Abstract
PURPOSE: To easily peel scale from a steel plate by forcing the plate after hot rolling to be cooled in a specified temp. range at a predetermined rate without passing through a naturally cooling process.
CONSTITUTION: A steel plate 3 is coiled at 1 immediately after hot rolling, uncoiled, and fed to a cooling device 4 at ≥400°C. In the apparatus 4 the plate 3 is cooled to ≤300°C at 3W2,000°C/sec cooling rate with air or water sprayed from many nozzles 5. The cooled plate 3 receives a bending strain through a scale breaking device 7, and it is fed to a descaling chamber 8, where scale on the plate 3 is removed by mechanical shot blasting.
