The invention relates to a chamber (1) for the controlled oxidation of metal strips in a furnace for annealing a continuous production line of strips which are hot-coated, for example by galvanisation, the oxidation chamber allowing the oxidation of the metal strips by means of an oxidising gas injected on at least one of the faces of a strip (15), the oxidation chamber comprising oxidation portions (17) extending over the width and/or length thereof, each portion comprising at least one blow opening (4) and at least one suction opening (5) between which an oxidising gas circulates, each portion being controllable in a different way so as to adjust the oxidation induced on the strip over the width and length of the oxidation chamber.
An oxidation chamber for controlled oxidation of metal strips in an annealing furnace of a continuous production line for hot-coated strips, the oxidation chamber comprising oxidizing portions extending over a width and/or length of the oxidation chamber, each oxidizing portion comprising at least one blowing port through which an oxidizing gas is injected into the oxidation chamber for contact with the metal strip and at least one suction port for removing the oxidizing gas from the oxidation chamber after the oxidizing gas has contacted the metal strip, the oxidizing gas circulating within the oxidation chamber between the at least one blowing port and the at least one suction port, and wherein the at least one blowing port and the at least one suction port of each of the oxidizing portions are configured to be controlled separately to adjust an oxidation induced on the metal strip over the width and length of the oxidation chamber.
An oxidation chamber for controlled oxidation of metal strips in an annealing furnace of a continuous production line for hot-coated strips, the oxidation chamber comprising:
