摘要： A hot rolling mill (15) and method for operating the hot rolling mill where the shape of a rolled strip (12) is controlled by localized cooling devices (71A, 72A, 71B, 72B) positioned at intervals along work rolls in at least three lateral zones, a central and two edge zones, and capable of separately cooling each zone to control the shape of the work rolls (16A, 16B) in that zone and inhibit the formation of shape defects occurring in the strip (12) being rolled. Five zones may be provided across the work surface of the work rolls (16A, 16B) so that two intermediate zones can control for quarter buckles. The hot rolling mill has particular application in continuously casting thin strip. The method can be made automatic by sensing downstream of the hot mill the shape of the strip in each zone.

摘要： Apparatus and method of controlling strip geometry in a casting plant having a rolling mill. A target thickness profile is calculated as a function of the measured entry thickness profile of the strip while satisfying profile and flatness operating requirements. A differential strain feedback from longitudinal strain in the strip is calculated by a control system by comparing the exit thickness profile with the target thickness profile, and a control signal is generated to control a device capable of affecting the geometry of the strip processed by the hot rolling mill. A feed-forward control reference and/or sensitivity vector may also be calculated as a function of the target thickness profile, and used in generating the control signal sent to the control device. The control device may be selected from one or more of the group consisting of a bending controller, gap controller and coolant controller.

摘要： Pinch roll apparatus comprises upper and lower pinch rolls (60A, 60B) each having a diameter between 300-1500mm positioned laterally adjacent each other to form a nip between them through which metal strip (12) can be continuously fed and a rotational drive capable of counter rotating the pinch rolls (60A, 60B) to cause the strip to pass through the nip between them. The axes of pinch rolls (60A, 60B) are offset in the direction of travel of the strip through the pinch rolls with the upper pinch roll offset positioned downstream of the direction of travel of the strip, and a tilt drive is capable of tilting the upper pinch roll (60A) by a tilt angle, measured at the edge of the strip, relative to the lower pinch roll to control steering of the strip, such that (R upper min + h min + R lower min - |Tilt os-ds |)/(R upper max + h max + R lower max )>cos(θ).
摘要翻译：夹送辊装置包括上和下夹送辊（60A，60B），每个具有直径在300-1500mm之间，彼此横向相邻地定位，以在它们之间形成辊隙，通过该辊隙可以连续地供给金属带（12），并且能够反向旋转夹送辊（60A，60B）以使带材通过它们之间的辊隙。夹送辊（60A，60B）的轴线在带材穿过夹送辊的行进方向上偏移，上部夹送辊偏移位于条带的行进方向的下游，并且倾斜驱动器能够倾斜上部夹送辊（60A）相对于下部夹送辊在带的边缘处测量的倾斜角度以控制条带的转向，使得（R上限+ h min + R较低min - |倾斜os- cos（¸）/（R max max + h max + R lower max）> cos（¸）。

The axes of pinch rolls (60A, 60B) are offset in the direction of travel of the strip through the pinch rolls between 10 and 130mm and with the upper pinch roll offset positioned downstream of the direction of travel of the strip. A tilt drive is capable of tilting the upper pinch roll (60A) by a tilt between 0.5 and 5.0mm, measured at the edge of the strip, relative to the lower pinch roll to control steering of the strip.
