Abstract (en)

A roll (20) that can be disposed before and/or after a quenching zone (4) of a continuous annealing furnace is provided. The roll (20) has a predetermined profile satisfying Lc ≥ 0.7 x Wmin;R = 0.1 x 10<-3> to +0.2 x 10 <-3>; and TR ≥ 20, wherein Lc represents the length (mm) of a flat portion (22) in the center of the roll (20), Wmin represents the minimum width (mm) of a steel strip (1), R represents the inclination of tapered portions (24) disposed at two sides of the roll (20), and TR represents the radius of curvature (m) of boundaries between the flat portion (22) and the tapered portions (24). The roll (20) can be used as a hearth roll (9) and/or a bridle roll (10) disposed at the entry side and/or the exit side of the quenching zone (4). <IMAGE>
