“…Suguhiro et al [17] developed a new method of high-precision online shape prediction model based on matrix model by taking rolling force and tension into account through experiments and finite element analysis. Garber et al [18] developed the calculation program of the main drive power of the hot rolling wide strip mill, which reduced the contact stress of the roll by redistributing the tension reduction and tension between the stands and increasing the temperature of semi-finished products. Li et al [19] proposed a shape preset strategy to allocate the crown of the finishing mill according to the size of the shape control domain of each stand.…”

To reveal the shape change characteristics during the rolling process of the four-high hot continuous rolling mill, a three-dimensional finite element model was built with the wheel steel 380CL as the sample. The equivalent stress field, strain field, and displacement change of thickness of the wheel steel in each rolling process were analysed, and the field measurement and verification analysis were carried out. Results show that the equivalent stress, strain and thickness displacement of the strip edge gradually increases with the rolling, respectively. Reasonable tension before and after loading can effectively reduce the equivalent stress in the deformation zone and the rolling pressure required during rolling. The difference between the simulated rolling outlet thickness of 7.61 mm and the field measured thickness of 7.69 mm is small, which verifies that the calculation accuracy of the finite element is high. The conclusions obtained in this study provide a basis and reference for the development of similar wheel steel rolling calculation model.

“…The effect of rolling parameters on the rolling properties has not yet been fully understood. The effect of rolling parameters on temperature [7], friction stress, rolling force [8,9], and effective stress and strain [10] were discussed. Friction is the reason for the rolling process to actually take place.…”
