Sensor Technology

Background:

Continuous annealing is crucial for advanced high-strength steels, requiring precise control of mechanical properties.
Monitoring microstructural evolution in real-time during annealing is challenging due to harsh industrial conditions (high temperature, speed, limited space).

Purpose of the Study:

To develop and validate a multifrequency electromagnetic sensor system for real-time, in-situ monitoring of steel microstructural transformations during thermal cycling in continuous annealing lines.

Main Methods:

Experiments were conducted on austenitic stainless steel, pure nickel, and ferritic stainless steel to assess sensor response to changes in resistivity and magnetic permeability.
A finite element modeling study was performed to analyze the effect of frequency and permeability on sensor response.

Main Results:

The multifrequency electromagnetic sensor system demonstrated a strong response to variations in material resistivity and magnetic permeability.
Complementary data across different frequencies provided comprehensive insights into microstructural changes.
The system successfully monitored ferromagnetic-to-paramagnetic transitions in nickel and ferritic stainless steel.

Conclusions:

The developed electromagnetic sensor system shows significant potential for characterizing thermally induced changes in steels non-destructively.
This technology establishes proof of concept for high-temperature electromagnetic sensing in steel processing.
The findings lay the groundwork for industrial deployment in monitoring phase and recrystallization transformations.
