Abstract
The invention relates to a chamber () 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 (), the oxidation chamber comprising oxidation portions () extending over the width and/or length thereof, each portion comprising at least one blow opening () and at least one suction opening () 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.
