Abstract

A device is disclosed for coupling a coolant supply and/or coolant drainage to a roll, especially in a continuous casting installation, wherein the roll includes a journal, which is mounted rotatably in a bearing block, and a lateral recess, extending in the axial direction, and at least one roll cooling channel, through which a coolant can pass. The device includes at least one coolant channel, which can be brought into fluidic connection with the roll cooling channel on the journal side; and a sealing unit for sealing the fluidic connection between the coolant channel and the roll cooling channel, including an inner module and an outer module. The inner module includes a hollow cylindrical element, which can be inserted into the lateral recess of the journal, and which, when viewed in the axial direction, has no flange on the outer side of the journal.

First claim

The invention claimed is:

1. A device ( 1 ) for coupling a coolant supply and/or coolant drainage to a roll ( 2 ), wherein the roll ( 2 ) comprises a journal ( 3 ), which is mounted rotatably in a bearing block ( 4 ), and a lateral recess, extending in an axial direction, and at least one roll cooling channel for conducting a coolant, said device ( 1 ) comprising:
at least one coolant channel ( 11 , 12 ), connectable with the at least one roll cooling channel on a journal ( 3 ) side to form a fluidic connection between the at least one coolant channel and the at least one roll cooling channel; and
a sealing unit for sealing the fluidic connection between the at least one coolant channel and the at least one roll cooling channel, said sealing unit comprising an inner module and an outer module;
said inner module comprising a hollow cylindrical element ( 7 ) insertable into the lateral recess of the journal ( 3 ), said hollow cylindrical element having a first end facing the outer module and a second end facing the roll, said first and second ends having a respective opening, with the opening of the first end having a diameter greater than a diameter of the second end,
said hollow cylindrical element ( 7 ) having no flange on an outer side of the journal, looking in the axial direction.

2. The device according to claim 1 , characterized in that the inner module comprises a securing cover ( 22 ), which in a mounted condition abuts against an end face of the hollow cylindrical element ( 7 ) and is fastened to the journal ( 3 ).

3. The device according to claim 2 , characterized in that the securing cover ( 22 ) secures the hollow cylindrical element ( 7 ) with form fit in the lateral recess of the journal ( 3 ).

4. The device according to claim 2 , wherein the cover is screwed to the journal by means of one or more screws.

5. The device according to claim 1 , characterized in that the inner module further comprises a securing ring ( 98 ), abutting an end face of the hollow cylindrical element ( 7 ).

6. The device according to claim 5 , wherein the securing ring is securable in a groove formed in the lateral recess of the journal.

7. The device according to claim 1 , characterized in that the hollow cylindrical element ( 7 ) in an installed condition comprises a bottom on the second end, looking in the axial direction, with the opening of the second end provided in the bottom.

8. The device according to claim 1 , characterized in that the inner module comprises at least one pin ( 99 ), for securement of the hollow cylindrical element to the journal ( 3 ), the at least one pin ( 99 ) being introduced into a pin opening of the hollow cylindrical element ( 7 ) and a corresponding pin opening of the journal ( 3 ) which is aligned with it.

9. The device according to claim 8 , characterized in that the pin opening of the hollow cylindrical element ( 7 ) is formed in the bottom.

10. The device according to claim 1 , characterized in that the outer module comprises an elastic sleeve ( 8 ), installable in the hollow cylindrical element ( 7 ).

11. The device according to claim 10 , characterized in that the inner module comprises a first slide ring ( 20 ), and the outer module comprises a second slide ring ( 19 ) in frictional contact with the first slide ring to seal off the fluidic connection.

12. The device according to claim 11 , characterized in that the first and second slide rings ( 19 , 20 ) are arranged inside the hollow cylindrical element.

13. The device according to claim 11 , characterized in that the first and second slide rings ( 19 , 20 ) are provided on the end of the cylindrical element opposite the open end.

14. The device according to claim 11 , wherein the first slide ring is firmly connected to the hollow cylindrical element, and the second slide ring is firmly connected to the elastic sleeve.

15. The device according to claim 1 , characterized in that the outer module comprises an insert piece ( 14 ), which is releasably mountable on the bearing block ( 4 ) and which comprises a first channel ( 15 ), which in a mounted condition of the insert piece ( 14 ) brings the at least one coolant channel ( 11 ) into fluidic connection with the at least one roll cooling channel.

16. The device according to claim 15 , characterized in that the insert piece ( 14 ) further comprises a second channel ( 16 ), wherein, in a mounted condition of the insert piece ( 14 ), the first channel ( 15 ) and the second channel ( 16 ) stand in fluidic connection respectively with the first roll cooling channel and the second roll cooling channel.

17. The device according to claim 1 , characterized in that the roll has an axially extending roll bore ( 6 ), in which a tube ( 17 ) is installed, so that inside the tube a first roll cooling channel is formed, and in a gap between the tube ( 17 ) and the roll bore ( 6 ) or a second coaxially extending tube a second roll cooling channel is formed, wherein the device comprises at least two coolant channels ( 11 , 12 ), which are respectively connectable with the first roll cooling channel and the second roll cooling channel to form a fluidic connection respectively with the first roll cooling channel and the second roll cooling channel.

18. The device according to claim 1 , characterized in that the hollow cylindrical element ( 7 ), in an installed condition, does not protrude beyond the journal ( 3 ), looking in the axial direction.

19. The device according to claim 1 , for use in a continuous casting installation.

20. The device according to claim 1 , wherein the first slide ring of the inner module is installed at least partly in a recess of the bottom of the hollow cylindrical element and is thus secured to the hollow cylindrical element.
