Claim 9:
10. A method comprising:
receiving a metal substrate moving along a pass line in a first roll gap of a first work stand of a rolling mill;
receiving the metal substrate moving along the pass line in a second roll gap of a second work stand of the rolling mill, wherein the second work stand is downstream from the first work stand and comprises an upper work roll, a lower work roll, and a roll tilt actuator, wherein the upper work roll and the lower work roll define the second roll gap, 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;
measuring a parameter of the metal substrate with a strip sensor at an interstand location along the pass line between the first work stand and the second work stand;
comparing the measured parameter to a target parameter; and
actuating the roll tilt actuator such that the measured parameter is within a predefined tolerance of the target parameter,
wherein measuring the parameter comprises measuring a strip property parameter of the metal substrate, and wherein the method further comprises:
detecting a relative location of the metal substrate with a position sensor between the first work stand and the second work stand;
determining a three-dimensional position of the metal substrate based on the measured strip property parameter and the detected relative location of the metal substrate; and
actuating the roll tilt actuator such that the determined three-dimensional position is within a predefined tolerance of a target position.
