precise product profile. In this way
up to 600 profiles can be generated
every minute. This allows manufac-
turers to significantly reduce scrap
while maintaining stricter toler-
ances of ½ and ¼ DIN.
There are no longer any restrictions
as to the shapes the system can
cope with. The STEELMASTER SMR
models can handle any asymmetri-
cal, polygonal and irregular shapes
made of steel and metal up to a
diameter of approximately 135 mm
and temperatures of up to 12000 C.
The innovative rotary movement
isn’t the only technical refinement,
because there is also the unique,
non-contact transmission of power
and signals within the measure-
ment unit. The STEELMASTER SMR
software is very flexible, allow-
ing data statistics, numerical and
graphical displays, logs and so on
to be freely configured in line with
requirements and working practice
in the production environment.
ZUMBACH developed a novel meth-
od, EPM (Enhanced Profile Measure-
ment, pat. pend.) for geometries
with irregular or asymmetric shape
aberrations (e.g. asymmetric over-
fill or underfill). In particular it is
also able to capture and calculate
polygonal shapes, which can occur
in certain rolling processes or af-
ter subsequent peeling / grinding
operations. For any shape it will
measure at high accuracy not only
min., max. and mean diameters but
also the true out-of-round deviation
RONt as defined by ISO / TS 12181-1
as well as the inscribed circle MICI
and the circumscribed circle MCCI.
An optional module named FPS, es-
pecially for 3-roll blocks, calculates
accurate values corresponding to
the diameter values which would
be found by manual 3-point mi-
crometer screws (if both readings
are related to room temperature).
This FPS module additionally cal-
culates the “Touch” and “Gap” di-
ameters which are essential for the
initial roll setting.
The dynamic regression analysis
included in the software package
means that twist and angle of twist
no longer influence the measure-
ment result. This results in lower
scrap rates and ensures compliance
with strict tolerances. The technol-
ogy also performs regardless of po-
sition, vibration, material tempera-
ture and light intensity.
STEELMASTER SMR measuring units
have the same tried-and-tested ar-
chitecture as the proven static and
oscillating systems. ZUMBACH de-
livers 100% quality inspection with
virtually 0% outlay for repairs and
maintenance. The fully contact-free
transmission of power and signals
also ensures maximum operating
safety. An efficient air flushing
and cooling system keeps the unit
functioning reliably and can be sup-
plemented if necessary by a water
circuit.
All STEELMASTER systems can be
extended to include up to four
measuring units with a single data
acquisition and processing system.
Any combination of static, oscillat-
ing and rotating SMR measurement
units may be used.
By opting for the STEELMASTER
measuring system, manufacturers
can benefit from high-precision
measurements and the resulting
competitive advantages, such as
faster start-up, less downtime and
lower personnel requirements. This
results in new quality standards
and opens up new, multiple appli-
cations.
Applications:
Hot and cold rolled products:
• Wire
