Luvata introduces longest
jointless hollow conductor
LUVATA, a leader in metal solutions
manufacturing and related engineering
services, has introduced MileonTM,
claimed to be the longest seamless
hollow conductor available.
Hollow conductors are used in
a number of applications including
particle accelerators, MRI scanners,
plasma research devices and induction
furnaces. Unlike traditional hollow
conductors, Mileon gives manufacturers
the option for large continuous coils or
the flexibility to specify the optimum
length, reducing the amount of scrap
and packaging materials required.
Mileon hollow conductors are
completely jointless and produced in
long continuous lengths, measured
in hundreds or even thousands of
metres. Made from high purity oxygen-
free copper, Mileon delivers electrical
conductivity of 101-102 %IACS and
thermal conductivity of 390W/km.
The newest cancer treatment
instruments are carbon-particle therapy
instruments, which are used to direct
a concentrated beam into a tumour
without hurting the surrounding healthy
tissue. These instruments use powerful,
water-cooled resistive magnets wound
with hollow conductors. “Every joint in
a magnet causes not only additional
work, but they’re also a major risk for
leaks despite very careful inspection of
the joint,” commented Paula Tappola,
Luvata product manager for hollow
conductors. “In most cases a leak inside
a magnet cannot be repaired and the
whole magnet must be replaced with a
new one, causing significant down time
and substantial costs.”
Commonly requested dimensions
and shapes of Luvata hollow conductor
profile tools includes round, oval, square
and rectangle.
Luvata’s solutions are used in
industries such as renewable energy,
power generation, automotive,
medicine, air-conditioning, industrial
refrigeration and consumer products.

CMI to supply
tube furnace to
Veridiam
CMI Industry has gained an order
from Veridiam, Inc, USA, for a roller
hearth furnace for the bright annealing
of stainless steel tubes dedicated to
nuclear and medical applications. CMI
Industry Americas will manufacture
the furnace in its workshop in Salem,
Ohio, USA. Full commissioning of the
furnace is scheduled to be completed
by November.
The contract will be managed by
CMI Industry Americas. Dave Boyce,
CEO, commented, “With this order, CMI
Industry demonstrates its added value
in the market of bright annealed tubing,
and in the tubing heat treat market in
general.”
Veridiam, one of the leaders in the
stainless steel tubing industry for both
nuclear and medical applications,
chose the best technologies to reach
its specific metallurgical and surface
quality requirements.
Components included in
the furnace are natural
gas fired combustion
system utilising ceramic
(SiSiC) radiant tubes
throughout; self-recuper-
ative burners with efficiency of
approximately 70 per cent; high purity
furnace insulation to allow constant
100 per cent hydrogen atmosphere
operation; atmosphere jet cooling
system with variable frequency control
for rapid jet cooling; main gas safety
and atmosphere safety systems; and
PLC control system with touch screen
interface.
CMI Industry designs, supplies
and modernises mechanical, heat
and chemical treatment equipment
and industrial efficiency solutions.
In particular, the company supplies
cold complexes to steel-makers, with
unparalleled references in rolling
mills, coating lines, furnaces, chemical
treatment installations and special
equipment.
CMI designs solutions for reducing the
environmental footprint of all types of
industrial installations, and its solutions
are adapted to the specific needs of
each customer.
