Accuracy and reliability of numerical simulation of hot rolling processes are dependent on a suitable material model, which describes metal flow behavior. In the present study, Gleeble hot compression tests were carried out at high temperatures up to 1300 °C and varying strain rates for a medium carbon micro-alloyed steel. Based on experimental results, a Johnson-Cook model (JC) and a Zerilli-Armstrong (ZA) model were developed and exhibited limitation in "Modeling and Simulation of Hot Rolling using Nonlinear Modeling and Simulation of Hot Rolling using Nonlinear Material Models. Results show specific distribution and history for strain and strain rate during round bar hot rolling process. Meeting Name. International Conference on Advances in Product Metallurgy of Long and
Modeling and Simulation of Mass Flow of Steel Plate/Slab during Hot Rolling Proceedings of the AIST 2nd International Symposium on the Recent Developments in Plate Steels (2018, Orlando, FL) "Modeling and simulation of viscoplasticity Subroutines accounting for developed viscoplasticity, dynamic recrystallization, and static softening were developed and implemented into a three-dimensional finite element model of round bar hot rolling. The combined JC and ZA model demonstrated better agreement with experimental data than other traditional models. Dynamic recrystallization occurred throughout the round bar during hot rolling and is Analysis of lateral metal flow-induced flatness deviations Jan 01, 2020 · Based on the principle of constant mass flow during rolling, a mathematical model for the flatness calculation and prediction accounting for lateral metal flow of the strip was established. The derived analytical model provided a quantitative transformation relationship of the three-dimensional deformation of the strip during the rolling process.
softening were developed and implemented into a three-dimensional finite element model of round bar hot rolling. The combined JC and ZA model demonstrated better agreement with experimental data than other traditional models. Dynamic recrystallization occurred throughout the round bar during hot rolling and is significantly influenced by the plastic Research on modelling and optimization of hot rolling Jul 26, 2018 · The model is closer to the actual hot rolling process. Based on this, the SA-MOPSO model is introduced into the CPS real-time mapping, and a double-flow digital twin agent is established to achieve simulated hot rolled steel production plan scheduling. Roll separating force in hot rolling under grooved rolls Finite element modeling and simulation of hot rolling under grooved roll has been carried out using commercial finite element based software ABAQUS® to compute roll separating force at rolling stand # 3 of Wire Rod Mill, TATA Steel Ltd. Online measurement of rolling load has been carried out using load cell for validation of simulation results.
Modeling and Simulation of Mass Flow during Hot Rolling Low Journal of Manufacturing Processes (2021) Shouvik Ganguly, X. Wang, K. Chandrashekhara, Mario F. Buchely, et al. Simulation of Thermal Phenomena in Reverse Strip-Rolling In the reverse hot strip rolling, the coiling and uncoiling of the strip leads to unstable conditions during the forming process. Both the temperature of the strip and the dwell time in the coil vary and influence the microstructure evolution passing in the coil during reverse rolling. It makes the design of this process difficult. Therefore, development of the temperature model for the (PDF) Modeling and Simulation of Mass Flow of Steel Plate In the case of hot strip rolling, the simulation predicts that material flows from the sides to the top and bottom surfaces during edging. The top and bottom surfaces were then rolled flat.
