s21, soaking the finished product of the first iron-chromium-aluminum alloy material, and then flushing to obtain a second iron-chromium-aluminum golden wire; wherein, the liquid for soaking and flushing is water;
s31, performing heat treatment on the second iron-chromium-aluminum alloy material to obtain an iron-chromium-aluminum golden thread finished product. For specific process parameters and properties, see table 1.
Table 1 preparation process parameters and properties of iron-chromium-aluminum-gold wire finished product
Comparative example 2
Drawing by using a wire drawing powder by adopting a straight wire drawing machine, wherein the drawing process is as shown in figure 5, the surface of a hot rolled wire rod after heat treatment is coated with an anhydrous sodium sulfate coating, the hot rolled wire rod is fully dried at 180 ℃ and then drawn by using lubricating powder, naOH and nitric acid are respectively used for soaking and cleaning after drawing, and finally a golden annealing heat treatment is carried out at 800 ℃ by using a continuous heat treatment furnace to obtainThe surface roughness of the finished iron-chromium-aluminum-gold wire is 1.928 mu m.
The finished product of the iron-chromium-aluminum golden silk with golden surface can be successfully prepared by the embodiment of the application, thereby meeting the requirements of partial users on the appearance of the product, and the application can be seen in figure 3. The comparative example 1 has less drawing pass and higher roughness, the comparative example 2 does not adopt the scheme of the embodiment of the application, and the prepared iron-chromium-aluminum golden silk finished product has darker color, and can be seen in fig. 4.
The foregoing is only a specific embodiment of the application to enable those skilled in the art to understand or practice the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
