  • Method for reducing internal stresses of roller straightened rails
    Patent number: 4659398
    Abstract: The present invention relates to a process for reducing internal stresses of roller straightened rails. After the straightening operation the rail web portion is heated for a short time to temperatures ranging between 200.degree.-700.degree. C., preferably between 350.degree.-500.degree. C., and after reaching the desired temperatures the rail is cooled by air to room temperature. For the purpose of heating the rail is continuously conveyed in front of the heating apparatus.The inventive process permits to reduce internal stresses in the rail head and base portions to a value of less than 50 N/mm.sup.2 thus ensuring increased rupture strength of the rail.
