framag’s latest technology
for cold circular saws
IN 2012 framag, a company supplying
the latest cold circular saws for all
types of steel, was commissioned by
Schöller Bleckmann Oilfield Technology
GmbH (SBOT) to replace two existing
band saws with a new, ultra-modern
KKS 1000 cold circular saw.
The aim was to reduce the cutting
time for the high- and ultra-high-alloyed
steels to be cut at SBOT, while at the
same time increasing the service life
of the saw blades. Both the price/
performance ratio offered and the
results achieved in previous test cuts
with the material used prompted SBOT
to award the contract for supplying the
sawing system to framag.
The KKS 1000 is a cold circular saw
suitable for a maximum diameter of the
billet to be split of up to 380mm and is
capable of efficiently sawing low-alloyed
to high-alloyed steels with short cycle
times resulting in high productivity. The
system is equipped with a saw blade
with brazed teeth and an additional
coating.
Any slivers of material that are stuck to
the saw blade are removed with a brush
and the blade cooled. The complete
sawing cycle, including feeding of the
billets and removal of the finished cut
parts, is fully automated.
During commissioning of the system
in 2013 and over a period of about
six months following that, the cutting
parameters and the tooth geometry of
the saw blades used were perfected
such that the tools of the cold circular
saws now have a service life that is
roughly 200 per cent longer than those
of the previous band saws.
The newly installed cold circular saw
from framag also boasts roughly 100
per cent higher productivity than the two
previous band saws combined.
The cold circular saw supplied by
framag has enabled SBOT to saw the
challenging material grades that are
required for drill rods by suppliers to the
oil industry efficiently, cost-effectively
and with a high cut quality.
Mr Ehn, production manager at SBOT,
said: “The framag saw was ordered
following tests which showed it to be the
best saw in terms of cut quality, blade
service life and automatic operation.
The KKS 1000 model is used in place
of three band saws. After a year of
operation, the decision has proved to be
the right one.”

Induction technology for OCTG
pipe end heating applications
INDUCTOTHERM Heating & Welding
Ltd recently supplied its range of IROSS
Fluxmanager equipment to a number of
leading pipe manufacturers within the
OCTG sector.
The IROSS Fluxmanager is designed
for use in an array of pipe end heating
applications for a variety of tubular
goods including drill pipe, casing and
API pipe.
Suited to the OCTG sector, the IROSS
Fluxmanager system is specifically
designed for use in applications such
as preheat for swaging, hardening,
annealing, removal of coatings and
curing, friction welding and stress
relieving.
The patented Fluxmanager unit
utilises an efficient 50/60Hz low
frequency system, which provides deep,
uniform temperature distribution, ID/OD,
both laterally and longitudinally along
extended lengths of pipe ends.
The pipe end exits the coil immediately
with a repeatable temperature uni-
formity of ±25°C (77°F) – no soak time
is required.
The IROSS Fluxmanager system
has quickly become recognised
and adopted into the OCTG sector
as standard equipment and when
compared with traditional medium
frequency pipe end heating techniques,
the IROSS Fluxmanager allows greater
control of end heating, with a shaped
intensifier to concentrate power on the
work piece. The system heats within
tight specifications at a reduced cycle
time and easily adapts to OD variation.
Additionally, only four coil sizes are
required to cover the entire range of
OCTG pipe diameters, but specific coil
diameters are available.
The shaped flux concentrator
allows for complete repeatable results
even when the pipe is placed non-
concentrically in the coil itself.
Infrared, thermal imaging and intuitive
data logging functionality can be
specified by the customer in order to
satisfy the stringent quality requirements
within the OCTG market.
