Abstract - A beam of length 100 m with the profile of a railway rail lies on a cooling bed during the cooling process after hot-rolling. The analytical solution for the distribution of the frictional forces along the beam leads to problems which are up to now unresolved. Therefore, the Finite Element Method is used to compute both the residual stresses in longitudinal direction and the deformations of such a horizontally lying long beam. The frictional forces between the beam and the cooling bed have great influence on the remaining residual stress state. A cold beam shows substantial differences in the residual stress distribution between the middle and the end part.
