Definitions

  • the present invention relates to a method for shape control in a rolling mill and a device for shape control in the rolling mill, see e.g. JP 2017 064790 A , which forms the basis for the preamble of claim 1 and claim 2.
  • a method is employed in which the shape of a steel sheet is measured after rolling, and then the result of the measurement is fed back to a rolling mill to control the shape of the steel sheet to within an allowable range. Furthermore, another method is employed in which a sheet thickness gauge or both a sheet thickness gauge and a sheet passing speedometer are provided in each of rolling stands to perform roll gap control or roll speed control in each of the rolling stands (see Patent Literature 1).
  • the above-described methods are for controlling the thickness of a steel sheet to within an allowable range, and therefore effective in reducing sheet thickness defects, but are not effective in preventing sheet breakage.
  • a steel sheet has a width of 1200 mm or wider, such wide steel sheet is prone to cause breakage more easily due to a shape defect.
  • the present invention is proposed in view of the above-described problem, and an object of the present invention is to provide a method for shape control in a rolling mill and a device for shape control in the rolling mill, the method and the device being capable of substantially preventing the breakage of even a wide steel sheet without increasing the cost of, for example, equipment modifications.
  • a method for shape control in a rolling mill includes: a measurement step of measuring a shape of a steel sheet on a delivery side of the rolling mill; and a control step of controlling the rolling mill in a manner that the shape of the steel sheet falls within an allowable range, based on the shape of the steel sheet measured at the measurement step, wherein the control step includes a step of setting a control gain smaller than a control gain for a width of a steel sheet as a target for rolling being equal to or smaller than the predetermined value when the steel sheet as the target for rolling has a width greater than a predetermined value.
  • a device for shape control in a rolling mill includes: a measurement unit configured to measure a shape of a steel sheet on a delivery side of the rolling mill; and a control unit configured to control the rolling mill in a manner that the shape of the steel sheet falls within an allowable range, based on the shape of the steel sheet measured by the measurement unit, wherein the control unit is configured to set a control gain smaller than a control gain for a width of a steel sheet as a target for rolling being equal to or smaller than the predetermined value when the steel sheet as the target for rolling has a width greater than a predetermined value.
  • a method for shape control in a rolling mill and a device for shape control in the rolling mill according to the present invention can prevent the breakage of even a wide steel sheet without increasing the cost of, for example, equipment modifications.
  • FIGS. 1(a) and 1(b) are a diagram illustrating a target shape and an actual shape of a steel sheet having a sheet width of 1200 mm or smaller and a diagram illustrating a target shape and an actual shape of a steel sheet having a sheet width greater than 1200 mm, respectively.
  • the actual shape of the steel sheet is such that edge portions and a center portion in the width direction of the steel sheet have an elongated shape while intermediate portions (quarter portions) between the edge portions and the center portion have a stretched shape, and the shape of any of these portions is similar to the target shape.
  • the steel sheet having the above-described shape distribution is less likely to break because the edge portions of the steel sheet have the elongated shape.
  • the actual shape of the steel sheet is such that distributions of the elongated shape and the stretched shape in the width direction do not necessarily match those in the target shape (shape irregularity), and such mismatch covers a wide region.
  • an actuator of the rolling mill for adjusting the shape of the region having partial shape irregularity may be overcontrolled. Then, such overcontrol causes shape distortion in another region that is different from the region having shape irregularity, whereby, for example, the edge portions changes in shape in the stretch direction, so that the steel sheet breaks more easily.
  • the control gain of an actuator has conventionally been set to a constant value, regardless of the width of a steel sheet.
  • the control gain indicates an operation amount of the actuator configured to control a shape.
  • the actuator operates to perform shape control.
  • the amount of this operation is defined as control gain.
  • control gain in the case where the width of a steel sheet is greater than a predetermined width, for example, greater than 1200 mm, the use of the same value of the control gain results in overcontrol, which leads to increased shape distortion, so that the risk of breakage of the steel sheet is incurred.
  • the width of a steel sheet that is prone to cause distortion of the shape of the steel sheet is defined beforehand as a predetermined sheet width.
  • the control gain of the actuator configured to control the shape of the steel sheet is made smaller than a control gain for the width of the steel sheet as a target for rolling being the predetermined sheet width or smaller.
  • the control gain is made smaller than a control gain for the width of the steel sheet being 1200 mm or smaller.
  • a continuous cold rolling mill 1 illustrated in FIG. 2 the control of the shape of a steel sheet was exemplarily performed using a result obtained by measuring the shape in the width direction of the steel sheet on the delivery side of a final rolling stand.
  • the continuous cold rolling mill 1 illustrated in FIG. 2 was a rolling mill configured to roll a steel sheet S delivered from a reel 2a by using rolling stands 3a to 3e and then wind the steel sheet S around a reel 2b.
  • a shape measuring device 10 configured to measure a shape in the width direction of the steel sheet S was disposed.
  • a controller 11 Based on the shape in the width direction of the steel sheet S that was measured by the shape measuring device 10, a controller 11 controlled an actuator (for shift control or bender control of a tapered first intermediate roll) provided in each of the rolling stands, and thereby controlled the shape in the width direction of the steel sheet S to within an allowable range.
  • an actuator for shift control or bender control of a tapered first intermediate roll
  • the thickness of the steel sheet S was 0.1 to 3.5 mm and the rolling speed thereof was 30 to 2000 rpm.
  • the width of the steel sheet S was within a range of 600 to 1300 mm. Furthermore, based on past operational performance, the width of the steel sheet S subjected to the change of control gain was set to 1200 mm, which was a limit beyond which the risk of breakage caused by shape distortion increased.
  • a method for shape control in a rolling mill and a device for shape control in the rolling mill can be provided, the method and the device being capable of substantially preventing the breakage of even a wide steel sheet without increasing the cost of, for example, equipment modifications.
