PROPERTYMONINLINE MEASUREMENT OF STEEL STRIPPROPERTIESWith increasing quality requirements,
higher productivity, increased
competition and cost pressure, process
measurement and control is more
important than ever. Good processcontrol is essential to stable andconsistent production, particularly
for higher strength grades that are
more process critical. End users
also require greater levels of quality
documentation and certification.
YOUR CHALLENGE
Tensile testing only provides values
at the sample position, so it is notpossible to get a quality assessment
for full strip length. Tensile tests arealso slow and provide no immediate
feedback to the process. Conventionallymore comprehensive monitoring has
been achieved by recording processparameters and modelling simulation.
Measurements directly related to themicrostructure are preferable. The
challenge is taking direct measurements
without destructive testing.

OUR SOLUTION
PropertyMon provides in-line detectionof mechanical or magnetic properties inthe steel strip using an electromagnetic
principle. The system performs a
continuous, in-line and contactless
inspection along the strip length. The
results are immediately available,visualized for the benefit of theoperator and stored in PropertyMons’internal database. Non-contact sensor
heads inspect the entire strip at fullplant speed. The sensors can be
automatically moved to measure atdifferent positions. Both longitudinal
and transverse measurements
are possible. The compact sensor
geometry means that the measurement
is independent of strip speed.
All hot- and cold-rolled ferromagnetic
steel grades including micro-alloyed,
IF, dual-phase, silicon and TRIP steel
grades can be measured.

LONGITUDINAL& TRANSVERSE
MEASUREMENTFUNCTION
The PropertyMon system measures electromagnetic values(hysteresis curve) of ferromagnetic materials and exploits theinterrelationship between mechanical, material and magnetic
properties. Output values with an accuracy in the same range
as laboratory destructive tests are calculated by applying
multiple linear regression. The calibration is obtained from
PropertyMon measurements and corresponding laboratory
samples, the use of online process parameters from the plantis not necessary but can be used to enhance the results.
The system is directly connected to the Level 1/2 automation
system of the processing line so that all relevant information,such as strip identification, grade, thickness, strip position,etc., can be obtained and the results sent back and stored
in the PropertyMon database with synchronization to themeasurement position.
MAIN FEATURES• Simultaneous detection of mechanical and magnetic
properties• Reliable differentiation between different steel grades• Directional measurements for anisotropic properties

PropertyMon sensors

SUMMARY
The PropertyMon in-line system provides non-destructive
assessment of the product properties along the entire lengthof the strip. Calibration with conventional destructive test
data, provides comprehensive and reliable quality assurance
along the full strip length. This enables the consistency andstability of production to be monitored and any deviationin process and properties to be quickly identified so that
remedial action can be taken.

• Compact industrial sensor heads provide localizedmeasurements independently of strip speed• Tracking of sensor stand-off height from strip to ensure
accuracy of results• Sensor traversing function for measurement at different
transverse positions• Automatic or manual operation and control from local
cabinet, remote access from operator pulpit also possible• 4-Step safety features to avoid strip contact and ensure
operational safety
