Abstract: The invention relates to a method and to a spraying apparatus (10) for the thermal surface treatment of a metal product (1). The metal product (1) is conveyed in a transport direction (T) through a treatment section (12) of a spraying apparatus (10) equipped with cooling nozzles (16) while cooling fluid is discharged through the cooling nozzles (16) of the spraying apparatus (10) onto the surfaces of the metal product (1), wherein the metal product (1) has—viewed in the transport direction (T) of the metal product (1)—a front section (4) and a trailing rear section (5). The cooling of the surfaces of the metal product (1) within the spraying apparatus (10) occurs in such a manner that the rear section (5) of the metal product (1) is cooled more significantly than its front section (4).

Abstract: A roller device assembly, in particular for forming a strand guiding section (100) of a casting machine includes at least two roller devices each having a cross beam (30) and at least one roller element (10) supported on the cross beam (30) by means of roller bearings (20, 22), wherein guiding means for at least three different media are provided in the cross beam (30).
