Vertical sizing equipment longevity extrapolation based on finite element analysis
Traditionally, rolling process is widely used to achieve width reduction in hot strip milling production. However, there've been some drawbacks about the conventional methods that cannot be ignored, such as dog-bone profile and seam-effect. While on the other hand, the new width reduction method-slab sizing process offers decisive advantages over the conventional edging process in response to the drawbacks mentioned above. The objective of this thesis is to simulate the sizing machine, identify the advantages of sizing process over edging process, and compare the performance of sizing machine under different boundary conditions. In order to achieve these goals, this thesis develops a numerical model for the vertical sizing machine under typical operation conditions and conducts a structural finite element analysis of the model. In addition, the simulation results are validated by the field inspection data. Finally, a prediction of the remaining equipment life is made based on the results of the fatigue analysis.
