Abstract

1397136 Cooling rolled strip CENTRO SPERIMENTALE METALLURGICO SpA 13 July 1972 [17 July 1971 22 June 1972] 32752/72 Heading B3M A cooling box, for directing water on to a hot-rolled strip between the final stand of a mill and a coiler, provides a film of water from a transversely disposed slit having convex side walls. The film has low turbulence and may be adjustable in flow rate and direction. Similar boxes may be positioned both above and below a strip being cooled. In one form, Fig. 3, the box has lower slits 11 defined between shaped walls 10 and a vertically adjustable profiled blade 12. In place of the single blade, a number of blades may be provided along the length of the box, or several boxes may be provided transversely of the strip. In an alternative form, Fig. 8, the box has curved side walls 30 which define the shape of the water film, the walls being rotatably or laterally adjustable. In a further embodiment, Fig. 9, the water film passes between shaped walls 33 and a central blade 35 to an outlet slit 34.
