Abstract (en)
The present invention relates to a device for cooling a flat or long metallurgical product (1) of a given width in a cold rolling mill, comprising a header (8) provided with a means for supplying a liquid coolant, a header table (28) comprising a plurality of nozzles arranged according to a well-defined two-dimensional pattern (27) for creating low pressure coolant jets towards a bottom surface of the product (1), a means for locating said header table (28) at short distance of the product (1), so as to create a homogeneous highly turbulent liquid coolant cushion at low pressure on the surface of the product (1) in front of the header table (28), in the volume restricted by the product (1) and the header table (28), wherein the device further comprises means (15, 16, 17, 21, 30) for preventing coolant jets to be generated outside of the product (1) according to the width thereof and/or for preventing such coolant jets from splashing and from falling back onto a top surface of the product (1).
