Differential Analysis and Prediction of Planar Shape at the Head and Tail Ends of Medium-Thickness Plate Rolling

This paper aims to improve planar shape prediction accuracy in the rolling process of medium and thick plates. We present a model based on strip method that addresses limitations predicting variations at head tail ends rolled pieces. By analysing process, we introduce concept an imaginary longitudinal length difference represent characteristics effectively. change metal deformation zone, calculation formula for volume zone is derived. establishes relationship between piece zone. The plane end medium-thickness plate realized. experimental results confirm feasibility effectiveness proposed method.
