Special Issue Information

Dear Colleagues,

Rolling is considered to be one of the most efficient formation processes. It plays an important role in the automated production of many metal foils or strips. The shape and properties of material are important criteria used in the rolling process to evaluate strip quality. Therefore, many factors, such as the metal flow characteristics, the shape detection and control, the work hardening, as well as the size effect, must be researched in detail. According to these mechanisms, there may be opportunities for some better rolling methods. For example, asynchronous rolling, electro-plastic rolling, extrusion rolling, and warm rolling are often used to produce the foils of difficult-to-deform metals. All in all, newer and better processes should be continuously studied by researchers. This will contribute to the quick industrial application of key technologies and the industrialization of rolling products. All these aspects deserve special attention.

This Special Issue provides an excellent opportunity to publish theoretical and experimental studies on metal rolling, especially on alloy steel, magnesium alloys, amorphous alloys, high-entropy alloys, etc. Any new findings on this topic are welcome, such as metal flow rules in asynchronous warm/hot/cold rolling processes, microstructural evolution in special rolling processes, shape detection and shape control, etc.

In response to the challenging difficult-to-deform of magnesium foils, a high-efficiency and high-precision electro-rolling temperature field coupled model is established. This model is designed to simulate the non-annealing electric rolling (NAER) process of Mg foils under conditions of high current density, rapid temperature rise rates, and large temperature gradients. Firstly, a coupled temperature field difference model for the guide roller, roll, and Mg foil is established, based on the equipment for NAER and the electrification conditions. The Joule heat, distortion heat, and friction heat in the electric rolling process were precisely considered. Secondly, considering the peculiarity of the heat source and the heat transfer mechanism during NAER, the influence of the dynamic boundary conditions on the instantaneous temperature of the Mg foil was analyzed, which was closer to the actual situation. The experimental results show that the original model can accurately simulate the transient temperature change in Mg foils during NAER, and the error between the predicted value and the measured value is within 7.1%. According to the calculation of the model, the microstructure of completely recrystallized magnesium foil with a grain size of 4.61 μm and a texture strength of 11.3 can be obtained at an inlet temperature of 250 °C.
