Problems solved by technology

[0008] In this embodiment, although it is also possible in the mounted state of the bearing cap—that is to say without having to dismantle the bearing cap for replacement—the coolant pipe including the seal assembly can be replaced, but the The seal assembly consists of many parts, such as a spring set, a so-called "floating slip ring", a seal carrier and two cooperating slip rings, making it impossible to quickly replace said seal assembly

Embodiment approach

[0034] figure 1 A first embodiment of a cooled roller in a continuous casting plant, which is designed as a strand guide roller 1 for guiding and supporting a cast product, is shown. In this case, the cast product is supported above and below the center plane of the cast product by strand guide rollers, wherein a plurality of strand guide rollers are supported in a strand guide section. The roller body 4 is supported at least twice each by means of a bearing 6 designed as a self-aligning roller bearing, wherein the bearing 6 transmits the forces acting on the strand guide roller 1 to the bearing body 2, and then transferred to the slab guide section. In order to improve the service strength of the slab guide roller 1 on the one hand, and to cool the cast product by means of the slab guide roller 1 on the other hand, the slab guide roller 1 is provided with a cooling device. In this case, the coolant, water, is conducted from the section to at least one coolant channel 3 in ...

Abstract

The invention relates to a bearing arrangement and a rotary inlet for a cooled roller. The aim of the invention is to provide a simple rotary inlet for a cooled roller while maintaining high reliability, such that firstly a seal element has only a small number of individual parts, and secondly a fast exchange of the seal element is possible. Said aim is achieved by means of a device of the type specified in the introduction, in which the coolant pipe (9) is connected to the roller body (4) via at least one sleeve-shaped sealing element (10) with an inner and an outer lateral surface (11,12), wherein the inner lateral surface (11) is sealingly connected to the stationary coolant pipe (9) and the outer lateral surface (12) is sealingly connected to the rotating roller body (4); and the sealing element (10) has at least one, preferably at least two static seal(s) (13) on the outer lateral surface (12) thereof, and has at least one, preferably at least two, dynamic seal(s) (14) on the inner lateral surface (11) thereof.

Description

technical field [0001] The invention relates to a support structure and a rotary introduction mechanism for cooled rolls. Background technique [0002] From document EP1048880A1 is disclosed a support structure for cooled rolls and a rotary lead-in mechanism comprising: [0003] - bearing body; [0004] - a roller-shaped roller body with a central coolant channel for the cooling medium at least on the inlet side; [0005] - at least one bearing for rotatably supporting said roller body relative to said bearing body, wherein forces are transmitted from said roller body through said bearing to said bearing body; [0006] - an external bearing cap releasably connected to said bearing body; and [0007] - a coolant pipe connected to the outer bearing cap for introducing a cooling medium into the coolant channel of the roller body. [0008] In this embodiment, although it is also possible in the mounted state of the bearing cap—that is to say without having to dismantle the b...
