“…John et al [13] developed a rolling force model to calculate the rolling force of each stand, and combined the rolling force calculated by the model with the roll wear model to better predict the strip shape. Milenin et al [14] established the elastic-plastic deformation model of hot rolled strip during laminar cooling and the deformation model in the strip coil.…”

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.

“…Further, in order to maintain the accuracy of calculations, a comparison was made of compressive stresses in the full model and in the loaded simplified model with the transfer of forces to the beam wall (Fig. 9, 10) [13,14,15,16]. According to the calculation results it can be unequivocally stated that the accuracy of the calculations in the simplified model is acceptable within 1%.…”

The objects of the article are: analyze the work of the main beams of the movable span of the drop-down system near the axis of rotation; analyze the stress-strain state of the main beams of the movable span of the drop-down system near the axis of rotation; analyze the acceptability of the normative methodology (SP) for calculating the stability of the wall of a continuous steel beam during the design and calculation of movable bridge of the drop-down system. A computational-mathematical model of the movable span of the drop-down system is developed in a modern computational software package based on the finite element method. The main disadvantages of the normative methodology (SP) for calculating the wall stability of a continuous steel beam which used in design and calculation of movable bridge of a drop-down system are presented.

“…Based on their results, the control strategy of the strip shape compensation was improved in actual production. Numeric analysis of residual stress evolution during cooling of coils was carried out by Milenin et al [94]. With their analysis, the authors predicted compressive residual stresses, even for small strip thicknesses, and tensile residual stresses inside the volume of the central part of the strip.…”
