Abstract

The invention relates to a charging installation ( 1 ) of a metallurgical reactor, with a cooling assembly ( 4 ) disposed for cooling a reactor side of the charging installation ( 1 ). In order to facilitate the installation and maintenance of a heat protection shield in a charging installation of a metallurgical reactor, the cooling assembly ( 4 ) comprises a plurality of cooling panels ( 10 ), each cooling panel ( 10 ) comprising at least one coolant channel ( 12 ). The channel ( 12 ) is formed as a groove in the base plate ( 11 ), which groove is covered by a cover plate ( 13 ) mounted on the base plate ( 11 ).

First claim

The invention claimed is:

1. A charging installation of a metallurgical reactor, comprising:
a cooling assembly disposed for cooling a reactor side of the charging installation,
wherein the cooling assembly comprises a plurality of cooling panels,
wherein each cooling panel comprises a base plate in which at least one coolant channel is formed,
wherein the coolant channel is formed as a groove in the base plate,
wherein said groove is covered by a cover plate mounted on and elevated on top of the base plate,
wherein the coolant channel has a meandering structure and the cover plate has a meandering structure replicating the shape of the coolant channel, the meandering structure being configured to reduce the risk of a weld disposed between the cover plate and the base plate from breaking whereby the cover plate follows the movement of the coolant channel, and
wherein a plurality of eyelets are disposed on an upper side of the base plate, such that the cooling panel is configured to be removable.

2. The charging installation according to claim 1 , wherein each cooling panel is mounted by a detachable connection.

3. The charging installation according to claim 1 , wherein the base plate is made of metal.

4. The charging installation according to claim 1 , wherein each panel comprises at least one coolant pipe which is connected to the coolant channel.

5. The charging installation according to claim 1 , wherein coolant channels of different panels are connected in parallel to a coolant supply.

6. The charging installation according to claim 1 , wherein at least one heat protection element is mounted to each cooling panel.

7. The charging installation according to claim 6 , wherein the heat protection element comprises a plurality of heat protection tiles, said tiles being disposed adjacent to each other along a surface.

8. The charging installation according to claim 7 , wherein the heat protection tiles comprise a support structure on which a refractory material, is disposed.

9. The charging installation according to claim 7 , wherein a gap is arranged between neighbouring heat protection tiles and wherein the gap is filled with a material which is volatile under the operating temperatures of the metallurgical reactor.

10. The charging installation according to claim 8 , wherein the support structure comprises a mesh on which the refractory material is disposed.

11. The charging installation according to claim 1 , further comprising a casing for a gear assembly and the cooling assembly configured to protect an annular bottom surface of the casing.

12. The charging installation according to claim 7 , wherein the cooling panels are mountable and dismountable from inside a casing for a gear assembly and the cooling assembly configured to protect an annular bottom surface of the casing.

13. The charging installation according to claim 7 , wherein a hoist device for handling the panels is disposed inside a casing for a gear assembly and the cooling assembly configured to protect an annular bottom surface of the casing.

14. A cooling assembly for a charging installation of a metallurgical reactor, said cooling assembly disposable for cooling a reactor side of the charging installation and comprising:
a plurality of cooling panels, each cooling panel comprising a base plate in which at least one coolant channel is formed,
wherein the coolant channel is formed as a groove in the base plate, said groove being covered by a cover plate mounted on and elevated on top of the base plate, and
wherein the coolant channel has a meandering structure and the cover plate has a meandering structure following the meandering structure of the coolant channel, the meandering structure being configured to reduce the risk of a weld disposed between the cover plate and the base plate from breaking whereby the cover plate follows the movement of the coolant channel, and
wherein a plurality of eyelets are disposed on an upper side of the base plate, such that the cooling panel is configured to be removable.

15. A cooling panel for a cooling assembly disposable for cooling a reactor side of a charging installation, said cooling panel comprising:
a base plate in which at least one coolant channel is formed,
wherein the coolant channel is formed as a groove in the base plate, said groove being covered by a cover plate mounted on and elevated on top of the base plate, and
wherein the coolant channel has a meandering structure and the cover plate has a meandering structure following the meandering structure of the coolant channel, the meandering structure being configured to reduce the risk of a weld disposed between the cover plate and the base plate from breaking whereby the cover plate follows the movement of the coolant channel, and
wherein a plurality of eyelets are disposed on an upper side of the base plate, such that the cooling panel is configured to be removable.
