Abstract A manufacturing method of low-relaxation prestressed high-strength steel wire includes mechanical descaling, cold rolling, wire-drawing spiral foring and stabilizing heat-treatment etc. the said method eliminates conventional pickling process, use cold-rolling instead of cold-drawing, thereby changes the deformation condition of metal simplities technological process, reduces cost and possesses the advantages of smaller occupied space, low power consumption, eliminate environmental pollution, and high product quality, and it can produce low-relaxation spiral steel wire and cold-rolled ribbed steel bar on the same production line.
