Claim 0:
1. A rolling mill comprising:
a first work stand defining a first roll gap;
a second work stand downstream from the first work stand and comprising an upper work roll, a lower work roll, and a roll tilt actuator, wherein the upper work roll and the lower work roll define a second roll gap, wherein the first work stand and the second work stand are adapted to receive a metal substrate moving along a pass line, and wherein the roll tilt actuator is configured to control an inclination of at least one of the upper work roll or the lower work roll relative to the pass line;
a strip sensor at an interstand location along the pass line between the first work stand and the second work stand, wherein the strip sensor is configured to measure a parameter of the metal substrate at the interstand location; and
a controller operably coupled to the roll tilt actuator and the strip sensor, wherein the controller is configured to receive sensor data from the strip sensor comprising the measured parameter of the metal substrate, compare the measured parameter to a target parameter, and actuate the roll tilt actuator such that the measured parameter is within a predefined tolerance of the target parameter,
wherein the strip sensor is a strip property sensor, wherein the rolling mill further comprises a position sensor along the pass line between the first work stand and the second work stand, wherein the position sensor is configured to detect a relative location of the metal substrate, and wherein the controller is configured to:
determine a three-dimensional position of the metal substrate based on the measured parameter from the strip property sensor and the detected relative location of the metal substrate from the position sensor; and
actuate the roll tilt actuator such that the determined three-dimensional position is within a predefined tolerance of a target position.
