Development of a method to determine the dependencies of load moments and elastic moments on element parameters during the rolling process for dynamical states of a drive system for the rolling machine- roller table

The article presents general dependencies for the design of the load torque of a hot-rolling mill stand with respect to the rolling parameters. For the analysis of the electromechanical system a computer-aided model of an induction asynchronous motor taking into account iron losses has been developed. A simplified version of the mathematical model of rolling for a single mill stand has been assumed. The calculation results have been presented as time dependencies. On the basis of the calculation results the characteristics of the rolling process with respect to the maximum values of the elastic moments on motor clutches and the clutch coupling the mill stand on the thickness of the rolled component as well as the dependency of the maximum elastic moments on the connections as well as the dependency of the average value of currents of mill stand stator on thickens of the rolled product are presented.
