Abstract (en)
[origin: EP0069616A1] 1. A device for high-speed cooling of steel-wire turns (6) in the heat of a hot-rolling mill, of the type comprising a conveyor consisting of a number of air-blast boxes (1) the upper wall of which is provided with middle (5) and side openings (3), (4) called "louvres" through which air is blown onto the wire turns (6) which move above the upper wall (2), the forward portion, in relation to the direction of motion of the turns of each said louvre including a "baffle plate" (9), sloping towards the inside of the air box (1) and also to the rear portion of the louvre, a device characterized in that, at least for some of the louvres, the angle of slope (alpha) of the baffle plate (9), in relation to the upper wall (2) of the air box (1) is less than 20 degrees and that said baffle plate (9) is extended by a shorter portion (10) which is parallel with the upper wall (2) of the air box (1), so as to delimit the blown-air flow area (11).
