The temperature and stress fields developing in rolls during hot rolling
Journal of Materials Processing Technology, 2004Abstract 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 ...

A study on residual stresses in rolling
International Journal of Machine Tools and Manufacture, 1997Determination 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.

The influence of some rolling parameters on the residual stresses after rolling
Journal of Materials Processing Technology, 1996Abstract 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

Stress-Strain Analysis of Back-up Roll with Roll-Sleeve
Applied Mechanics and Materials, 2011The back-up roll with roll-sleeve was studied and simulated using the finite element analysis software Abaqus in this paper. The stress-strain field of back-up roll with different roll-sleeve thickness and different magnitude of interference were compared because these two parameters are of importance for us to guide the application of roll with sleeve.

Measurement of the Interfacial Stresses in Rolling Using the Elastic Deformation of the Roll
Journal of Engineering for Industry, 1987A new method to measure the frictional stresses and normal pressure in the roll gap during cold rolling, and experimental verification of this new method, are presented. The method overcomes many of the shortcomings of pin-type sensors. The elastic deformation of the roll itself is measured with strain gages, and is used to calculate the stresses ...

Thermal Stress Evolution of the Roll During Rolling and Idling in Hot Strip Rolling Process
Journal of Thermal Stresses, 2014This study examined a critical idling time for the roll to attain a target temperature prior to rolling the next strip in the hot strip rolling process. Thermoelastic finite element simulations were performed to compute the temperature evolution and resulting thermal stress variations of the roll during rolling and idling.

Thermal stresses in work rolls during the rolling of metal strip
Journal of Materials Processing Technology, 1999Abstract In the strip-rolling process, inadequate work roll cooling often produces high roll temperature and temperature gradients. High thermal stresses resulting from high temperature gradients are responsible for roll surface cracking and spalling.

Residual Stresses Induced by Cross-Rolling
Materials Science Forum, 2006Deformation by rolling induces in general a strong crystallographic texture, hence an important material anisotropy. This is a reason why the cross-rolling is sometimes applied in order to symmetrize the crystallographic texture. Such an operation modifies also residual stresses.
