Definitions
- the present invention relates to a running thickness changing method for changing a setting from a preceding material to a succeeding material when a rolled material is continuously rolled by a cold tandem rolling mill, and in particular, to a method for changing a running thickness at a point where a running thickness changes.
- FIG. 2 is a block diagram showing a state in which the tip end portion of the muff opening is controlled in accordance with the present invention.
- 10 is the preceding material
- 24 i-1 is the thickness gauge on the i-th stand entry side
- 22 1 is the tensiometer on the i-th stand entry side
- 20 i + 1 is a load meter of the (i + 1) th stand and the (i + 2) th stand
- 2 2 i + 1 is a tension meter on the exit side of the (i + 1) th stand.
- the exit thickness deviation of the 1st and 3rd stands when the run was changed by the conventional method of changing the running thickness without the running variation correction calculation based on the actual rolling performance (called the conventional method).
- Fig. 4 shows the change in the thickness variation on the exit side of the third stand because there is no thickness gauge, and the running variation after the next stand is corrected using the rolling results as in the previous application.
- FIG. 5 shows a case where the roll speed correction of the formula was not performed (referred to as a comparative method)
- FIG. 6 shows a case where a run change was performed by the method of the present invention.
- the sheet thickness deviation generated at the first stand remains in the third stand at the subsequent stage.
- the thickness deviation at the tip of the coil which occurred in the first stand due to poor running variable setting, was corrected in the second stand, the AGC in the first stand was turned on, and the first stand came out.
- the thickness deviation increases at the third stand as the thickness on the side approaches the target value.
- the thickness of the second stand exit side is controlled by the equation (2). Therefore, the thickness can be controlled to the target value from the tip of the coil.
