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.

This invention proposes a fully electro-melting vertical kiln basalt fiber melting channel, including an electro-melting control system and a furnace body. The furnace body, from one end to the other, sequentially includes a melting zone, a clarification and homogenization zone, and a working zone.

This invention relates to a high-strength multiphase hot-rolled wire rod for 2360MPa grade stranded wire and its manufacturing method. The method involves rolling the wire rod into a high-carbon Mo-V system, followed by online molten salt weak quenching and toughening treatment. The wire rod undergoes rapid cooling in the initial molten salt treatment, 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 allows for online control of the microstructure and toughness, achieving a tensile strength of 1574~1627MPa and a reduction of area of ​​28%~33%, reducing fluctuations in mechanical properties and balancing material cost and production efficiency.
