The punchless welding point detection system using laser diagnostics for continuous strip production line has been developed. At the entrance of the steel strip production line, the preceding and following coils are welded for continuous processing. The welding point detection and tracking of the position is essential for the setup change of various important processing facilities according to ...

The final hot strip profile is a superposition of the roll initial crown, the roll bending and flattening crown, the roll wearing crown and the roll thermal crown. In this research, linear regression models are proposed to predict the roll force, the roll wearing crown and the roll thermal crown using experimental data provided by Mobarake Steel Complex (MSC). The short beam theory based on ela...

This work presents improved technology for attaining high-quality rolled metal strip. The new technology is based on an innovative method to model both the static and dynamic characteristics of rolling mill deflection, and it applies equally to both cluster-type and non cluster-type rolling mill configurations. By effectively combining numerical Finite Element Analysis (FEA) with analytical sol...

Work roll thermal contour is one of the important factors for roll contour design and configuration in hot strip rolling, for which the temperature field calculation is a critical factor. To realize the work roll thermal behavior for 1450mm hot strip mill, the temperature field and thermal contour calculation model was built with finite different methods, and the genetic algorithm was introduce...

An Integrated Digital Image Correlation (IDIC) method has been applied to the cold rolling process, images clearly visualise geometry of roll bite and inlet zone. A key, novel finding is that despite using coils applying entry tension, strip can enter asymmetrically in mill. Moreover, it shown asymmetric feeding results an uneven lubricant film thickness between top bottom surface. detailed fee...

The authors discuss the combination of an Artificial Neural Network (ANN) with analytical models to improve the performance of the prediction model of finishing rolling force in hot strip rolling mill process. The suggested model was implemented using Bayesian Evidence based training algorithm. It was found that the Bayesian Evidence based approach provided a superior and smoother fit to the re...
