A photoelastic examination of the stresses in rolls during rolling

Journal of Strain Analysis, 1969
Abstract The paper describes some experiments to determine the stress distribution in rolls during the rolling of pure lead. The rolls were made from a hard transparent resin and the isochromatics and isoclinics were recorded whilst rolling was in progress. From these recordings the stress distributions were obtained.

THERMAL STRESSES OF ROTATING ROLLS IN ROLLING PROCESSING

Journal of Thermal Stresses, 1989
In a modern rolling mill, proper roll cooling has been identified as a critical factor in the problems of excessive roll wear and poor surface finish of rolled product. In this paper, an analytical solution to determine the cyclic stresses produced in the roll is developed.

Analysis of Residual Stresses in Rolling Mill Rolls

1989
Modern rolling industry requires the use of integrated processes that demand better performances and a higher-reliability of rolling mill rolls. That is the reason why work rolls or back-up, solid or compound, have steel grades more and more alloyed and undergo harder thermal treatments to meet users requirements. Therefore, stresses appear that always

Analysis on Stress Characteristics of Rolling Body of Rolling Dryer

Advanced Materials Research, 2012
Rolling dryer is one kind of dryer device with large output. The characteristic of rolling body has great influence on the output of dryer. In the paper, with the finite element method, the stress distribution of body, bolt hole, man hole and modes of rolling body are obtained by static stress and modal analysis and study of acting loads on rolling ...

A study on residual stresses in rolling

International Journal of Machine Tools and Manufacture, 1997
Determination of residual stresses in rolled material is important for the design of product and process. Different approaches for determining them and difficulties associated with the methods are discussed. A simplified approach to find the longitudinal residual stress (stress in the direction of rolling) is proposed.

Residual stresses in rolling contact

Journal of Strain Analysis, 1969
The paper reports an experimental investigation into the residual strsses induced into cylndrical discs by the action of rolling-contact loads sufficiently high to cause some plastic deformation in the near-surface layers. A general method is first described for finding both circumferential and axial components of residual stress in ...

The temperature and stress fields developing in rolls during hot rolling

Journal of Materials Processing Technology, 2004
Abstract The authors review the existing literature on the temperature field due to a moving heat source/sink on the surface of a roll. Either questionable results or solutions requiring extremely extensive numerical calculations can be found. The application of the solution for the temperature field of a moving heat source as an analytical and ...

The influence of some rolling parameters on the residual stresses after rolling

Journal of Materials Processing Technology, 1996
Abstract A 2D analysis of the deformation process in the rolling gap is presented. Flat strip rolling is considered for a low carbon steel at a temperature of 1000°C. 2D — Finite Element models with a rotating workroll have been installed using the Abaqus/Explicit-Code. The workroll is modelled as a rigid body. The main subject of the analysis is to
