Embodiment 1

[0030] Step 1. Press the zirconium sponge into electrode blocks with a specification of Ф50mm×300mm. Place the pressed electrode blocks in a straight line on the worktable and weld them together. The welding voltage is 10V~30V, and the welding current is 200A~400A. The welded electrode is smelted twice in an electron beam melting furnace to prepare a zirconium ingot, then the zirconium ingot is stripped and polished, and then heated to 900°C in a resistance furnace for 2 hours, and then placed on the forging equipment after being discharged. Forging into a Ф40mm bar blank; the vacuum degree before melting of the electron beam melting is ≤8.0×10 -3 Pa, air leakage rate ≤0.15Pa / min (leakage measurement 3min), melting current 3kA~4kA, melting voltage 20V~40V;

[0031] Step 2. Heat the bar stock described in step 1 to 650°C and keep it for 1 hour, and then roll the heat-preserved bar stock into a bar of Ф8.0mm. During the rolling process, control the feed rate of the bar to 2m / min, ...

[0048] Step 1. Press the zirconium sponge into electrode blocks with a specification of Ф50mm×300mm. Place the pressed electrode blocks in a straight line on the worktable and weld them together. The welding voltage is 10V~30V, and the welding current is 200A~400A. The welded electrode is smelted in an electron beam melting furnace for 3 times to prepare a zirconium ingot, then the zirconium ingot is stripped and polished, and then heated to 900°C in a resistance furnace for 2 hours, and then placed on the forging equipment after being discharged. Forging into a Ф40mm bar blank; the vacuum degree before melting of the electron beam melting is ≤8.0×10 -3 Pa, air leakage rate ≤0.15Pa / min (leakage measurement 3min), melting current 3kA~4kA, melting voltage 20V~40V;

Abstract

The invention discloses a method for preparing zirconium metal filaments. The method comprises the steps of firstly, preparing zirconium ingots and forging bar billets; secondly, rolling the bar billets into bars and machining and removing surface scales; thirdly, drawing the bars to obtain wires; fourthly, performing acid cleaning to the wires and then carrying out vacuum annealing; fifthly, carrying out multi-path drawing on the wires after vacuum annealing, and then performing vacuum annealing to the drawn wires; sixthly, carrying out acid pickling, prefilming, electroplating and flushing on the wires subjected to vacuum annealing sequentiall, and then drying; seventhly; seventhly, bundling the dried wires and loading into copper tubes and compounding on a broaching machine so as to obtain composite tubes, and drawing after vacuum annealing; and eighthly, carrying out acid pickling on the drawn composite tubes to remove copper and oxidation films, flushing with deionized water, and naturally drying to obtain the zirconium fiber filaments. According to the method, the bundling and drawing process is adopted to prepare the zirconium fiber filaments, and the zirconium composite tube cannot be fractured during the bundling and drawing process due to selection of proper zirconium-copper cross section ratio.

Description

Technical field [0001] The invention belongs to the technical field of metal processing, and specifically relates to a method for preparing zirconium metal fiber filaments. Background technique [0002] Zirconium fiber filaments have been commercialized abroad, and are widely used in aircraft ejection and escape systems, underwater photographic equipment, etc. However, there are no reports on the diameter and production process of zirconium fiber filaments. The existing related metal fiber wires are all stainless steel and other metal wires, and there is no patent for zirconium fiber wires. An invention patent named "a metal fiber thread and its preparation process" with the authorization number ZL200610086041.2, although the monofilament can be drawn to 6μm, its disclosed composition is mainly iron. And its smelting process, annealing process, monofilament drawing process, electroplating process, cluster drawing process and cleaning treatment process are all different from the...
