摘要： In a tandem type rolling mill, it is difficult to control each roll bending force so as to produce a constant forward slip and a constant backward slip at each stand in the transversal direction.A first shape meter is disposed between a pay-off reel and a first stand and a second shape meter is disposed between a tension reel and a last stand. The roll bending forces under the first stand, the second stand, . . . the lth stand are controlled so as to produce a constant backward slip at the first stand as measured by the shape meter disposed between the pay-off reel and the first stand to provide a predetermined value.The roll bending forces under the first stand, the second stand, . . . the lth stand are also controlled so as to provide a constant forward slip at the last stand as measured by the shape meter disposed between the last stand and the tension reel to provide a predetermined value.The feeding of a roll coolant is also controlled together with the control of roll bending forces.

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： In a method of continuously rolling a metal strip by a tandem mill including a plurality of mill stands, when the strip size is to be varied, pass signals are generated when a given size change point of the strip passes successively through respective mill stands. A computer generates control signals in response to the pass signals and each control signal varies the degree of bending of each roll when the size change point reaches a mill stand.

摘要： A method of and an apparatus for controlling a rolling mill whereby the thickness distribution across the width of a strip steel produced by rolling can be made uniform and a desired flatness can be obtained in the strip steel. A thickness distribution and a length distribution across the width of the strip steel before being rolled are measured, and a thickness distribution desired to be obtained in the strip steel after being rolled is calculated based on the values obtained. At the same time, an expected roll opening distribution corresponding to the roll openings S1 and S2 on the device side and the operation side respectively and the roll bender forces Q1 and Q2 on the drive side and the operation side respectively is calculated based on an expected deflection and an expected flattening of the rolls, into a function of the factors S1, S2, Q1 and Q2, then the desired values of S1, S2, Q1 and Q2 are determined at a time when the dispersion of the difference between the thickness distribution desired to be obtained and the expected roll opening distribution is minimized. Control of the roll screw-down device and the roll bending device is effected by utilizing the desired values of S1, S2, Q1 and Q2 respectively.

摘要： A device for automatic adjustment of thickness of strip being rolled on units producing strip material, comprising a closed hydraulic system providing local enhancement of roll mill stand rigidity within a force range approximately equal to a range of deviations of the rolling pressure from a specified value. The system includes at least one hydraulic power cylinder disposed intermediate of work roll supports, a second hydraulic cylinder functioning as a damper whose piston is being fixed as the strip passes through the roll mill stand, said hydraulic cylinders being arranged symmetrically on both sides of the roll mill stand, and a controlled valve. The device comprises also a second closed hydraulic system providing local enhancement of roll mill stand rigidity within a force range sufficient to correct the deviations in the strip thickness from that specified. The second system includes at least one hydraulic power cylinder disposed intermediate of backup roll supports, a second hydraulic cylinder functioning as a damper whose piston is being fixed as the strip passes symmetrically the roll mill stand, said hydraulic cylinders being arranged symmetriclaly on both sides of the roll mill stand, and a controlled valve. In addition, the device is fitted with a circuit for stabilizing the thrust of the work rolls within a specified range and with a circuit for correcting deviations in the transverse profile of the strip being rolled from that specified. The latter circuit has a gauge for measuring the pressure within the second hydraulic system, a setter of the rated thrust force of the back up rolls and an adder connected with one input to the output of the gauge for measuring pressure within the first hydraulic system and with the second input to the output of the pressure gauge of the second hydraulic system, its third input being connected to the rated thrust force setter of the work rolls and a fourth input - to the rated thrust force setter of the backup rolls with its output being connected through a variable gain amplifier to the input of a comparison element and through another amplifier also with a variable gain to the input of an initial pressure setting controller of the first hydraulic system.

摘要： A plate crown control device controls tandem rolling equipment based on delivery-side plate crown setting calculation values of stands calculated by setting calculation, mechanical plate crown setting calculation values of the stands, and setting values of bending forces and shift positions of the stands. A processor calculates first learning current values based on differences between mechanical plate crown observation values and mechanical plate crown actual calculation values. The processor prorates first learning values with first learning current values and smoothing gains and updates the first learning values. The processor calculates, in the setting calculation for the next and subsequent materials, setting values of bending forces and shift positions of the stands using mechanical plate crown setting calculation values after correction obtained by adding the first learning values to the mechanical plate crown setting calculation values.

摘要： A multistage rolling mill 100 includes support bearings 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h arranged on the entry side and/or the exit side of work rolls 2a and 2b, and supporting the work rolls 2a and 2b on an work side and a drive side. The offset positions in a pass direction of the pair of work rolls 2a and 2b for rolling a strip 1 are changed by moving in and out the support bearings 10a, 10b, 10c, 10d, 10e, 10f, 10g, and 10h to the entry side or the exit side with respect to the pass direction. A multistage rolling mill capable of rolling a hard material efficiently and suitable for obtaining a strip of high product quality is thereby provided.
