Method and system for controlling steel strip microstructure in heat treatment equipment using electromagnetic sensors

摘要

A steel strip treatment system is provided, the steel strip treatment system comprising a plurality of microstructure sensors for measuring the phase fraction of the steel strip at desired locations of the treatment furnace. The 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 desired locations of the processing furnace. One or more energy systems receive the output of the process control system to coordinate heating or cooling of desired locations to achieve the desired phase fraction.
