Abstract
The issue of using the parameters of vibrodynamic processes in rolling mills, primarily during the gripping of the strip by rolls, to determine the technical condition of the equipment is considered. Examples of typical transient processes of the moment of elastic forces on the spindles and the motor shaft and vibration of the equipment along the drive line are noted. Examples of developed methods of diagnosing the actual technical condition of rolling cage equipment are provided. In particular, with the use of such a new indicator as the time delay of the reaction of the areas to the impact load in the cage. On the basis of the obtained industrial measurements and mathematical modeling, the directions for the search and development of new methods and methods are proposed and substantiated. It is recommended to use the correlation fields constant moment - the maximum moment of elastic forces during strip capture, coefficients of variation, purposeful creation of special modes of rolling and operation of equipment and installation of continuously operating strain gauges and use of regular sensors.
