Resumo
The EMSpec sensor employs the principle of measuring the complex impedance of the target steel over a range of frequencies these impedance values in turn varies with transformation fraction of the steel. A full scale implementation of the Real Time Transformation Monitoring has been installed at a quality large European steel producer to show the benefits of such a system. A total of three EMSpec sensor heads have been installed between the exit Finishing Mill and the Down Coiler on a HSM. For the successful production of Dual Phase, TRIP and TWIP steels increased control of the cooling regime is demanded; the use of surface temperature measurements alone cannot guarantee to achieve the desired mechanical properties. The EMSpec sensor, which is engineered to withstand this harsh environment, in real time directly measures the percentage transformation of the steel in the cooling area, typically in the accelerated water cooling zone. Using the information from the sensors integrated into the mill model enhances the models ability to predict the transformation profile.
