This invention relates to a hot-rolled wire rod for 2330MPa grade stranded wire and its manufacturing method. The method involves rolling high-carbon, high-silicon Cr-V wire rods 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 predominantly sorbite microstructure. A subsequent molten salt stage further increases the molten salt temperature and reduces the molten salt circulation rate, promoting the continued transformation of untransformed residual austenite into sorbite and isothermal tempering, while also promoting 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 consisting of tempered sorbite, ferrite, and melted sorbite. This method controls material costs, achieving a tensile strength of 1558~1608MPa and a reduction of area of ​​34%~39%, while balancing production efficiency and energy consumption. It eliminates the need for offline heat treatment, enabling efficient and stable production of ultra-high strength stranded wire.

This invention provides a method for preparing large-diameter polyphenylsulfone (PPS) monofilaments, comprising the following steps: mixing PPS and a lubricant and then performing melt extrusion to obtain a melt; extruding the melt through a spinneret to obtain nascent monofilaments; sequentially subjecting the nascent monofilaments to oil bath cooling, drawing, and winding to obtain cooled and shaped nascent monofilaments; and sequentially subjecting the cooled and shaped nascent monofilaments to slow drawing and heat setting to obtain large-diameter PPS monofilaments; the slow drawing speed is 3–5 m / min. The addition of a lubricant in this invention improves the flowability and extrusion stability of PPS, preventing melt fracture during extrusion. The subsequent oil bath cooling improves the surface smoothness of the cooled nascent monofilaments, which is beneficial for subsequent drawing. The slow drawing speed allows for slow cold drawing of the nascent monofilaments, which not only enables molecular chain orientation but also prevents filament breakage, thereby obtaining large-diameter PPS monofilaments.
