Carried
out under atmosphere, the austenitizing or annealing of wires in a tubes furnace
is requesting some well-designed equipments.
Indeed, the tubes that have to resist to high temperatures
must be heated homogeneously and their lifetime must be as long as possible.
Without casting doubt over the utility of a degreasing of the
wires before the treatment in the furnace in order to avoid any blocking of
the tubes, the heating mode of these tubes is remaining a crucial point in the
design of the furnace as well as the easiness of their replacement.
With an original solution of gas
heating that is giving you the possibility to have an equipment with
relatively low functioning costs, FIB can offer you a heating
solution with gas or electricity.
Advantages:
-
Easy replacement of the tubes
-
Great stability of the temperatures
of the furnace
-
Solutions for a gas or electrical
heating
-
Possible exploitation of gas as
combustible means, which is less expensive than electricity
regarding the exploitation costs
-
Control of the dilatation of the tubes on
big lengths (up to 14 m length)
-
Option: protective gas mixer
-
In the case of tubes furnaces for an exploitation
in oil tempering: special junction in order to avoid the oxidation
of the wires between the furnace and the oil tempering
