INVESTIGATING THE EFFECT OF THERMOMECHANICAL TREATMENT ON THE PROPERTIES OF RAILS

A new method has been worked out at Kuznetsk Metallurgical Combine for rolling rails, in which provision is made for a high degree of deformation of the section head in a universal pass, with subsequent hardening of the rolled surface of the rail head. The possibilities of the new method of strengthening are demonstrated. The rolling of rails in the universal pass with the application of thermomechanical treatment leads to an improvement (refining) of the structure and to enhanced mechanical properties. The strength properties of the rails are at the level of oil-quenched rails, tempered at 450 degrees C, and the plastic properties are higher.
