Abstract (en)
[origin: WO2012103563A1] The subject matter of said invention is formed by a method for controlling the atmosphere in a protective gas chamber (2) for the continuous treatment of metal strips (3). Here, the metal strip (3) is guided into and out of the protective gas chamber (2) via locks (4). At least one lock (4) has at least two sealing elements (5, 6) for the metal strip (3) which runs through it, with the result that a sealed chamber (7) is formed between the two sealing elements (5, 6). According to the invention, the gas pressure (P2, PD) is measured in the protective gas chamber (2) and in the sealed chamber (7) of the lock (4) and the pressure (PD) in the sealed chamber (7) is regulated, to be precise in such a way that, during operation, the differential pressure between the protective gas chamber (2) and the sealed chamber (7) is kept as far as possible to an optimum value.
