Low-loss Zirconium Wire

The processing process of titanium or zirconium wire (less than 2 mm in diameter) is usually ingot, blanking, forging, rolling coil, grinding, annealing, drawing, pickling or polishing, and vacuum annealing. In the existing processing process, due to annealing and heating leads to the oxidation of the surface of the material, direct wear during the drawing process leads to material loss, which will lead to material waste, due to the high price of non-ferrous metals, resulting in higher product costs.

Low-loss zirconium wire processing process, which is realized according to the following process: dissolving ingot - blanking - forging - rolling coil - grinding - coating protection - annealing - drawing - pickling or polishing - vacuum annealing. A coating is applied to the surface of the zirconium metal wire before annealing to protect the zirconium wire from oxidation during the annealing process, reducing losses during the drawing process. At the same time, the coating will naturally fall off during the drawing process, there is no problem of contaminating the metal, and the cost of the paint used is very low, and the cost is almost negligible.

Specific embodiment：

The zirconium ingot is heated by a high-temperature electric furnace after opening the blank, after multiple times of forging, rolled into metal wire rods, the surface of the metal wire is trimmed (peeled) and then invaded into the latex paint for coating, air annealing at a temperature of 450-550 ° C, drawing equipment is used for drawing, the amount of deformation in the starting period of the drawing process is large, after the diameter of I mm, each deformation is maintained at 0.1 mm, and the predetermined size is pulled multiple times; the zirconium wire that reaches a predetermined size is surface treatment (pickling or polishing), Finally, vacuum annealing at a temperature of 450-550 °C can be done.
