Method of ascertaining the magnitude of forces acting upon rolls in rolling mills
First Claim
1. A method of ascertaining the magnitude of forces acting upon a roll in a rolling mill, the roll having a main portion and journals at each end of the main portion, comprising the steps of establishing a plurality of deformation monitoring stations;
- distributing said stations in at least one of two directions including axially and circumferentially of the roll between the two axial ends of the roll; and
directly monitoring the extent of deformation of the roll as a result of the application of forces to the roll in the course of the rolling operation at each of said plurality of monitoring stations.

Abstract
The magnitude of forces which act upon the rolls in rolling mills can be ascertained by directly monitoring the extent of deformation of the rolls under the action of forces which are applied to the rolls in actual use of the rolling mill. The monitoring step includes measuring the extent of deformation of each roll at a plurality of different locations. The rolls are preferably made, at least in part of a high quality alloy known as X5 NiCrTi 25 15 which renders it possible to dispense with surface cooling of the rolls. The monitoring involves a determination of rolling force FN, of the horizontal component FH of rolling force, of the vertical component FS of rolling force, and of the angle gamma between the direction of action of the rolling force and the vertical.
