摘要： There is provided hydraulically-operated work roll gap control cylinders forming a closed-circuit hydraulic system during rolling, and there are also provided hydraulically-operated backup roll control cylinders to which is connected a rolled product thickness gauge in order to keep constant the work roll gap depending on the pressure existing in the closed-circuit hydraulic system. The apparatus is provided with a hydraulic volume compensator operating in conjunction with the closed-circuit hydraulic system of work roll gap control and is also provided with a logic module connected to said compensator. The volume of fluid contained in the closed-circuit system changes in response to the corrective signal characteristic of a deviation of the strip thickness from the specified gauge. The passage of the signal to the hydraulic volume compensator is cleared or blocked by a special transportation lag unit.

摘要： There is described a method for controlling the profile of a workpiece on a rolling mill, wherein the workpiece is imparted with a predetermined profile in the roughing stage which is suitable for further control in the following finishing stage. In the finishing stage, the desired profile of the workpiece is attained by controlling the temperature of the workpiece at inlet position of the second finishing stage and/or controlling the thickness of the workpiece at outlet position of the first roughing stage. To determine the temperature and/or the thickness of the workpiece at inlet position of the second finishing stage a crown model formula is utilized. The crown model formula includes some constants, and variables which represent the mean temperature of the workpiece in the second finishing stage, and the thickness of the workpiece at the outlet of the first roughing stage.

摘要： Gage control method and system for tandem rolling mills of the type wherein final output gage is controlled by comparing actual output gage with desired output gage to develop an error signal for controlling the speed of the last stand and, hence, tension in the strip material being rolled between the last two stands. The invention is characterized in that the roll force exerted on the strip by the last stand is maintained constant for all variations in last stand speed, thereby enabling a greater range of strip gage change via the last stand in the tandem mill.
