Abstract Numerical analysis, finite element analysis and laboratory experiments were used to study the influencing factors and wide spread model of deformation in high-speed wire finishing rolling, the coupling stiffness and stiffness model of modular finishing mill, and the control strategy of steel biting speed drop during high-speed rolling. The upgrade was made in view of long-term problems for poor stability and large fluctuation of product dimensional accuracy caused by inaccurate receiving and discharging profile in the finishing mill of stainless steel high-speed wire production line, the application of modular finishing rolling technology in stainless steel high-speed wire was realized through high adaptability pass system, high stiffness modular high-speed mill and high-speed rolling speed drop control technology. Aiming at the problem that the wire was easy to be scratched at climbing section, the sliding friction climbing guide groove was optimized into the rolling friction three roll guide groove, and the looper before finishing mill was changed into vertical looper. The production results show that the operation of modular finishing mill is stable, the vibration value of bevel gear box is less than 2.8 mm/s, the dimensional accuracy of outlet profile for finishing mill is more than 20% higher than that before the transformation, and the dimensional accuracy and surface quality of the final product are significantly improved.
