RAIL THERMAL TREATMENT PROCESS |
摘要 |
A method for the thermal treatment of rails, in particular of the rail head, in which cooling is carried out in a cooling agent that contains a synthetic cooling agent additive, and starting at temperatures above 720.degree.C. The treatment is carried out by immersion in the cooling agent until withdrawal of the immersed areas occurs, at a surface temperature between 450 and 550.degree.C which results without temperature equalization across the entire cross-section, thereby avoiding hardening of the rail web whilst maintaining an optimal cooling rate for the rail head. |
