Abstract
There is a quantitative relationship between the mechanical properties of steel and impedance signals. However, there is a lack of effective online monitoring and characterised methods for steel microstructures and mechanical properties, leading to issues such as low qualification rate of steel quality and high alloy costs (to ensure mechanical strength). In order to control steel production from the perspective of steel microstructures, advanced detection methods and measurement instruments are necessary for online monitoring of the production process. In this study, by investigating the electromagnetic response of steel, an online electromagnetic non-destructive characterisation system is established. The relationships between impedance, ferrite phase fraction and mechanical properties were established, showing that for steel, the ultimate tensile strength (UTS) increased by 25 MPa, yield stress by 36 MPa and impedance by 0.0016 Ω, while for HRB400E, UTS increased by 22 MPa, yield strength by 17 MPa and impedance by 0.006 Ω. Therefore, it is possible to monitor the microstructure and mechanical properties of steel production in real time using the electromagnetic non-signals.
