Original Kurzfassung:
Focus on quality control in the steel industry in recent
years has shifted to inline non-destructive testing (NDT) in order
to detect defects at the earliest possible stage in the production
process. Using highly sensitive sensors based on the giant
magneto resistive effect (GMR), it is possible to detect the
magnetic flux leakage caused by a defect near the surface of a
steel strip. The detection and elimination of such defects is vital
to sustaining product quality and reducing costs.
The R&D activities dedicated to the innovative process model
currently being developed by voestalpine Stahl GmbH have been
divided into three phases. Phase 1 (basic research mechatronics)
was spent investigating a variety of defect detection methods and
subsequently discussing and evaluating the sensitivity and speed
required for inline inspection. Phase 2 (applied mechatronics)
included the construction of a prototype and test measurements
that produced the promising results presented in this paper.
Based on the results of the preliminary tests and simulations of
the magnetic field, a second prototype is now being built for
offline measurement and further development of the sensor
design. In the event that this second prototype is successful, an
inline configuration will be implemented in Phase 3 (integrated
mechatronics).
