<p>PURPOSE:To improve the accuracy of a sheet thickness on an outlet side by setting a rolling mill to the draft position determined by using a specific gage meter equation and executing rolling then calculating and adjusting the draft position by the gage meter equation from the changing roll profile. CONSTITUTION:Predicted rolling load 1, the sheet thickness 2 on the inlet side, the roll profile 3 and the sheet thickness 4 on the outlet side are taken in as rolling data and the draft position 6 is calculated by using the prescribed gage meter equation 5. The draft position 8 of the rolling mill 7 is thereby set and the rolling is executed. The actual rolling load 9, the actual draft position 8 and the changing roll profile 10 are actually measured or the roll profile 10 is taken in as the data predicted by a prediction equation upon ending of the rolling. The sheet thickness 11 on the outlet side is then calculated by the prescribed gage meter equation 5 and the information on the sheet thickness on the inlet side of the next pass is thus obtd. The deterioration of the accuracy by the change of the roll profile is thus obviated and always the good accuracy of the sheet thickness is obtd.</p> |
