Abstract:
1. A device for influencing temperature distribution over a width of a slab or a strip ( 33 ), comprising: at least one cooling device in a rolling mill, said cooling device that has nozzles ( 14 ) for applying a cooling medium on the slab or on the strip ( 33 ), wherein the nozzles ( 14 ) are at least one of arranged and actuated widthwise so that the cooling medium is applied 1) at positions at which an elevated temperature is determined, or 2) in a controlled fashion in dependence on a measured strip contour so that the strip contour approximates a desired target contour more closely, at least one of the nozzles being positionally adjustable relative to the width of the slab or the strip, wherein the nozzles are mounted on two opposite a lateral guides that guide lateral sides of the slab or the strip, the guides are laterally adjusted along the direction of the width so as to provide widthwise adjustment of the nozzles, wherein shapes or types of the nozzles differ widthwise with respect to at least one of cooling medium quantity and spray pattern.
