Numerical Simulation as a Tool for the Study, Development, and Optimization of Rolling Processes: A Review
Rolling is one of the most important processes in the metallurgical industry due to its versatility. Despite its inherent advantages, design and manufacturing by rolling still rely on trial-and-error-based optimizations, which reduces its efficiency. To minimize the cost and time spent on the development of new rolling schedules, various analytical and numerical methods have been used in recent years. Among other alternatives, simulations based on the finite element method (FEM) are the most widely used. This allows for the analysis of the feasibility of new rolling schedules considering metal alloys with different characteristics, process conditions, or the creation of new operations, as well as the optimization of existing ones. This paper presents a literature review including the latest developments in the field of numerical simulation of rolling processes, which have been classified according to the type of rolling into the following categories: flat rolling, shape rolling, ring rolling, cross-wedge rolling, skew rolling, and tube piercing.

Plastic Deformation Mechanism of High Strength and Toughness ZK61 Magnesium Alloy Plate by Multipass Horizontal Continuous Rolling
ZK61 magnesium-alloy plate with high tensile strength and elongation is obtained by combined multipass symmetric hot rolling and asymmetric warm rolling. Deformation history considering varying strain rate obtained from the macro-finite element analysis of the selected passes are introduced into the viscoplastic self-consistent model (VPSC) as initial boundary conditions for macro- multiscale and micro-multiscale coupling analysis. VPSC simulation results show that in the initial stage of rolling deformation, the basal slip is the dominated deformation mode, supplemented by prismatic slip and pyramidal slip. With increased rolling strain, the pyramidal slip presents competitive relationship with basal slip, and the activation amount of 101—1 compression twins is limited. During asymmetric rolling, the basal slip is dominant, followed by the pyramidal slip. Experimental results show that the basal texture is gradually strengthened after symmetric rolling, and grain size is refined due to the activation and recrystallization of twins. Asymmetric rolling makes the basal texture deflect 10° to the rolling direction and further refine the grain size. With the ongoing of symmetric rolling, the mechanical anisotropy of the plate weakens, and the yield strength, tensile strength, and plasticity of the material improves. In particular, after asymmetric rolling, the tensile strength in the RD and TD directions of the plate reaches 391.2 MPa and 398.9 MPa, whereas the elongation reaches 19.8% and 25.5%.

Stabilization of Strip Thickness at Nonstationary Stages of Cold Rolling in Multistand Rolling Mill for Shortening End Sections of Metal Strips with Thickness Outside Tolerance Space
This article considers the reduction in strip thickness variations and lengths of sections with thickness outside the tolerance space by controlling the draft of end strip sections at nonstationary stages of the cold rolling on machine stand 1400 at the shop for nongrain-oriented steel (SNGOS) of PAO NLMK. The article also provides comparative data on the thickness and length of end strip sections outside the tolerance space, that are rolled at the existing method of mill setting and adjusting strip thickness according to the developed method.

Vibration Characteristics of Hot Rolling Mill Rolls Based on Elastoplastic Hysteretic Deformation
Based on the analysis of the influence of roll vibration on the elastoplastic deformation state of a workpiece in a rolling process, a dynamic rolling force model with the hysteresis effect is established. Taking the rolling parameters of a 1780 mm hot rolling mill as an example, we analyzed the hysteresis between the dynamic rolling force and the roll vibration displacement by varying the rolling speed, roll radius, entry thickness, front tension, back tension, and strip width. Under the effect of the dynamic rolling force and considering the nonlinear effect between the backup and work rolls as well as the structural constraints on the rolling mill, a hysteretic nonlinear vertical vibration model of a four-high hot rolling mill was established. The amplitude-frequency equations corresponding to 1/2 subharmonic resonance and 1:1 internal resonance of the rolling mill rolls were obtained using a multi-scale approximation method. The amplitude-frequency characteristics of the rolling mill vibration system with different parameters were studied through a numerical simulation. The parametric stiffness and nonlinear stiffness corresponding to the dynamic rolling force were found to have a significant influence on the amplitude of the subharmonic resonance system, the bending degree of the vibration curve, and the size of the resonance region. Moreover, with the change in the parametric stiffness, the internal resonance exhibited an evident jump phenomenon. Finally, the chaotic characteristics of the rolling mill vibration system were studied, and the dynamic behavior of the vibration system was analyzed and verified using a bifurcation diagram, maximum Lyapunov exponent, phase trajectory, and Poincare section. Our research provides a theoretical reference for eliminating and suppressing the chatter in rolling mills subjected to an elastoplastic hysteresis deformation.

Rolling force prediction in cold rolling process based on combined method of T-S fuzzy neural network and analytical model
In the cold rolling process, inaccurate rolling force settings and the resulting strip thickness fluctuations and other quality problems occur, reducing the yield and product quality. To improve the accuracy of rolling force prediction, this paper proposes three methods to combine a T-S fuzzy neural network and rolling force analytical model based on their advantages and characteristics, to construct a combined rolling force prediction model, and to fully utilize the features and benefits of each model for rolling force prediction. The model’s performance is evaluated by selecting the mean absolute error (MAE), mean absolute percentage error (MAPE), and root mean squared error (RMSE). The model experiments with historical production data obtained from industrial sites. The experimental results show that the combined prediction models have a more robust rolling force prediction capability than the T-S fuzzy neural network model alone, especially the combined form of using the calculated value of the rolling force analytical model as the input to the T-S fuzzy neural network without destroying the self-learning of the rolling force analytical model, which has better calculation accuracy and reliability for rolling force than other models. The model can provide an essential reference for the online prediction of cold rolling force and high precision rolling production and has high usability.
