The invention comprises a peelable membrane for resealably closing a metal end comprising an outer layer, a tacky layer, and a heat seal layer. The heat seal layer is permanently sealed to the metal end to cover at least one opening in the metal end. The tacky layer causes the peelable membrane to be resealable onto the metal end.

The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.

An abnormal-vibration-predicting method for a roll grinder that grinds an outer peripheral surface of a rolling roll with a grinding wheel while the rolling roll rotates includes an acquisition step and a prediction step. The acquisition step acquires a rigidity parameter related to a rigidity of the roll grinder and a wheel rotation parameter related to a rotational speed of the grinding wheel. The prediction step predicts an occurrence of an abnormal vibration in a process of grinding the rolling roll by using the rigidity parameter and the wheel rotation parameter.
