The
drying of flux before the galvanizing of wires is considered as a significant
operation. However, in many cases the necessity of dryers using either fumes
or hot air is not justified. Indeed, it has been proved that it is absolutely
possible to consider the use of a cold air dryer for average wire speeds.
Made in polypropylene, requiring no foundation works and being
insensitive to corrosion phenomena linked with the manipulation of solutions
rich in chlorides, the dynamic dryer can perfectly be considered as a technology
that can be applied for the pre-treatment of the wires before galvanizing.
Its simple design that can easily be integrated in existing
lines makes it possible to avoid the costly management of the galvanizing fumes
recuperation that is requiring the use of refractory materials, of systems for
the regulation of the fumes coming out of the galvanizing tanks as well as,
as it is very often the case, the digging of big foundations in order to lead
the fumes towards the dryer.
