Beschreibung
Zusammenfassung:	The invention relates to the technical field of strip steel annealing, and discloses a reduction annealing furnace for strip steel hot galvanizing, which comprises an annealing furnace body, a feeding roller arranged at a feeding end and a discharging roller arranged at a discharging end of the annealing furnace body, and further comprises a transmission unit arranged in the annealing furnace body, the annealing furnace is used for conveying strip steel in the annealing furnace and sequentially carrying out annealing reduction treatment; the conveying unit comprises first conveying rollers which are arranged at the bottom of the annealing furnace body and are oppositely arranged, and a plurality of groups of first conveying rollers are arranged at equal intervals in the length direction of the annealing furnace body, so that the problem that in the prior art, after nodulation substances appear on the conveying rollers in the annealing furnace body, the furnace needs to be shut down for inspection and the conv
