Abstract (en)

[origin: EP0761829A1] The device cools a rolled prod. (1), e.g. steel strip, defiling in front of the device, and comprises a device (4) for putting under gaseous pressure at least one caisson (10) which is made up of several thin strips forming a conduit (11). Each strip (11) incorporates at least one outlet orifice (12) for the gas in the direction of at least one of the surfaces of the rolled prod. (1), the orifices (12) of each strip (11) being aligned in the transverse direction to the rolled prod. (1). Each space (13) sepg. two adjacent strips (11) has a depth (P) in a direction perpendicular to the surface of the rolled prod. (1) and a width (L), in the direction longitudinal to the rolled prod. (1) that are sufficient to allow the evacuation of the gas (5) without disrupting the outlet of gas from the adjacent strips. The relationship of the gas (5) flow in m<3>/sec. at the outlet of the assembly of orifices (12) of a strip (11) on the section (S) in m<2> of the space (13) sepg. adjacent strips is less than 20, this section (S) corresp. to a section in a plane perpendicular to the rolled prod. (1) and parallel to the direction of defilement of the rolled prod.. The depth (P) of the space (13) between adjacent strips is greater than 200 mm and pref. 300 mm. The distance sepg. adjacent strips (11) is 0.8-5 times the distance sepg. each orifice (12) of the same strip (11). Also claimed is a cooling device incorporating at least one of these cooling devices.
