Special Issue Information

Dear Colleagues,

The development of high value-added plate and strip products such as lightweight, high-strength steel; ultra-high-strength steel; stainless steel; and electrical steel is of great significance for upgrading the steel industry and achieving dual carbon goals, whether aimed at meeting major national strategic needs, such as defense and aerospace, or meeting the requirements of national economic industries such as power electronics and equipment manufacturing.

With the development of high-quality strip production towards high strength and thinning, rolling and control difficulties have become increasingly prominent, leading to abnormal equipment operation statuses and the degradation of product functional accuracy, causing serious value losses and bottlenecking product development and efficiency improvement. The requirements for lubrication technology and friction conditions are very strict, especially in the continuous rolling process of high-strength thin plates. Moreover, the thermal coupling effect resulting from temperature, lubrication, friction, stress, and strain is more complex, resulting in inaccurate prediction of force and energy parameters, difficulty identifying key indicator parameters, and low feedback control accuracy.

Thus, focusing on interface friction and lubrication, research on the dynamics and stability of the rolling process of plate and strip products can reveal the evolution law and instability mechanism of the dynamic behavior of these systems, which has important theoretical significance and engineering value for the prediction and maintenance of equipment performance, traceability diagnosis of product quality, and optimization of process decision-making. Moreover, it has a positive effect on improving the intelligence of core plate and strip production processes.

This Special Issue (“Intelligent Rolling Dynamics: Enhancing Friction and Lubrication in Plate and Strip Mills”) aims to collate contributions from rolling process dynamics, rolling lubrication and friction, etc., to enhance the cross integration of knowledge from these two fields and deepen our understanding regarding interfacial friction and rolling dynamics. Contributions are welcome from all scientists working in rolling processes, lubrication, friction, dynamics, and related areas.

With the development of rolled steel strips towards higher strength and thinner thickness, negative forward slip has been frequently observed during the process of cold rolling, and this phenomenon closely related to interface is believed to seriously influence rolling stability. However, the existing classic forward slip models are limited to calculating positive forward slip values and cannot reflect negative forward slip effects. Therefore, in this paper, based on BLAND-FORD forward slip theory, a novel modified forward slip model capable of predicting negative forward slip is established and verified, in which the corresponding flattened curve is characterized and a compensation coefficient related to actual tension and coil number is supplemented. Then, a dimensionless sensitivity factor is defined to compare and analyze the influences of various parameters on forward slip through the modified model, in order to pick a more effective and reasonable regulation approach. Finally, an idea of keeping stable forward slip through dynamic tension regulation is suggested and applied in the actual rolling process, and it is drawn that this strategy can be used to avoid fluctuations of process parameters and suppress mill chatter. As a result, the presented modified forward slip model can identify both positive and negative forward slips and is helpful in regulating the interface state and improving the stability of the rolling process.
