Annealing furnace and method for annealing steel strands

摘要

The invention relates to an annealing furnace (1) for annealing a steel strand (2), the first heating device (9) for heating the strand (2) during the operation of the annealing furnace (1). And a transport device (4, 5,. 6, 7). The annealing furnace (1) is a first for cooling the outer surface (17) of the strand (2) having the gas guiding device (16) behind the first heating device (9) in the conveying direction (3). A cooling device (13), wherein the gas guiding device (16) moves along the outer surface (17) of the strand (2) during operation of the annealing furnace (1) to cool the strand (2). Arranged to flow.
