Assignee:

American Precision Steel Company L.P.

International Classification:

B32B015/02

US Classification:

Abstract:

A continuous in-drawing line process and system for drawing stainless steel wire is provided wherein wire is (1) brushed in an inlet brush station to remove oxide film from the wire surface; (2) coated with a lubricant carrier coating which is dried then subsequently cooled; (3) drawn through a drawing machine using a lubricant; and (4) brushed to remove residual carrier compounds from the surface of the drawn wire. The system for carrying out this process includes a wire payoff; an inlet brush station having two pairs of brushes that rotate in a direction opposite to that of the wire to remove oxide film therefrom; a coating device; a dryer; a cooler; a drawing machine; first and second outlet brush stations each having two pairs of brushes that rotate in a direction opposite to that of the wire to remove residual drawing compounds therefrom; and a wire take-up device.

Abstract:

A stainless steel "fish tape" is disclosed. The tape is characterized by a steel formulation of 10 to 20 percent chromium, up to 18 percent nickel, up to 4 percent molybdenum, not more than 0. 9% carbon and no more than 0. 8% nitrogen. It is critical that the circumference of the tape relative to the cross sectional area of the tape be of a ratio of at least 1. 30 and preferably greater than 1. 55. In counter distinction to known prior art fish tapes which attempt to achieve a highly smooth surface, the tape of the instant invention is preferably roughened or abraded to improve the ability to carry for lubricants. The lubricant retaining characteristic functions both to reduce friction on insertion of the tape through a conduit and to leave traces of lubricant on the surface of surfaces which have been impacted against the tape whereby the wire which is then drawn through the conduit, will also be lubricated at the critical points in the conduit most likely to cause frictional contact with the wire. The ability to have a roughened surface, without increased corrosion, was clearly advantageous.
