Definitions

  • the length of the tapered plate thickness portion after rolling in the preceding stand is calculated using the plate speed measured between the target stands, the length of the tapered plate thickness portion is divided by the amount of change in the reduction position in the target stand to calculate the change speed of the reduction position, and the roll gap of the target stand is changed by the calculated change speed.
  • the material to be rolled is a high deformation resistance steel plate.
  • a method for changing plate thickness while traveling is provided that can reduce tension fluctuations.
  • FIG. 1 is a schematic diagram showing a cold rolling facility in a first embodiment of the present invention.
  • FIG. 1 is an explanatory diagram showing a conventional method for changing plate thickness while traveling, in which (A) shows a state where the plate thickness changing position S1 is located upstream of the first stand, (B) shows a state where the plate thickness changing position S1 has reached the first stand, (C) shows a state where the joint has reached the first stand, (D) shows a state where the plate thickness changing position S1 has reached the second stand, (E) shows a state where the plate thickness changing position S2 has reached the second stand, and (F) shows a state where the joint has reached the second stand.
  • Fig. 1 is a schematic diagram showing an example of a continuous cold rolling facility 1 according to the first embodiment of the present invention. Note that Fig. 1 does not show other devices associated with the facility (e.g., an unwinder, a welder, and a looper on the entry side, and a cutter, a winder, and other devices on the exit side).
  • devices associated with the facility e.g., an unwinder, a welder, and a looper on the entry side, and a cutter, a winder, and other devices on the exit side).
  • the continuous cold rolling equipment 1 includes a tandem rolling mill 2, multiple plate thickness measuring devices 3, a rolling control controller (PLC) 4 that controls the tandem rolling mill 2, and a control computer (process computer) 5 that manages the continuous cold rolling equipment including the rolling control controller 4.
  • PLC rolling control controller
  • process computer control computer
  • the method for changing the thickness while traveling according to the second embodiment calculates the length L N-1 of the tapered thickness portion after rolling in the preceding stand using the plate speed measured between the target stands, calculates the change speed R N of the reduction position by dividing the length L N-1 of the tapered thickness portion by the change amount of the reduction position in the target stand, and changes the roll gap of the target stand at the calculated change speed R N.
