Strip Quality

Strip shape is an important factor affecting the strip quality significantly during cold rolling of thin strip. In the paper, finite element simulation models of the strip shape in cold rolling for both symmetrical and asymmetrical rolling cases were successfully developed. The strip edge drop and the effect of the rolling force on the strip shape (the thickness distribution along the strip width) have been obtained. The developed finite element model has been verified with the experimental value, which shows they are in good agreement. The obtained results are applicable to control the rolled thin strip shape during cold rolling practice.

Element Analysis

Cold rolled thin strip has received a great deal of attention through technological and theoretical progress in the rolling process, as well as from researchers who have focused on some essential parameters of strip such as its shape and profile. This paper describes the development of a 3-D finite element model of the shape of thin strip during cold rolling to simulate the cold rolling of WCS (work roll crossing and shifting) in asymmetric rolling. This finite element model considers the asymmetrical rolling parameters such as variations in the diameters of the rolls and the crossing angle as the work roll shifts on the strip during cold rolling. The shape and profile of the strip are discussed in the asymmetrical and symmetrical rolling conditions, while the total rolling force and distribution of stress are discussed in the case where the roll cross angle and axial shifting roll changes. The results can then be used to control the shape and profile of thin strip during rolling.

In order to research the forming process of H-beam, based on the large H-beam production line of HN600x200, the Standard and Explicit solver of ABAQUS are synthetically used to establish finite element model for rolling process and inter-pass thermolysis process. The reciprocation multi-pass rolling process simulation procedure based on the re-meshing technology is used to simulate the whole production process form blanks to finish products, and the continuity of data is ensured. Based on the simulation results, the deformation and rolling force of the roller as well as the metal flowing law and temperature field of workpiece are discussed emphatically. The results clearly show that the displacement of roller contains the elastic deformation and the deflection, and the counterforce of left adds to the counterforce of right is about equal to the resultant force. The simulation results are compared with the measuring results, which proves the correctness of simulation.

Profile Control

Controlling cold strip profile is a difficult and significant problem has been found in industry during thin strip rolling. At present choosing the new type of strip rolling mill is the one of main methods to control the strip shape quality in cold rolling. The influences of rolling process parameters such as the work roll cross angle and work roll shifting on the strip shape and profile of thin strip are recognised throughout this study. The results show that the roll crossing and shifting is efficient way to control the strip shape. The increase of the work roll crossing angle would lead to improve the strip profile significantly by decreasing the exit strip crown and edge drop. The strip profile would be enhanced if the axial roll shifting was increased. Moreover, the total rolling force was analysed in detail by changing the roll cross angle and axial shifting roll.

Operation Platform

Based on Abaqus/Explicit operation platform, a finite element model of Yantai Baosteel Φ460mm PQF mill was established to study the mass scaling factors influence of the rolling process. The experimental results show that mass scaling factor has smaller impact on the temperature. Distortion of rolling force and Mises stress gradually occurs with the increase of mass scaling factor. Under the premise of ensuring the calculation accuracy, a best mass scaling factor is found to improve the computational efficiency of the model.
