Abstract
A steel strip processing system is provided that includes a plurality of microstructure sensors that measure the phase fraction in a steel strip at desired locations in a processing furnace. A process control system includes a plurality of control loops for receiving the outputs of the microstructure sensors to determine the amount of heating and cooling required to achieve a desired phase fraction at the desired locations in the processing furnace. One or more energy systems that receive the output of the process control system to coordinate the heating or cooling of the desired locations to achieve the desired phase fraction.
