Abstract
Simultaneous control of thickness and profile of rolled metal strip leaving a rolling mill is ensured by measuring the force excerted on the clamping screws and bending force exerted on the rollers. The position of the clamping screws is observed and the date is fed into a computer. the measured value of the force exerted on the clamping screws is compared with a reference value, stored in the memory of the calculator and determined as a function of the required initial thickness and of the initial profile of the strip. If these are not equal, the computer determines the amounts with which the position of the screws and the bending force exerted on the rollers must vary from the initially determined values to obtain a certain initial thickness and profile. Based on results during the calculation, the variations of the clamping screws positions and of the bending force exerted on the rollers, the computer gives corresponding instructions so that the values of the initial thickness and of the initial profile of the strip equal the previously determined instruction vaues.
