Abstract:
1. A method of removing scales formed on the surfaces of metal wires during a process of stretching the wires, comprising: injecting a slurry in which an abrasive scavenging agent is mixed with a liquid, together with a high-pressure fluid, toward the surfaces of the metal wires from mixing nozzles that inject the high-pressure liquid, and bombarding the abrasive scavenging agent in the liquid that is high-pressure injected on the scales on the surfaces of the metal wires to remove the scales, wherein spherical fine particles selected from the group consisting of spherical zircon beads, spherical zirconia beads and spherical stainless steel beads having particle sizes of from about 40 μm to about 800 μm are used as the abrasive scavenging agent and the liquid with which the abrasive scavenging agent is mixed is a liquid obtained by mixing a water-soluble cutting oil with water, and the high-pressure water containing the abrasive scavenging agent in the liquid is injected toward the surfaces of the metal wires.
