Abstract
The rule that governs the steady state of tandem mills is that the volume of metal passing through each stand in a given time is the same. If the screw setting of the rolls or the speed of the motor on any one stand is altered so as to alter the flow rate, then the other stands must be capable of adjusting themselves to this disturbance with fixed screw and speed settings. They are able to do this because the mechanical parts of the mill are sufficiently resilient to permit the separation of the rolls to alter even though the screws are fixed, and because the characteristics of the motor drive are such that the mill speed may vary even though the speed setting is fixed. In this paper an attempt is made to relate the changes in interstand tension and finishing gauge which result from such a disturbance to the mechanical and electrical characteristics of the mill, and to predict the behaviour of tandem mills under various conditions.Keywords
