A method for cooling a preliminary strip or strip of a metal strand in a hot rolling mill including work rolls, comprising the steps of:
- spraying a cooling agent onto the preliminary strip or strip;
- screening the preliminary strip or strip in an area of edges of the strip from influence by the cooling agent;
- and, deflecting the cooling agent in the area of the strip edges of the preliminary strip or the strip, wherein the cooling agent is deflected from the strip edges in an area of an inlet guide of a work roll.
A hot rolling mill, comprising:
- a preliminary train and a finishing train for rolling a preliminary strip or a strip of a metal strand with work rolls;
- lateral guides for guiding the preliminary strip or strip, the lateral guides being arranged in front of an inlet gap formed always by two work rolls;
- a cooling device for applying a cooling agent to the preliminary strip or the strip;
- and means for screening the strip edges of the preliminary strip or strip from the influence of the cooling agent, wherein the screening means are arranged in an area of lateral guides.
