“…On the basis of these equations and the results of measurements of the injected air velocities in various zones and sections of the air cooling line at the mill 170 of PJSC «MMK», software was developed to simulate the process of air cooling of rolled stock on small-section wire mills [14]. With the help of this software, experimental modes for the production of wire rod with the required sorbitized structure were developed and tested at the mill.…”

In 2019, the air-cooling line of Mill 170 of PJSC MMK (Magnitogorsk Iron and Steel Works) was upgraded. The main task of modernization was to obtain wire rod sorbitized in the initial state. The use of such products makes it possible to abandon one intermediate heat treatment operation in the wire production process, and should also ensure the stability of the mechanical properties of the finished wire of the entire size range of OJSC MMK-METIZ. On the part of OJSC MMK-METIZ, the following high requirements were imposed on the uniformity of the mechanical properties of the wire rod obtained at the mill -no more than 40 N/mm 2 along the length of the convolution, 50 N/mm 2 along the length of the coil, 60 N/mm 2 within the melt. When analyzing samples of rolled products from steel grades 70-75 with a diameter of 5.5-6.5 mm, it was found that compliance with the requirements in the modes operating at the mill is difficult. By the order of PJSC MMK, as part of scientific research on the development of wire rod production technology using a digital twin of an air cooling line, a mathematical model was developed, the adequacy of which was proved by developing rolling modes based on it, followed by evaluation of the resulting product. Upon further analysis of the obtained rolled products, it was found that the products manufactured according to the new modes meet the requirements for uneven mechanical properties along the length of the convolution and the coil to a greater extent.

The task of simplifying the calculation of deformation of the rolls and the strip profile during rolling in a four-high (quatro) stand has been formulated and stated in the article. The design and computer experiment results on the basis of which nonlinear approximations have been obtained for simplified calculation of the transverse rigidity moduli of the roller unit of the quarto finishing stand of the wide - strip hot mill 2500 have been described. The calculation of the transverse rigidity moduli of the roller unit of the quarto finishing stand is performed depending on the rolling force and the regulating force.
