This invention relates to a hot-rolled wire rod for 2300MPa grade stranded wire and its manufacturing method. The method involves rolling high-Si, high-carbon components containing trace amounts of Nb into wire rods, followed by online molten salt isothermal toughening treatment. This process involves a pre-treatment molten salt stage followed by rapid cooling, transitioning the wire rod from an austenitic state to a sorbite phase, forming a structure dominated by sorbite. A subsequent molten salt stage further reduces the molten salt temperature and circulation rate, promoting the continued transformation of untransformed residual austenite into sorbite, followed by isothermal tempering and partial melting of sorbite lamellars. Finally, the wire rod undergoes slow cooling on a roller conveyor, resulting in a hot-rolled wire rod with a microstructure comprising tempered sorbite, ferrite, and melted sorbite. This achieves a tensile strength of 1530~1580MPa, a reduction of area of 35%~40%, and a mechanical property difference of ≤48MPa between different coils. This method balances material cost and production efficiency, eliminating the need for offline heat treatment and promoting efficient and stable production of ultra-high strength stranded wire.
