This original heating technique
of the furnaces allowed at that time some original furnace
constructions, the use of which already allowed a very
rapid heating under atmosphere conditions that could
be realized before only thanks to muffles, tubes and
protective atmospheres.
The rapid heating of the wires under
atmosphere had been invented by FIB.
Immediately, some installations were
supplied to the Netherlands, to France and to Italy.
So has the technique of open fired patenting been developed
in France thanks to a customer-supplier collaboration
and this in order to manufacture the wires necessary
for the suspension cables of the Tancarville bridge. |
