METHOD OF DESCALING METAL WIRE ROD AND APPARATUS THEREFOR

摘要

An apparatus for removing scales from metal wires including: a liquid container tank 12 through which the metal wires 10 pass, mixing nozzles 14 disposed to allow the metal wirings to pass through the liquid container tank for injecting a high-pressure liquid toward the metal wires 10; a high-pressure pump 16 for feeding the high-pressure liquid to the mixing nozzles 14; and cyclone separators 20 which are slurry feeders for feeding a slurry of the liquid with which an abrasive scavenging agent is mixed to the mixing nozzles 14. The mixing nozzles 14 inject the slurry of the abrasive scavenging agent together with the high-pressure liquid so that the abrasive scavenging agent bombards the scales on the surfaces of the metal wires 10 to remove the scales. Provision is further made for the cyclone separators 20 to recover the liquid with which the abrasive scavenging agent is mixed, and separate the liquid and the abrasive scavenging agent from each other, and a wheel-type filter 40 for further separating the abrasive scavenging agent. The cyclone separators 20 feed the abrasive scavenging agent in slurry form to the mixing nozzles 14, and separate the liquid components.
