Claim:
1. An apparatus for the treatment of a flat steel product, taking place in throughput, comprising: an indirectly heated annealing furnace chamber, having a conveyor device for continuously conveying the flat steel product over a conveyor path leading from an entry of the annealing furnace chamber to an exit of the annealing furnace chamber, and having nozzle arrangements for feeding atmosphere gas, which is reactive in relation to the flat steel product, into the annealing furnace chamber, wherein the nozzle arrangements include a first nozzle arrangement, from which a gas jet, which induces a first gas flow directed towards the entry of the annealing furnace chamber and sweeping over the surface of flat steel product to be treated, emerges during the treatment, and a second nozzle arrangement, from which a gas jet, which induces a second gas flow directed towards the exit of the annealing furnace chamber and sweeping over the surface of flat steel product to be treated, emerges during the treatment, and wherein the first and second nozzle arrangements are provided in the annealing furnace chamber and at least one of the nozzles of one of the nozzle arrangements emits a gas jet which is directed towards the lower side of the flat steel product to be treated, while at least one of the nozzles of one of the nozzle arrangements emits a gas jet which is directed towards the upper side of the flat steel product to be treated.
