摘要： A rolling mill with oil-cooled top and bottom work rolls at the entry side and a water spray header at the exit side of the bottom work roll. Water cooling is used below the pass line, reducing the heat in the mill substantially without the risk of generating drip-related surface defects during rolling. Water cooling can be used on the bottom work roll and a portion of the oil no longer needed to cool the bottom work roll can be diverted to the top work roll. In some cases, the coolant portion of the flatness control can be operated solely through water-cooling the bottom roll.
摘要翻译：在入口侧具有油冷的顶部和底部工作辊的轧机和在底部工作辊的出口侧的喷水头。在通过线下方使用水冷却，基本上减少了研磨机中的热量，而没有在轧制过程中产生滴流相关表面缺陷的风险。可以在底部工作辊上使用水冷却，并且不再需要一部分冷却底部工作辊的油可以转移到顶部工作辊。在一些情况下，平面度控制器的冷却剂部分可以仅通过对底辊进行水冷却来操作。

摘要： A method of steering a moving metal strip by positioning one or more magnetic rotors near a metal strip. Each rotor includes one or more permanent magnets and rotates to impart a changing magnetic field on the metal strip passing nearby. The magnetic rotors can rotate around an axis of rotation that is parallel to the longitudinal direction of travel of the metal strip. The magnetic rotors can be positioned to impart forces on the strip in any combination of laterally, vertically, or longitudinally. A control mechanism can control the rotor speed, rotor direction, vertical position of the rotors, vertical spacing between rotors, and/or lateral position of the rotors. In some cases, the control mechanism can be coupled to sensors, such as a light curtain and a laser distance sensor, in order to provide closed loop feedback control of a metal strip passing through the non-contact magnetic rotor steering device.

摘要： Control of self-excited third octave vibration in a metal rolling mill can be achieved by adjusting the tension of the metal strip as it enters a stand. Self-excited third octave vibration can be detected and/or measured by one or more sensors. A high-speed tension adjustor can rapidly adjust the entry tension of the metal strip (e.g., as the metal strip enters a mill stand) to compensate for the detected self-excited third octave vibration. High-speed tension adjustors can include any combination of hydraulic or piezoelectric actuators coupled to the center roll of a bridle roll to rapidly raise or lower the roll and thus induce rapid tension adjustments in the strip. Other high-speed tension adjustors can be used.
