ABSTRACT:
A continuous steel strand is surfaced by (i) passing the strand through an electrolytic unit to remove metal from the surface of the strand, (ii) inducing current in the strand without any direct electrical contact with the strand, and (iii) moving the strand through the unit such that a section of the strand undergoes processing within the electrolytic unit for an extended period of at least twenty-five seconds. Steel valve spring wire is processed by surfacing a strand in an electrolytic process in which no direct electrical contact is made with the strand, and heat treating the strand in a furnace of a kind in which there is no direct mechanical contact between any metal surface and the surface of the strand. The electrolytic unit has a series of electrolytic cells of the kind in which no direct electrical contact is made with the strand, and there is a mechanism for passing the wire through the electrolytic unit more than once. Another feature is a strand of steel wire longer than 100 feet in which the exposed surface is compositionally the same as the interior of the wire and the surface is substantially free of impurities and mechanically imparted scratches.
