1. A novel 3D multi-stand coupled thermo-mechanical finite element (FE) model has been developed to study the influence of rolling force on strip shape during tandem hot rolling.
2. Results show that the strip crown increases with the rolling force at each stand, while the regulation efficiency of rolling force on the strip crown decreases continuously from F1 to F7.
3. Lateral metal flow and strip plastic rigidity have a coupled effect on the regulation efficiency of rolling force on the strip flatness.
The article “Influence mechanism of rolling force on strip shape during tandem hot rolling using a novel 3D multi-stand coupled thermo-mechanical FE model” is an informative and well-written piece that provides insight into how rolling force affects strip shape in tandem hot rolling processes. The authors provide evidence for their claims by citing previous research and validating their findings with industrial experiments. The article also presents both sides of the argument equally, exploring both positive and negative effects of rolling force on strip shape.
However, there are some potential biases in the article that should be noted. For example, it is possible that some of the data used in this study may be incomplete or inaccurate due to limitations in experimental methods or data collection techniques. Additionally, there may be other factors not considered in this study that could affect strip shape, such as roll wear or lubrication conditions. Finally, it is important to note that this study only focuses on one particular type of hot rolling process; further research is needed to determine if these results can be applied to other types of hot rolling processes as well.
