摘要

The deformation and stress behavior during shear-compression bonding of intermediate slabs was investigated, and a systematic evaluation index to quantify bonding quality and process efficiency was established. A finite element simulation model based on plastic deformation theory was developed to analyze the influence of key process parameters. Single-factor analysis and an orthogonal experimental design, combined with range and variance analysis, were employed to evaluate the significance and sensitivity of multiple parameters. A quadratic polynomial regression model was further constructed to describe nonlinear relationships between process variables and performance indices. The results indicate that edge width, overlap amount, reduction, reduction speed, and slab temperature are the dominant factors governing bonding quality. The optimal parameter combination was determined as an edge width of 30 mm, overlap amount of 3 mm, reduction of 20 mm, reduction speed of 60 mm/s, and slab temperature of 1060 °C. The proposed integrated approach provides a reliable basis for process parameter optimization and contributes to enhancing bonding performance and consistency in endless rolling operations.
