Among
all the designs of galvanizing hearths, the metallic tank is showing very significant
assets compared to its ceramic equivalents. However, our customers often only
take into account its slow wear by corrosion effect and do not choose this technology
that is nevertheless adopted by the biggest galvanizers.
Indeed, the heating system that is made by circulation at high
speed of the fumes coming from a special combustion chamber located at the head
of the tank is allowing to minimize the functioning
costs of the line.
The original premix heating system is avoiding the formation
of hot spots as it is allowing the formation of hot fumes at a well-determined
temperature and with short flame, combined with the forced circulation system
of fumes around the lateral walls of the tank.
The accessibility to the wire field in such type of tank is
very easy and is therefore offering the possibility to work either with very
big wire diameters with which the accessibility to the wires is significant,
or with lines at high speed containing a huge number of wires and where the
accessibility of the wires at the exit of the zinc hearth is essential for the
zinc wiping operations.
The metallic galvanizing bath that has been adopted in Europe
by most of the galvanizers is having an economic heating system.
And lastly, the only solution that is industrially reliable
in case of electric heating, i.e. the metallic hearth, is also responding to
the requests of customers by which gas is failing.
