Chamber furnaces for
wire treatment
Horizontal chamber furnaces from ILES
are produced in two distinct series
with maximum working temperatures
of 500°C and 700°C. They are used for
stress-relieving, tempering, structural
hardening, ageing and annealing of
non-ferrous materials.
The main characteristics of the furnaces
are high thermal efficiency, achieved by
thermal insulation with ceramic fibres in
several layers at differentiated density,
and mass-less wire heating elements
placed directly in the air circuit.
A vitrifying system, with the special
design of the internal deflector and of
the high-revolution fan for air circulation,
maintain temperature uniformity of ±5°C
inside the treatment chamber.
The furnaces can be supplied with
several options including a timer, safety
protection against over heating, an
automated thermal cycle – no operator
required – and 4, 6, 8 or 12 post external
storage units, with loading system and
automated thermal cycles.
The standard equipment for all the
models includes the PLC operator panel,
microprocessor temperature controllers
and EDP network connection.

Billet caster at JSW
JSW Steel Ltd (JSW), located in
Toranagallu in the state of Karnataka
in India, has commissioned the first
eight-strand billet caster on the Indian
subcontinent with SMS Concast, Zurich
(Switzerland), a company of the SMS
group, Germany. The billet caster
delivered by SMS Concast is part of
JSW’s expansion programme ‘Cheetah’
which will bring the production capacity
at the Vijayanagar works to 7million tpy.
The billet caster comprises the
technology and equipment for open
and submerged casting. It is designed
for a production capacity of 1.7million t
of billets per year.
The high-speed caster contains the
convex mould technology, electro-
magnetic mould stirring, hydraulic
mould oscillation and the Conseal IV
technology. The production process is
directly tuned to the downstream wire
rod and rebar rolling mills with hot
discharging route.
