RESIDUAL AND STRAIGHTENING STRESSES IN NEW ROLLED STEEL RAILS

EIGEN-UND RICHTSPANNUNGEN IN WALZNEUEN SCHIENEN

When a new rail is laid in the track, it should be realized that, as a rule, the permanent bearing capacity of the material of which the rail is made is more or less influenced by residual stresses due to temperature. The results of measurements show that residual stresses in new rails after rolling occur mainly during straightening and not during cooling. The extent to which these stresses exist and how they are distributed in the length of rail depend on the curve of the rail before straightening, the elongation limit of the material and the rail profile.
