA-3N5Ce-1N5.Certainly, the product of the same type that also can use other Rare Earth Production producers to sell.
The plane grating that is adopted is taken the photograph routine techniques and the equipment that spectrum negotiation detection method is the industry in the present invention.
Experiment showed, that the adding of these rare earth elements can improve the process industrial art performance of nonferrous materials significantly, also can not bring any detrimentally affect simultaneously the use properties of nonferrous materials.With copper is example, also will meet GB/T5231-2001 worked copper and copper combination composition and shape of product and concerned countries standard code.Rare-earth elements of lanthanum, cerium, praseodymium, yttrium add with the form of lucium, mechanical property to copper is useful, this class rare earth element can form high melting compound with impurity lead in the copper, bismuth etc., be the fine spherical grains distribution of particles in intragranular, crystal grain thinning, the high-temp plastic of raising copper, rare earth element has deoxidizing capacity preferably, can also produce stable rare earth hydride with the atomic reaction of hydrogen that fuses in the copper liquid, eliminate the harm of hydrogen.Whether when material generation quality problems or some dispute, can screen by the method for Chemical Composition analysis is the product that our company produces.
Compared with prior art, the invention has the beneficial effects as follows: by one or more luciums of quantitative interpolation in the nonferrous metal melts material, following the tracks of exactly, to differentiate that the employed nonferrous materials of nonferrous materials user is the material of certain factory's manufacturing of determining or the similar starting material of other producer, thereby can avoid mistake to return goods and the mistake generation of phenomenon such as exchange goods.
