The vertical annealing furnace for the continuous bright annealing of a metal strip guided through the furnace comprises: a vertically disposed muffle having a strip entry side and a strip exit side, the muffle having the freedom to expand in a longitudinal direction, and the muffle being disposed such that the strip entry side is situated at a top side of the muffle and the strip exit side is situated at an underside of the muffle; heating structure for externally heating the muffle; bearing structure for fixedly supporting the underside of the muffle such that it is delimited downwards in the longitudinal direction; an expansion section being provided on the top side of the muffle for taking up thermal expansion in the longitudinal direction of generally the entire muffle; and vertically movable support structure for exerting an upwardly directed support force on the muffle, the vertically movable support structure being connected to an upper part of the muffle.
