Title: Automatic control method for plate thickness on rolling mill
Inventor: TSUZUKI SATOSHI
IPC: B21B37/18
Filed: 1985-09-27
Abstract: PURPOSE:To improve an accuracy of a plate thickness by giving an initial gain of adequate value and measuring on-gauge factor of that time, then giving minute change to the gain in an arbitrary direction to repeat measuring the on-gauge factor. CONSTITUTION:At first, the initial gain Go of adequate value is set by a table system classified with a plate thickness or rolling reduction, etc. and the on- gauge factor is obtained on an arbitrary plate length. In this case, the on-gauge factor is calculated by a specific equation after obtaining the plate length that the deviation of the plate thickness exists within a target deviation. Next, this on-gauge factor OG is discriminated whether it is over the target value OGM or not, and if it is positive, the gain G at that time is used and if not, aminute change is given to the gain G to perform measuring the on-gauge factor OG. The gain change and on-gauge factor measurement are repeated until the no-gauge factor OG exceeds the target value OGM. In this way, the accuracy of plate thickness is improved.
