For continuous rolling mills one of the most important technical issues is to configure the speed interrelated stands line. The basic law when setting speed rolling of the group of sequentially connected mill stands is the constancy of the volume of rolled metal S1*V1=S2*V2=S3*V3=...=SiVi . Setting the desired coherent frequencies of rotation of the rolls carried by the mill operator with the drive control specific panel. The electric drive system driven Converter (TP) – DC motor (D) with independent excitation allows operation in two zones (nн>n>n0), which gives the possibility of rapid adjustment of speed of rolling, in violation of the law of constancy of volume rolled. Construction properties of different groups of stands (roughing, intermediate, finishing) can have a considerable effect on the dynamic interaction and, as a consequence, loads on the interconnected Electromechanical systems stands. To assess the interaction of Electromechanical systems of interconnected mill stands it is recommended to first conduct a research on mathematical models to identify the most loaded units with their further study on a real mill using the methods of thermal and vibration field.
