Numerical Simulation and Experimental Investigation of the High‐Speed Rolling Process for High‐Carbon Steel Wire Rods

High‐carbon steel wire rods are widely used in prestressed steel wires, springs, and tire cords owing to their high strength and excellent fatigue resistance, and their performance strongly depends on the complex thermomechanical conditions during hot rolling and cooling. In this work, the deformation behavior and microstructural evolution of 82Mn steel during multipass hot rolling are systematically investigated through thermal simulation experiments and finite element modeling. Beyond conventional dynamic recrystallization (DRX) analysis, the present study emphasizes the novel integration of metadynamic and static recrystallization (MDRX/SRX) kinetics into the rolling simulation framework, addressing a gap in previous studies. Constitutive and recrystallization models, calibrated by experiments, are implemented within a segmented finite element scheme, which significantly improves computational efficiency compared with monolithic approaches. The evolution of temperature, grain size, and recrystallization behavior is analyzed under varying process parameters, and the simulations demonstrate that the average grain size is refined to 17.1 μm under the combined action of DRX, MDRX, and SRX. This work provides a reliable and efficient strategy for simulating and optimizing high‐speed wire rod production, supporting the design of processes for improved microstructural control and product performance.
