Roll Separating Force an overview ScienceDirect

Typical roll separating force and roll torque data, as a function of the reduction and at various roll surface speeds (20 and 160 rpm, leading to surface velocities of 262 and 2094 mm/s) are shown in Figures 9.19–9.21, respectively. The lubricants and the emulsions used are also indicated in Figures 9.19–9.21. As expected, the roll forces and the torques increase as the reduction is increased, in a fairly linear

The calculation of roll torque and roll separating force

2012-4-1  Abrinia and Fazlirad pointed that obtaining a full analytical solution for the roll torque and separating force has been one of the most difficult problems in the analysis of plate rolling because of the difficulties in formulating the governing equation . Moreover, few attempts have been reported to predict the broadside rolling force in the extra-thick plate mill since the contact arc-to-height ratio (called

Rolling mill gauge control WESTINGHOUSE

The roll separating force is measured by a load cell or other suitable force detecting device operative with the roll stand. The roll opening position is then controlled to balance roll force changes from a reference or initial lock on value and thereby to hold the loaded roll opening at a substantially constant value.

Prediction of Plate Crown during Aluminum Hot Flat

The roll deflection during hot rolling can result in uneven thickness distribution across the width of a plate (crown). A conventional rolling mill is equipped with bending systems that can control this convex shape of the plate. However, the determination of the proper bending load is very complicated as the plate crown is influenced by the rolling conditions.
