Individually controllable water sprays form a strip cooling zone at a runout table between the last stand of a hot strip finishing train and a coiler. The times required for successive sections of the strip to traverse the runout table (designated residence times) are calculated from a predetermined strip velocity-time profile. Using the residence times, the finishing train temperature, and the desired coiling temperature, spray patterns of varying lengths are calculated for successive sections. The spray patterns are changed to coincide with the movement of the sections across the runout table. |
