| description | PROBLEM TO BE SOLVED: To provide a manufacturing method for a steel wire with an excellent surface quality in a superb production yield. SOLUTION: The manufacturing method of the steel wire comprises surface flaw detection of the wire rod by a flaw detector installed ahead of a processing device in a processing facility for the wire rod, removal of the detected surface flaw and a process to adjust the surface roughness in the flaw-removed portion to 13.0μm or less in the centerline surface roughness Ra, and a following finish processing by the processing device. It is preferable to adjust the surface roughness Ra in the flaw-removed portion to y or less on the μm unit, wherein y satisfies the equation (1):y=22.71×ä1-(d/d0)2}2+1.797×ä1-(d/d0)2}+6.0839. When y satisfies the equation (1) turns out to be 13.0μm or more, y is assumed to be 13.0μm whatever the calculation result is, so that the maximum of y is 13.0μm. In addition, do is the diameter of the wire rod material on the mm unit, while d is the diameter of the steel wire on the mm unit after the finish processing. COPYRIGHT: (C)2004,JPO&NCIPI |
