HEAT-TREATMENT METHOD FOR RAILS |
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, starting at temperatures above 720° C. The treatment is carried out by immersion in the cooling agent until withdrawl of the immersed areas, courses, at a surface temperature between 450 and 550° C. results without temperature equalization across the whole of the cross-section, section, there by avoiding hardening of the rail web whilst maintaining an optimal cooling rate for the rail head. |
