Tata Iron and Steel, India, has awarded
SMS Demag a contract for the
modernisation of its hot strip mill in
Jamshedpur.
For the roughing mill the contract
includes the replacement of the drive
trains, the installation of new hydraulic
adjusting systems, as well as a new
Level 1 automation system with gauge
and width control. For the finishing mill
SMS Demag will supply new drive
trains for mill stands F1 to F5.
The SMS-designed and built compact
hot strip mill went in operation in 1993,
producing around 3.1 million tons of
hot strip per year. Production after the
revamp can be raised to more than
3.5 million tons per year.
The rise in production will be
accomplished by increasing the drive
power in the roughing stand and
finishing mill. An important factor is the
25% rise of power level in the roughing
stand, which allows the number of
passes to be reduced and makes the
design of pass schedules easier.
To be able to transmit the higher
torques, new drive spindles, larger
work rolls and Morgoil® bearings with
higher load-bearing capacity as well as
modified roll chocks will be installed.
In the finishing mill the power of the
motors will be increased by around
10%. SMS Demag will replace the
main gear units of F1 to F4 and the
pinion gear units of F1 to F5 or their
gear wheel sets. On F1 and F2, new
Sieflex® gear spindles will be installed.
A detailed concept was developed
together with Tata Steel in order to
minimise the times of production
stoppages that are needed for the
revamping job.
The roughing stand area will be
modernised in the autumn of 2008 as
part of an 18-day shutdown and work
in the area of the finishing mill has been
scheduled for the summer of 2009
during continuous shutdown periods.

SMS modernisation of Tata mill in India
An important signing commemorating
the 300th CV line ordered took place
between Maillefer SA and Energya
Industries during the Interbuild show in
Cairo, Egypt, in June.
Hesham H El Sewedy, CEO of Energya
Industries, and Pentti Hätälä, CEO of
Maillefer SA, took up the pen for the
event and a handshake between the
two men sealed the deal.
The order represents the 300th complete
CV line sold in the history of Maillefer.
Manufacturing is underway on the
equipment, which is scheduled to ship
from the company’s Finnish facility
during the latter part of this year.
Energya Industries has earmarked the
new Continuous Vulcanization (CV) line
for its Jeddah Cable plant in Jeddah,
Saudi Arabia. Building preparations
and tower construction are underway
to accommodate the line, which
measures around 115m high.
The CV line ordered is a vertical tower
model destined to the production of
high-voltage and extra high-voltage
insulated cables of up to 500 kV and a
cross-section of 3,000mm2.
It incorporates unique technology
for quality production, which is
characterised by cable roundness and
homogeneity across all insulation and
semi-conductor layers.
Maillefer CV lines are designed as best
in class for manufacturing energy
cables that offer long-term reliability in
the field.
An option was signed to deliver an
identical line to the Energya Cables
operations in Egypt where major
expansions are underway to increase
capacity and expand the product range
of Energy Cables.
Maillefer has been a privileged partner
to Energya Industries and, in particular,
Jeddah Cable Company for more than
20 years.
JCC is a leading manufacturer of a
complete range of cable products in
the ME&A region with the most recent
and most modern manufacturing
processes in the region.
A large majority of cable manufacturing
equipment installed originates from
Maillefer. The 300th CV line once again
confirms the high level of confidence
that both partners place in each other.
