Definitions

  • 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).
  • Patent Literature 1 Japanese Patent Application Laid-open No. 2012-110939
  • 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.
  • FIG. 3 is a diagram illustrating the breakage rates of Conventional Example and Invention Examples.
  • 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.
