Abstract The physical foundations and advantages of ring rolling are described. The materials science and technological processes of manufacture of products with its use are generalized. An analysis of the equipment of an automated ring rolling line was carried out, which showed that it is a complex and expensive technical solution. Moreover, the organization of the line with maximum load and efficiency is not included in the supplier’s tasks. The requirements for the maximum load of the line and its efficient operation have been determined. It is shown that the use of the experience of creating automated production of railway wheels when creating an automated production of ring blanks is impossible due to the need to ensure the production of rings of different structural shapes from different steel grades with different temperature ranges of plastic deformation and with different (from a hundred to several thousands) annual production programs. This requires the use of a different ratio of the radial and axial forces of the ring rolling, different technological equipment, taking into account different stiffness of the rings and their tendency to deformations during processing, transportation and cooling, a special development of mechanization means for readjustments. It is impossible to work out in advance all the technological options for the production of rings of different standard sizes on an automated line. In this regard, for the effective work of the complex, it is necessary to develop technological support and software for the manufacturing processes of each ring, to provide for the possibility of adjusting technological processes directly on the automated line with the participation of operators. On this basis, the tasks of technological support for the operation of the automated ring rolling complex at the OJSC “BELAZ” were formulated.
