摘要： Mill spring constant change signals are produced after each of a series of screwdown regulation cycles where each change signal is produced as a function of the ratio of the gauge deviation remaining after the regulation cycle, to the change in rolling force which occurred during the regulation cycle. The series of ratio change signals are then averaged to produce a mill spring constant correction signal which is used to correct the previously established mill spring constant. The corrected mill spring constant is then used to generate a new screwdown reference signal for the next series of regulation cycles. Provision is made to limit check and average gauge deviation so that the mill spring corrections are only made when certain predetermined gauge deviation limits are exceeded.
