Roll force measurement ABB

ABB’s Millmate roll force system is the perfect choice for measuring roll force in both hot rolling and cold rolling mills, thereby achieving correct roll gap settings and force distribution. The system is proven to be exceptionally robust and resilient to high forces as well as aggressive mill agents. The load cells are calibration free, can withstand overloads up to 7 times the nominal

24/12/2018· The Three High Rolling Mills comprises of a roll stand with three parallel rolls one above another. The adjacent rolls rotate in the opposite direction to pass the material between the top and middle roll in single direction, and the bottom and central roll in the opposite direction. The workpiece is rolled on both forward and return passes.

1. Hot rolling and rolling defects: 1.1 Front and back

Roll force is equal to roll pressure multiplied by area of contact between roll and work. F = -----5.5 If friction is ignored, we can write an approximate expression for roll force as: F = Lw -----5.6 With friction: F = Lw (1+ ) -----5.7 Where, is given by: (h. o +h. f)/2 . 1.4 Roll torque and power: Roll torque can be estimated from the rolling force. Torque is equal to force multiplied by

Load Analysis of Rolls in a Rolling Mill: A Comparison of

Keywords: Rolling mill, Roll load, Robert, strain gauges I. INTRODUCTION Rolls are the the most basic part in a rolling mill. Forces because of deformation of plate are transmitted to them directly, and then are transmitted to other parts like bearings, housings, etc. Rolls failure is a common problem faced by the rolling industry. It occurs due to overdraft which causes overloading, and also

Rolling Process: Working, Application, Defects, Type of

Three-High Rolling Mills: In this mill, the three rolls stand in parallel one by others. The rolls are rotating in opposite directions. In this mill, between the first and the second rolls, the material passes. If the second roll rotates in a direction then the bottom roll rotates in another direction. The material is rolled both in forward and return in three high rolling mills. At first, it
