LUBRICATION TREATMENT METHOD FOR METAL WIRE MATERIAL

WIPO Patent Application WO/2023/204117

A1

The present invention addresses the problem of providing a lubrication treatment method for a metal wire material that is not a combination of acid cleaning/alkaline degreasing and a phosphate/soap treatment, which has a heavy burden on the environment, but instead uses a shotblast and coating-type treatment agent to greatly decrease environmental burden, and adopts a batch scheme to have practical production efficiency, with a lubricating coating being uniformly formed on the metal wire material.　The problem is solved by this lubrication treatment method for a metal wire material, which is a method for performing a batch-type lubrication treatment on a coil-shaped metal wire material, the method including: a descale step for performing a shotblast treatment on the coil-shaped metal wire material; and a lubricating coating forming step for coating a lubricating agent on the metal wire material after the descale step, wherein, in the descale step, the coil-shaped metal wire material satisfies L/(d×N)≥1.1, where L is the coil width, d is the wire diameter of the metal wire material, and N is the number of coil windings, and the lubricating agent contains one or more coating base components (A) selected from the group consisting of an inorganic salt and an organic acid salt, and a lubricating component (B).
