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

摘要

A steel strip processing system is provided with a plurality of microstructured sensors for measuring the phase fraction within the steel strip at desired locations in the processing furnace.The process control system comprises a plurality of control loops for receiving the output of the microstructured sensor and determining the amount of heating and cooling required to achieve the desired phase fraction in the desired arrangement within the processing furnace.At one or more energy systems, the output of the process control system is received to adjust the desired location heating or cooling to achieve a desired phase fraction.
