Abstract

PURPOSE: To make constant the rolling load, and to make beautiful the product shape, by calculating the thickness of the sheet under the rolling work with the purpose of finding its deviation from the aim thickness, and by controlling the speed ratio of reducing rolls depending on above obtained thickness deviation.
CONSTITUTION: The roll gap of reducing rolls R1, R2, under the no-load condition is detected by the roll position detector 1; on the other hand, the rolling load is detected by the rolling load detector 2 like as the load cell, etc. The thickness of the rolled material 4 is detected by the gaugemeter 5, and the deviation from the reference data is integrated by the monitoring circuit 6 whose integration output is inputted to the thickness controller 7. The thickness controller 7 is inputted with the output of the roll position detector 1, the output of the rolling load detector 2, the output of the monitoring circuit 6, and the reference data signal h1 of the thickness reference setter 3. The output of the thickness controller 7 is given to the speed controllers 8, 9, in order to control the speed of driving motors M1, M2, or reducing rolls R1, R2, so as to equalize the thickness of the sheet to the aim thickness.
