摘要

Process for measuring the roll gap in a rolling mill comprises following the focal wear in the central region of the roll surface using one or more sensors to establish the roll wear, the chamfer position of the moving roll and the roll gas change. Preferred Features: The roll gap measurement is carried out using sensors based on the fluidized current principle. A coil is present in the sensor as a component of an electrical oscillating circuit. The sensor is connected via signal lines to a digital display.
