“…Therefore, simulating the coiling process to predict the internal stress state of the coil is of great significance in reducing the occurrence of defects and improving the product quality. [11][12][13][14] The analytical method is the simplest and most efficient. Sims et al 15) simplified the coiling process into thin-walled cylinders nested layer by layer on a thick-walled cylinder and adopted the axisymmetric assumption.…”

When analyzing the strip coiling process, the finite element (FE) method is closer to the actual working conditions compared to the analytical method. However, due to the large number of strip elements and contact elements, it often leads to problems such as long-time consumption and nonconvergence. Meanwhile, traditional FE methods are still unable to solve the problem of additional contact deformation between layers. Therefore, in order to overcome the shortcomings of the above methods, the FE software MSC Marc is used to establish a strip coiling model. The distribution pattern of interlayer friction and contact stress are analyzed to propose a new step-by-step bonding FE model, which greatly reduces the computing time. Through laminated compression experiments, the variation curve between additional contact deformation and pressure is obtained.The curve is introduced into the gasket elements to consider the additional contact deformation between the layers, and the effect of additional contact deformation between the layers on the stress of the coil and the pressure on the mandrel is studied. Finally, the analytical solution is compared with the FE solution proposed in this paper, and the errors generated by the analytical method are analyzed.

“…The reason for the transverse bending of the strip as it passes through the deflection rolls in the annealing furnace is explained by Masui et al [21]. Qin et al [22] used the finite element method to study the mechanism of transverse bending of the strip during rolling and continuous annealing. The transverse bending of the strip in hot-dip galvanizing is calculated in ref [23].…”

Transverse bending, a common shape defect of hot-rolled strips, is generally controlled based on experience, which lacks quantitative study. This leads to some production problems such as difficult feeding and surface scratching in subsequent processes. Based on the principle of elastic mechanics, the mechanism of transverse bending in the process of uncoiling is studied and an analytical model is established. Then the relationship between transverse bending and influence factors, including the curvature radius of longitudinal bending, strip width and strip thickness, is obtained. The study indicates that the transverse bending is caused by longitudinal bending before uncoiling. And the strip width and the curvature radius of longitudinal bending have a great influence on the transverse bending but the strip thickness has little influence. The transverse bending diminishes nonlinearly with the increase of curvature radius of longitudinal bending and increases nonlinearly with the increase of strip width.
