The invention comprises a non-rotating shaft for supporting a mechanical element of a roll segment in a continuous casting machine, having an essentially circular cross-section. The circular cross-section presents a portion having a smooth peripheral, wherein the distance between any point of the portion and a center of the circular cross-section is shorter than a radius of the circular cross-section. Furthermore, the circular cross-section presenting the portion extends axially, which defines a section of the shaft meant to a least partly receive the mechanical element, and the section of the shaft is meant to receive a load at least partly at the portion. In addition, according to a second aspect, the invention comprises a segment roll for a continuous casting machine, which comprises the non-rotating shaft according to the first aspect.

Non-rotating shaft for a continuous casting machine

A segment roll for use in a continuous casting machine includes a number of roll segments axially spaced apart and supported in bearings on a non-rotating shaft. Each roll segment is a self-contained unit including a sleeve-shaped outer mantle, an internal sleeve disposed coaxially within the outer mantle, and a bearing assembly disposed radially between the outer mantle and the inner sleeve within an annular recess disposed at each end of the roll segment. Each bearing assembly is spaced from an inner envelope surface of the internal sleeve and includes a bearing and a seal, wherein the internal sleeve is in non-rotatable contact with the non-rotating sleeve.
