Real time on-line microstructure analysis using magnetic induction spectroscopy (ROMA)

Lead Research Organisation: University of Manchester
Department Name: Electrical and Electronic Engineering

Abstract

During hot-rolling, the steel industry has no means of determining microstructure development in real-time. Offline analysis of coil-end samples is slow, destructive and does not allow monitoring and control of material properties throughout a production run. Research at the University of Manchester has resulted in the development of a new non-contact system (ROMA), exploiting a novel multi-frequency electromagnetic technique to monitor material microstructure during forced cooling. An important benefit is that it can measure from 0-100% transformation. This collaboration will transfer knowledge to Siemens and enable commercial exploitation by reference-site installation on the Tata Steel hot-strip mill at Port Talbot.

Description This project has help to demonstrate that the sensor technology can operate in a harsh industrial environment on the hot strip mill in a format that can be manufactured by Primetals Technologies Ltd
Exploitation Route A new micro structure monitoring system, trademarked as "EMspec" is available to the steel industry. EMspec targets the production of advanced high strength strip steels. This kind of steel can be difficult for manufacturers to produce reliably owing to the lack of on-line microstructural information, but it is vital to the car industry for reducing vehicle weight. Crucially, EMspec technology has recently been deployed on Tata steel IJmuiden hot strip mill, which is now a reference site for the roll-out of the technology globally.
Sectors Manufacturing, including Industrial Biotechology

 
Description The aim of this project was to prove the feasibility of new microstructure monitoring sensor using multi-frequency excitation for operation on-line on a full scale steel production process. Prior to this project, the steel industry has no direct means of determining microstructure development in real-time. Transformation had to be inferred from thermodynamic models and from temperature measurement from optical pyrometers and confirmed by off-line tests on samples. Off-line analysis of coil-end samples is slow, destructive and does not allow monitoring and control of material properties throughout a production run. This project demonstrated the efficacy of the sensing technology on-line for the first time. This gave the steel industry the confidence to invest in further development of the technology, via a series of industry, EPSRC and EU projects. The resulting EMspec technology is now licensed Primetals Technologies and offered as a commercial product with deployment at the Tata Steel IJmuiden plant as the first reference site. Over 10 million tons of hot steel production has passed over this sensor since.
