Description

In addition, the detachable device between the transverse elements on the outer side of the device and the side plates of the frame is made in the form of a m-step key entering the groove in the transverse element block.

FIG. 1-5 illustrate an apparatus for supporting an ingot.

The guide device comprises a straight vertical section 1, a section 2 of bending rollers, a curved section 3 and the correct device 4. The forming ingot 5 in the area of the guide device changes from a vertical direction to a horizontal one. In frames 6, the groups of upper and lower rollers 7 and 8 are fixed, respectively. The driving rollers 9 are located between these groups of idle rollers. The puller 10 is intended for mounting and dismounting the rollers 7 and 8. The frame 6 is formed by opposite side plates 11 and transverse supporting elements 12 of box-like shape connecting the ends of said plates from the outer side of the curved section of the guide devices. Each support element 12 has a pair of support plates 13. To the inner surfaces of the side plates, and against each pair of rollers 7 and 8, a corresponding pair of guide bars 14 is attached. The rollers 7 are mounted in bearing shells 15 to which the beams 16 are attached. The ends of the beams 16 are connected unit 17. The lower rollers 8 are mounted in bearing shells 18 connected by a crossbar 19. The bushings 15 and 18 are provided with protrusions 20 in contact with the guide bars 14 and forming the movable support of the rollers. The block 17 has openings 21 through which the guide bars 14 pass. The bar 19 is supported on the support plates 13.

In the space between the beams 16, compression springs 22 are installed. The liners 18 have corresponding tides 23. The springs 24 rest abut their ends against the tides 23 and extend between the two upper rollers 7. Support disks 25 are fixed at opposite ends of these rods, in which the ends of the springs 22 abut The other ends of the springs 22 are locked into the respective blocks 17. In the guides 26 on the outer surface of the block 17, transversely sliding splines 27 with steps are mounted. Guide slats 14 have elongated slits 28 in which shnonka 27 enter and are fixed by one of their three ledges. Thus, the keys hold the rollers in the frame, and the springs 22 squeeze them apart and create enough force on the key to hold it in the locked position. By adjusting the setting of the key at different positions of the steps in the slot 28, the distance between the upper and lower rollers 7 and 8 can be changed in accordance with the thickness of the ingot. Accurate roller clearance

can be provided by exposing under the tabs of the gaskets or using wedges.

The blocks 17 have tides 29 which are integral with them with openings on the side opposite to the key 27.

The keys 27 are provided with protruding shoulders with pins 30. The tides 23 on the frame of the lower rollers have holes 31, similar to the holes in the tides 29. The keys and tides are opened from the inside of the guide device.

In order to remove the rollers 7 and 8 from the frame 6, it is necessary to push the two keys 27 inwards towards the center towards the upper rollers 7 so that

so that they get out of engagement with the guide rails 14. Then, the upper rollers cling to tides 29 and pull them out of frame 6. Thereafter, lower rollers cling to tides 23 and also pull them out of the frame.

The pins 30 and the holes in the tides 23 and 29 are intended to engage with a stripper. Various removable devices can be used. If it is necessary to adjust the rollers for casting ingots of various thicknesses, pullers can be used to move the keys 27 or move them manually using a special tool.

Claims (3)

1. A device for supporting an ingot when it is transferred from a vertical to a horizontal direction on a curved part of the machine — continuous casting, containing idle rollers with a mechanism for adjusting their position, mounted rotatably in bearing shells fixed in the side plates of the frame connected to the outside of the device Transverse supporting elements, characterized in that, in order to facilitate the installation and demounting of idle rollers, the bearing inserts of each roller are rigidly connected row and a transverse elements mounted slidably on the guide strips fixed on the inner surface of the frame side plates, wherein the transverse elements, binders The roller bearings on the inner side of the device are connected to the side plates by means of detachable devices, and the transverse elements connecting the bearing bushings of the protruding rollers on the outer side of the device are in contact with the transverse support elements of the frame. 2.
