Systems and methods for using full-width hot sprays to pre-heat rolling mills prior to processing of metal sheet or plate are described herein. The hot sprays may be individually controlled. Using hot sprays can allow the rolling mill to reach operating temperature and achieve a desired thermal crown so that metal sheet or plate may be processed immediately within tolerances for flatness and gauge accuracy. Pre-heating of rolling mills can eliminate the need of the rolling mill to operate in a transitional period of work roll heating and can increase efficiency by eliminating or reducing scrap material and mill downtime. Hot sprays may also be incorporated with existing coolant systems to provide thermal control systems for rolling mills with bi-directional temperature controls.

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.

A method and device for cooling a preliminary strip of metal in a hot rolling mill including work rolls by spraying a cooling agent on to the preliminary strip, screening the preliminary strip in an edge area of the strip from influence of the cooling agent, and deflecting the cooling agent in the area of the strip edges of the preliminary strip, wherein the cooling agent is deflected from the strip edges in an area of an inlet guide of a work a work roll.

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.

The present application relates to a stand base (10) for two or more stands (14) of a rolling mill arranged one behind the other in a rolling direction (W) of a material to be rolled, the stand base (10) comprising two or more receiving modules (12) arranged one behind the other, which are fastened to a common lower base frame (32) and a common upper cover frame (34).

A cold rolling line, a steel sheet production line, a cold rolling method, and a steel sheet production method can suppress work roll deformation and brittle cracking during rolling. The cold rolling line includes one or more cold mills configured to inject coolant towards a work roll and a metal steel strip and to cold roll the metal steel strip, rollers provided upstream from the one or more cold mills in a conveyance direction of the metal steel strip and used to convey the metal steel strip, and a control unit that controls a height difference of the rollers. The control unit controls the rollers so that the metal steel strip is at a lower position towards a downstream side in the conveyance direction at an upstream side of at least a portion of the one or more cold mills including a most upstream mill provided farthest upstream.
