A high-strength multiphase hot-rolled wire rod for 2330MPa grade stranded wire and its manufacturing method

This invention relates to a high-strength multiphase hot-rolled wire rod for 2330MPa grade stranded wire and its manufacturing method. The method involves rolling a high-carbon, Mo-containing wire rod into wire, followed by online molten salt mixing and quenching toughening treatment. The wire rod undergoes a preliminary molten salt treatment followed by rapid cooling, transitioning from an austenitic state to a mixed phase region of bainite and sorbite, forming a microstructure dominated by bainite and sorbite. A subsequent molten salt treatment increases the molten salt temperature, promoting the decomposition of untransformed residual austenite into sorbite, followed by isothermal tempering. Finally, the wire rod undergoes slow cooling on a roller conveyor, resulting in a hot-rolled wire rod with a microstructure consisting of tempered bainite and tempered sorbite, comprising a multiphase microstructure. This method enables multiphase microstructure control and online toughening, while maintaining production efficiency. The hot-rolled wire rod can achieve a tensile strength of 1563~1613MPa and a reduction of area of ​​29%~34%, eliminating the need for offline heat treatment during ultra-high strength stranded wire production and reducing the risk of wire breakage.
