PEELING LINES
Quality and productivity in bright steel production
Bright steel
processing lines
Integrated solutions from a single source
The bright steel industry is characterized by ever
stricter quality and productivity requirements.
As the world-wide leading supplier, the product unit
Schumag & Copper of SMS Meer offers both high
performance single units but also, interconnected
systems with a maximum degree of automation.
They are suitable for machining of round bars and
thick walled tubes made of steel and steel alloys.
Especially with the PM-series in diameter rage up
to 250 mm and PMH-series in diameter range up to
600 mm SMS Meer introduces new standards in
quality, productivity, and flexibility.

Special characteristics
of the bright steel centre
Depending on the machine configuration, bar–to–bar,
coil–to–bar and coil–to–coil operation are possible
for the manufacturing of cylindrical, tapered and/or
double tapered bars. All common steel alloys, round
cast, titanium and other non-ferrous materials can be
processed.
The product program specifically includes:
„„Black bar straightening machines in multiple or
two-roll design
„„Complete bar loading device with unscrambling for
bars as well as coil preparation systems, consisting
of pay-off reel, coil end opener, pre-straightening
and calibrating units for operation mode from coil.

Black Bar Straightening
Two and Multi-Roll Straightener
For straightening of rolled or forged round bars and
thick walled tubes made of steel the product unit
Schumag & Copper of SMS Meer supplies
straightening machines in line with a bright bar centre
or as a separate unit with handling equipment.
Especially with straightness deviations of the raw
material of more than 2 mm within 1 m of the
measured length, straightening before peeling is
recommended.
Two-roll Straightener
For high straightness requirements over the total
bar length, incl. lead and trail ends, we recommend
the use of a two-roll straightener. The main features
of this machines are:
„„Hydraulically movable upper roll to compensate
the ovality of the black bar
„„Scale discharge via emulsion
„„Steel guide ledges with hardened wear segments
for the surfaces in contact with material
„„Good accessibility and easy maintenance thanks
to vertically fitted straightener rolls
MACHINE SIZES
WRP 60S to WRP 160S
„„Working rages Ø 10 mm to Ø 160 mm
„„Throughput speed up to 60 m/min

Multiple–roll straightener
10-roll concept
In order to meet the future requirements, SMS Meer
has developed a multi-roll straightener with 10-rolls.
The machines of the MWR series are characterized
by the following features:

clamping for all top rolls
„„High performance roll and drive concept
„„Good accessibility and high operating comfort
„„Fast change of rolls and reduced down-times for
tool change
„„improved scale removal
„„Environment and operator friendly due to
integrated dust extraction and optimized sound
insulation

Raw Material
Coil
Pay-off reel
For coil weights up to 3,500 kg pay-off reels in
different designs and executions are available.
Coil end opener
Coil end openers to open and pre-straighten the
leading coil end are available in three sizes and
right/left versions.
Feed device movable
in cross direction
Feed device, laterally movable to feed the leading
coil end pre-straightened by the coil end opener into
the pre-straightener.
Manipulator
Manipulator as an alternative to the coil end opener.
Controllable five axes enable safe and flexible
handling of the leading coil end from the moment
of gripping it until it is taken over by the pinch rolls
of the pre-straightener.
The movement axes are controlled by “joy stick”.
Horizontal and vertical
pre-straightener
Straightening combinations, consisting of
„„Horizontal, driven pre-straighter
„„Vertical, non-driven pre-straighter
Calibrating unit
The combination of the plastic deformation effect
during the calibrating process and the simultaneous
twist on the taut wire, removes kinks from even
roll-hardened material. Therefore, it will straight and
it can still roll and be unscrambled after peeling and
cutting to size. The wire is twisted by the inclined
pinch rolls.
Rotary Straightener
Depending on the quality of the raw material
alternatively or additionally to the calibrating unit
a rotary straightener can be installed.

Raw Material
Bar
Bar loading
and unscrambling
To supply bar material from bundles to the system,
SMS Meer supplies tailormade loading systems with
automatic downstream unscrambling. The transport
to the subsequent units is done either by using
discharge slopes or chain conveyors.

MATERIAL TESTING AND
BAR END PROCESSING
Undoubtedly the best quality
Material testing
A testing unit can be integrated into the line to ensure
the required quality of the peeled and straightened
bar. This can consist of the following components:
„„Standard test coil according to the eddy current
method for testing surface point errors
„„Rotating test coil according to the eddy current
method for testing surfaces for point and
longitudinal errors
„„Detection of internal material defects by
ultrasonic
„„Randomized measurement of the rod
straightness
„„Measurement of the diameter
„„Grade and heat treatment verification
Bar end Processing
The machining of bar material in downstream
machines such as automatic lathes often requires a
certain bar end shape to ensure a trouble-free feed
in the lathe.
The relevant bar end machining operation with the
FP-series can take place at the end of the line by
machining the peeled and straightened bar, or to
minimize cutting tool wear upstream of the peeling
machine.
The flexible machine concept enables a multitude of
bar end machining options such as:
„„Face turning
„„Face milling
„„Chamfering
„„Trunnion turning
„„Centering boring
„„Sawing
Some of the advantages of the SMS Meer concept
for bar end machining are:
„„High performance
„„Facing/chamfering in one run
„„Face-milling/chamfering with the same tool
„„Quick tool replacement
