ATE recently developed two induction
heating systems for treating wires in
parallel, with the names IMW (independent
control wire) and CMW (common control
wire).
Through the use of advanced technologies
in the field of power electronics, these
systems represent a sophisticated and
efficient solution for the simultaneous
heating of multiple wires with the same or
even with different diameters.
The main characteristics of the two systems
are:
•
for the IMW system the possibility of
heating multiple wires of different
diameter separately, wire by wire, with
the same or different temperatures and
speeds (upon request)
•
for the CMW system the possibility of
heating wires of the same diameter
to the same temperature or wires of
slightly different diameter to almost the
same temperature, taking account of a
suitable‘velocity x diameter’ (DV)
Compared to other types of furnaces, such
as resistance, gas, fluid bed or lead bath
heaters, the IMW and CMW multi-wire
induction heating systems have the
following advantages:
• no environmental pollution
• more compact
• higher efficiency
• optional closed loop process control
Besides wires, the systems are also able to
treat metal strips or bands. In these cases
the systems are identified with the codes
IMS or CMS, instead of IMWor CMW.
In addition to ferrous materials, the systems
can heat aluminium, copper, brass, etc, with
efficiency values proportional to the type of
material.
The compactness of the heating units
allows them to be easily installed in limited
spaces and, above all, in existing lines in
which overall dimensions are binding.
The frequency converter, the heat
exchanger and the control panel which
complete the system can be positioned
remotely in available spaces, even at a
certain distance from the heating unit.
The IMW and CMW multi-wire induction
heating systems can be used in various
industrial processes, some of which are:
•
annealing (max temperature of around
720°C)
•
stress relieving (max temperature of
around 400°C)
•
diffusion/brass coating of wires for steel
cord (max temperature 550-600°C)
•
preheating for galvanising (around
500°C)
•
preheating for painting or coating (max
200-250°C)
•
preheating before an existing gas
furnace in the case of increased
productivity of the system
The IMW/IMS and CMW/CMS systems are
completely modular and can heat a variable
number of wires.
