| 摘要 |
The invention relates to the iron and steel industry. In order to improve the physical and mechanical properties and ensure the straightness of a rail, the rail is preheated from the austenitization start temperature to the austenitization end temperature, then postheated by thermal cycling in the region of alpha-gamma phase transformations and subsequently cooled over its cross section to a temperature that ensures that a fine-grained pearlite structure is produced, wherein heating is controlled continuously and/or discontinuously. After cooling, self-tempering is carried out to relieve stresses, and the rail is cooled first to a temperature of <=250°C and then to a temperature below 60°C. The apparatus comprises induction heaters arranged at intervals with preheating and postheating zones, cooling modules with a unit for controlling and adjusting the cooling parameters, differential cooling devices and final cooling devices, and a self-tempering zone. |
