Abstract
An arch segment in an arch region of a strand-guiding device guides and deflects a cast strand made of metal into the horizontal after leaving a mold. The arch segment has an upper frame and a lower frame, on each of which a plurality of strand-guiding rollers are rotatably mounted. The upper frame and the lower frame are connected together such that the respective strand-guiding rollers thereof are arranged opposite one another in a mutually spaced manner and define an arch-shaped guide channel for guiding the cast strand. In order to reduce bulging of the cast strand in the arch region of the strand guide, at least one of the strand-guiding rollers on the upper frame and/or the lower frame is designed in the form of an axle roller.

An arch segment (160) in an arch region of a strand-guiding device (150) for guiding and deflecting a cast strand (200) made of metal into a horizontal orientation after leaving a mold (140), comprising:
- a plurality of strand-guiding rollers (170) which are arranged opposite one another in a mutually spaced manner and define an arch-shaped guide channel for guiding the cast strand (200);
- an upper frame (162) on which upper ones of the plurality of strand-guiding rollers (170) are rotatably mounted;
- and
- a lower frame (164) on which lower ones of the plurality of strand-guiding rollers (170) are rotatably mounted,
- wherein the upper frame (162) and the lower frame (164) are connected together such that their respective oppositely arranged strand-guiding rollers (170) define the arch-shaped guide channel,
- wherein at least one of the upper ones of the plurality of strand-guiding rollers (170) and at least one of the lower ones of the plurality of strand-guiding rollers (170) is a driven strand-guiding roller (170),
- wherein the driven strand-guiding roller (170) is a driven journal roller,
- wherein some of the upper ones of the plurality of strand-guiding rollers (170) and some of the lower ones of the plurality of strand-guiding rollers (170) are non-driven strand-guiding rollers (170),
- wherein at least some of the non-driven strand-guiding rollers (170) are non-driven axle rollers with a fixed axle, and
- wherein the driven journal rollers have a larger diameter than the non-driven axle rollers.
