<p>PURPOSE: To improve thickness accuracy in the head part by comparing the signal from a thickness detector on the outlet side of a finishing mill with gage-meter thickness at the final stand, correcting the gage-meter thickness by the difference and controlling a roll gap. CONSTITUTION: The roll gap is controlled with a roll gap controlling mechanism 2 so as to become the roll gap that is calculated with a computing element 5. The signals from a load detector 3 and thickness detector 4 on the outlet side are inputted to the computing element 5, calculated as the monitor amounts for the gage-meter thickness calculation and thickness detector 4 on the outlet side and the roll gap is also adjusted through the roll gap controlling mechanism 2. In this way, the gage-meter thickness is more accurately calculated and the thickness accuracy is improved over the entire length of the rolled stock.</p> |
