Abstract: The present disclosure provides a wire material cleaning device, method, and use. The present disclosure provides a wire material cleaning device, including a charged dust collecting unit, wherein the charged dust collecting unit comprises a corona wire and a tubular dust-collecting anode plate, and the corona wire is located at a center position in an axial direction of the tubular dust-collecting anode plate.

Abstract: The present disclosure provides an intermediate alloy and a preparation method therefor, and use thereof. The preparation method of the intermediate alloy includes the following steps: S1, performing stranding by taking a wire material of a doping element as a core material and taking a base material wire as a peripheral stranding wire to obtain a first stranding wire; S2, performing diffusion welding on the first stranding wire in a vacuum environment or under a protection of an inert atmosphere, so that a metallurgical bonding is formed between the wire material of the doping element and the base material wire, so as to obtain a second stranding wire; and S3, drawing the second stranding wire to obtain an intermediate alloy wire.
