Title:
PROCESS FOR PRODUCING WIRE FOR BEAD CORD, BEAD CORD, AND VEHICLE TIRE
Document Type and Number:
WIPO Patent Application WO/2007/123081
Kind Code:
A1
Abstract:
In producing a wire for bead cords, a steel wire is first descaled. Subsequently, the
steel wire descaled is subjected to a chemical conversion coating treatment by
electrolysis to form a phosphate coating film on the steel wire. This steel wire,
which has undergone chemical conversion treatment, is subjected to dry drawing
and then to wet drawing as finish drawing to obtain a wire for bead cords. The drawing
operations are conducted so that the zinc phosphate coating film, which has corrosion
resistance, remains on the surface of the wire for bead cords.
