Abstract
The relevance of creating systems for on-line monitoring of the elastic moment on the spindles of rolling mill stands is substantiated. The main reason for continuous monitoring is the high dynamic loads that arise when the rolls enter the cage. Using the example of electromechanical systems of the plate mill 5000, it is shown that the amplitude values of the elastic moment on the spindles can exceed the rated motor torque by 2 or more times. The oscillograms of the speeds and torques of the main drive motors of upper and lower rolls (VGP and NGP), obtained during 19 passes of reverse rolling of a pipe billet, are considered. An opening of the speed control loop was noted due to reaching the torque limit, which leads to an increase in dynamic loads. The importance of calculating the spindle life automatically is emphasized. The structure of the developed information system for on-line monitoring of the elastic moment is considered. An observer circuit with a function for determining the exhausted resource is proposed. A controller has been developed for calculating the amplitudes of dynamic moments and the life of spindles in Matlab Simulink. A method for calculating fatigue loads based on the linear Palmgren-Miner hypothesis is presented. Analytical expressions and a curve of the dependence of the exhausted resource on the multiplicity of the moment during capture are obtained. An assessment is given for the service life of the spindles of the upper and lower rolls for a rolling cycle and for a month under real load. It is shown that the uneven distribution of spindle loads leads to a significant reduction in their service life and a difference in the predicted service life. Due to the large volume of information being processed, it is recommended to introduce cloud technologies using BigData capabilities.
