Roll Separating Force an overview ScienceDirect

The roll separating forces obtained in a single-stage pass of 55% reduction and two two-stage passes of 14/39% and 20/33.6% reduction are given in Figure 15.4, measured when rolling the softer AISI 1008, deep-drawing quality steel. Figures 15.2 and 15.4 are quite similar. The dynamic response of the mill is also similar to the previously observed behaviour.

Roll separating force in hot rolling under grooved rolls

2017-1-23  Finite element modeling and simulation of hot rolling under grooved roll has been carried out using commercial finite element based software ABAQUS® to compute roll separating force at rolling stand # 3 of Wire Rod Mill, TATA Steel Ltd. Online measurement of rolling load has been carried out using load cell for validation of simulation results.

Evaluation of Estimates of Roll Separating Force in Bar

A systematic approach is presented to estimate the roll separating force in bar rolling. This force is the product of the contact area between the rolled material and the roll pass, the mean unit pressure on the roll and the average flow stress within the roll gap.

ROLLING MILL STAND SCREWDOWN POSITION

The total mill stand roll-separating force is determined by the sum of the component roll flattening force FF(N) caused by pressure exerted by the rolls touching beyond the work strip width and the component rolling force FT(N) predicted for deforming the strip to give the desired delivery strip thickness from a

2006-5-31  3.2 Line contact sensors Rolling is a process which has attracted much atten-tion in sensor development. Measuring the frictional force in the rolling direction is of interest and there has been development of a special set of ‘line sensors’ to measure the frictional force across the roll face. These are illustrated in Fig. 5.

A Comparative Study of Helical and Cross-Wedge

This paper presents two rolling technologies: cross-wedge rolling (CWR) and helical-wedge rolling (HWR). The two rolling processes were compared using the example of rolling a ball stud forging. The technologies were modeled in the finite element model (FEM) environment. Calculations were performed to obtain distributions of strain and the Cockcroft–Latham damage criterion.
