Identification of Possibilities of Controlling Plastic Processing Processes in Conditions of Complex Loading

The combination of different loads in the process of plastic deformation makes it possible to find sufficiently effective technological modes of deformation associated with the control of plastic shaping of the deformable metal. These approaches are manifested in the fact that it is possible to reduce the force load on the deformation site, or the implementation of processing in which it is possible to improve the quality of finished products, mill productivity. Therefore, the task of finding process parameters that allow you to control and influence the deformation center during rolling in a special way becomes urgent. The analysis of scientific and technical literature shows that such parameters can be impacts that, according to deformation and force loading, should not be comparable with the main load, due to which the process of plastic deformation is realized. In this case, the factor of unevenness of plastic deformation can be controlling if its loading on the deformation site is less than the main one. This work, carried out within the framework of grant № AP23488953, funded by the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan, presents experimental studies of the effect of asymmetric unevenness of plastic processing along the width of the deformation zone during rolling on the conditions of rectilinear movement of the strip in the deformation zone and the force characteristics of ensuring this movement. Experimental data show that the force effect on the deformation site from the unevenness of compression is significantly less than the main load, which gives reason to consider this type of loading as controlling. The imposition of unevenness of plastic deformation on the plastic treatment zone causes the appearance of additional regulatory stresses, which significantly affect the stress state of the deformation site as a whole.
