Abstract

A finite volume method model for prediction of the thermal camber of work rolls J. Chen, R. Winkler & G. Finstermann R&D Department, Linz, Austria Abstract An application of the finite volume method (FVM) in the field of strip rolling mills will be presented. The aim of the simulation is to predict the development of temperature distribution in a work roll and to determine the thermal camber accordingly. The FVM is used for treatment of heat conduction in the work roll with the consideration of different boundary conditions like heat transfer by contact with the strip and bearings, spray water cooling, convection and radiation to air, etc. The first part shows the treatments of the volume elements used in the FVM. A quasi 3-D model is applied. The roll is divided in two regions in radial direction to consider the typical compound roll structure. Part two gives the view of treatments of the different boundary conditions involved on the roll surface. A sub-model couple
