Abstract

Annealing furnace system with conditioned atmosphere of urgency, characterized in that the source of the hostile atmosphere is closed to the chamber and simultaneously a gas is introduced to neutralize the atmosphere of the chamber with respect to the band, the phase being carried out of closing the source of air and gas to the heating means and simultaneously passing only the gas to the inactive heating means which then serve as nozzles to introduce the gas inside the chamber making the atmospheric gas thereof rich and non-oxidizing with respect to the band metal until normal operation can be continued.
