english technology news
Decalub, France, has introduced the new
generation DCCD (dry cleaning, coating
and drawing) process which eliminates
the most costly parameters in the wire
drawing process, including elimination of
acid and pre-coating chemicals.
As a consequence, the new process offers
significant downstream benefits enabling
the users to target a total saving of 50-
65% in production costs of drawn wire.
The system allows immediate substantial
cost savings in the most demanding
drawing applications, including spring
wire, high-tensile rope wire, bead wire, PC
strand wire, AL cladded wire, plating wire,
bright wire, CO2 welding wire, etc.
Following the scale cracking by rod
reverse bending and rod smooth brush
cleaning, upon automatically controlled
brush pressure, the powerful multi-
function LVC/PDH system, installed
in the first draft, permits in-line high-
performance dry coating and lubrication
of H/C or L/C mechanically descaled bare
rod, with liquefied standard dry lubricants
the viscosity of which is automatically
controlled during the drawing operation,
completely eliminating traditional wet
pre-coating chemicals.
One of the typical applications of the
DCCD process consists in direct drawing
from 5.5mm diameter mechanically
descaled bare rod, with 0.83/0.88% carbon
content, without pre-coating, with an
output of 2.2 tons per hour and with a die
life of 200 tons per die in the first draft.
Full lubricant film achieves frictionless
drawing by physical separation of wire-die
contact in all drafts, enabling diewear of 0.30
micron per ton of wire drawn, with virtually
no speed limitation, dependent mainly on
rod pay-off andwire take-upmodes.

Resistance measurement and Resistomat®
are terms that belong together.
Burster has launched a new Resistomat®
2316 – a tough, universal and compact
resistance measurement device that suits
all applications in industry surroundings
as well as in laboratory conditions.
The new measurement device combines
precision as well as easy handling and
system integration capability quite
perfectly.
The instrument measures resistances in
the range of 2,0000 mΩ up to 200,00 kΩ
with an accuracy of 0.03 % rdg, with the
resolution in the smallest range reaching
0.1 μΩ.
A specially developed measurement input
protection allows the measurement of
inductive samples like electric motors and
transformers as much as coils with iron
cores.
The measurement of heating elements,
fuses, switch and relay contacts or cables
and wires are just a few further application
fields.
Autorange, temperature compensation of
the test sample, cable fraction detection
and thermovoltage compensation are
self-evident.
For the integration into fully automatic
test stations the instrument features a PLC
and RS232/USB interface.
Thanks to the large and backlit LCD
display, the measuring value can be
easily read from a major distance in dim
production halls, as well as in direct
sunlight.
The simply designed choice of the
different measuring parameters is affected
via an elaborate operation menu that
provides five languages – English, French,
Spanish, Italian and German.

Tenova’s new slab
furnace in operation
After the successful completion of the
erection and start up phase – jointly
carried out by Tenova LOI Italimpianti,
Techint and Ternium Hylsa – the new
slab reheating furnace at the Ternium
steel plant in Monterrey, Hylsa,
Mexico, has been put into operation.
The new furnace features the latest-
generation technology using the new
FlexyTech® Tenova flameless burners
that combines reduced consumption
and extremely low emissions with a
reheating quality at today's highest
levels.
These burners have already been
successfully installed by Tenova LOI
Italimpianti on recent high capacity
reheating furnaces.
The new furnace will replace the old
battery of pit furnaces, currently in
the dismantling phase, guaranteeing
an increase in production capacity.
The contract for engineering work and
supply of the advanced technology
plant components was awarded to
former Techint Technologies Furnace
Business Unit based in Genoa (Italy),
now Tenova LOI Italimpianti, which
completed the project on schedule.
The contract covered support for
plant installation, testing, start-up,
and related services.
