Steel wire is drawn from an initial diameter to a desired final or intermediate diameter by the use of a non-linear tapered draft. During the non-linear tapered draft, the wire is drawn through a series of successive wire, reducing the wire diameter to a desired diameter, wherein the drawing strain at each successive die is gradually reduced. The drawing strain is based upon the actual strength of the steel at each die. The wire may also be subjected to a skin pass, reducing the wire by a diameter by less than 4%, following reduction of the wire to either the final or the intermediate diameter. <IMAGE> |
