The invention relates to a method and a device for heat treating profiled rolling stock, in particular rails. For improving the use properties it is provided to straighten the rolling stock at a temperature of at most 1100°C, however at least 750°C, during plastic formation and, in a first step for cooling, to perform cooling with locally even cooling intensity to a temperature, in particular of 5 to 120°C above the AR3 of the alloy, and in a second step to remove heat from the rolling stock in the longitudinal direction at a locally equal but, viewed in cross section, circumferentially different intensity, wherein increased cooling intensities are assigned to areas of high mass concentration, in which areas a fine pearlitic grain free of martensite is formed, after which cooling to room temperature takes place. A device of the invention is distinguished by a stand-by area (A), a cooling treatment area (B) and a final cooling area (C) for profiled rolling stock.
