Abstract
The invention relates to a method and to a spraying apparatus () for the thermal surface treatment of a metal product (). The metal product () is conveyed in a transport direction (T) through a treatment section () of a spraying apparatus () equipped with cooling nozzles () while cooling fluid is discharged through the cooling nozzles () of the spraying apparatus () onto the surfaces of the metal product (), wherein the metal product () has—viewed in the transport direction (T) of the metal product ()—a front section () and a trailing rear section (). The cooling of the surfaces of the metal product () within the spraying apparatus () occurs in such a manner that the rear section () of the metal product () is cooled more significantly than its front section (). It is thereby achieved that an essentially uniform ferrite content forms in the material of the metal product () at a predetermined depth of the same over a longitudinal area extending between the front section () and the rear section ().
