摘要： During rolling with a rolling mill, which includes a sheet shape altering device capable of altering a mechanical sheet crown, while the sheet shape altering device is operated correspondingly with a target mechanical sheet crown set value during the dimensional alteration in rolling, the invention enables a stable sheet shape to be achieved, even when the mechanical sheet crown is altered to a large extent during rolling. Specifically, the target mechanical sheet crown set value, during the dimensional alteration in rolling, is previously set based on target mechanical sheet crown set values, before and after the dimensional alteration, prior to start of the dimensional alteration in rolling. The sheet shape altering device is then operated so that an actual mechanical sheet crown, during the dimensional alteration in rolling, is equal to the target mechanical sheet crown set value during the dimensional alteration in rolling.

摘要： A flatness control apparatus for controlling the flatness of a strip in a hot rolling mill, wherein a strip width meter measures center line error values of the strip. The center line error values are the offsets of the center of the strip from the center of the hot rolling mill line and are positive if the center of the strip is offset toward a drive side of the mill. A flatness meter, installed on the delivery side of the mill, measures flatness of the strip at positions specified by the flatness control apparatus. Based on the center line error values and the flatness measurements, the flatness control apparatus calculates adjustments to be made to a work roll bending apparatus on a final stand in the mill in order to control strip flatness.

摘要： The present invention provides an apparatus for measuring flatness of a hot rolled strip based on a contact load of the hot rolled strip to split rolls of a looper in the hot rolling process. The split rolls are assembled in a bracket such that each split roll can be separated from the bracket. A normal-movement control unit for moving the split rolls in the normal direction, and a tangent-movement control unit for moving the split rolls in the tangent direction are porvided at a side of the bracket bearing the split rolls. An impact absorption unit is mounted at a support that is movably connected to the tangent-movement control unit. A pre-pressure application unit is provided at the support to prevent a sensor cap and a load sensor from being released. A heat-shielding ring surrounds the load sensor to prevent the load sensor from being overheated.

摘要： The invention relates to a hot rolling mill, with at least one flatness measuring roller, pertaining to at least one rolling bed, arranged before and/or after one of the stands, which influences the settings of at least one of the stands. The aim of the invention is to improve the arrangement of the roller bed working rollers and the flatness measuring roller, such that the flatness measuring roller may be, optionally, either brought into operation, or be withdrawn into a protected position, whereby, in this case, the gap in the rolling bed thus formed can be closed. Said aim is achieved, whereby the flatness measuring roller may be stored, away from its working position, behind a screen and that the rolling bed is completed with at least one retractable working roller.

摘要： A method for controlling flatness of a strip (1) of rolled material rolled to a first flatness target and coiled and that is subsequently uncoiled, and a system which employs the method. Measurements of the flatness of the strip (1) during rolling are compared to both the first flatness target and to a second flatness target, a Mill Flatness Target 2. A flatness target for each of one or more subsequent processes, a Post Rolling Flatness Target (PRFT) and a measured flatness error is used to adapt a control signal for a mill stand (5) to control and regulate the flatness of subsequent production of rolled material of the same specification. The adaption may be made using different statistical techniques including fuzzy logic and neuro-fuzzy logic control methods. In the preferred embodiment, flatness measurements after decoiling are also fed forward to at least one subsequent process 12 and used to adapt control signals to regulate flatness of the current strip in the subsequent process 12. The advantages include that the rolled strip is more flat after decoiling, and that flatness control over the strip in a subsequent process is more accurate.
