| Abstract Scope |
In the steel plate processing consisting of hot rolling and multi-stage cooling, unexpected plate deformation can occur. This deformation mainly arises due to thermal contraction/expansion and phase transformations during the thermo-mechanical process. This study aims to evaluate the plate deformation during the hot rolling process followed by multi-stage cooling using thermo-mechanical-metallurgical finite element (FE) analysis. The phase transformations are modeled based on the Johnson-Mehl-Avrami-Kolmogorov (JMAK) kinetics along with the additivity rule and the Koistinen-Marburger equation for diffusion-controlled and diffusionless martensitic transformation, respectively. Thermal boundary conditions are simplified based on the experimentally measured thermal histories and the relationship between water flow rates and heat transfer coefficients. The predictive capability of the proposed model can be validated by comparing the measured plate deformations under differential cooling between the upper and lower parts of the plate. |
