Referring to FIG. 3, the plate loop may be small, but may be large enough to instantaneously come into contact with a target facility such as a cooling facility due to the large deformation of the material.

Since the moving speed of the plate, which is the material during the hot rolling process, is very fast, when a plate loop occurs and collides with the cooling system, the impact transmitted to the cooling system by the impact of the material is very large.

For this reason, there exists a problem that cooling facilities, such as the injection nozzle provided in a cooling head, break.

2 and 3, a plurality of cooling facilities may be installed along the moving direction of the raw material.

Since a plurality of unit cooling facilities are equipped with many cooling nozzles and a plate width direction cooling water amount adjusting device, when one unit cooling system is damaged, the next plate may not be cooled and may lead to an operation interruption. There is a problem that can be degraded.

However, if the cooling equipment is damaged due to such a problem, there is no solution other than the method of stopping the work and repairing the equipment in the manufacturing process of steel sheet or the like and repairing the damaged equipment at regular repair time. there was.
