Abstract

The present invention proposes a gap-filler insert ( 20 ) for use with cooling plates ( 12, 12′ ) for a metallurgical furnace, the cooling plates ( 12, 12′ ) having a front face ( 14, 14′ ) directed towards the interior of the furnace, an opposite rear face ( 16, 16′ ) directed towards a furnace wall ( 10 ) of the furnace and four edge faces ( 18, 18′ ). In accordance with an aspect of the present invention, the gap-filler insert ( 20 ) comprises a metal front plate ( 24 ) with a front side ( 24 ) facing the interior of the furnace and anchoring means ( 28, 28′, 30, 30′, 32, 34 ) for mounting the front plate ( 24 ) between two neighboring cooling plates ( 12, 12′ ) in such a way that the front plate ( 24 ) extends between the edge faces ( 18, 18′ ) of both cooling plates ( 12, 12′ ), and that the front side ( 26 ) of the front plate ( 24 ) is flush with the front faces ( 14, 14′ ) of both cooling plates ( 12, 12′ ).

First claim

The invention claimed is:

1. A cooling plate arrangement mounted on a furnace wall of a metallurgical furnace, said arrangement comprising:
a first cooling plate and a neighboring second cooling plate, each cooling plate having a front face directed towards an interior of said furnace, an opposite rear face directed towards said furnace wall and four edge faces;
a gap-filler insert arranged between two neighboring cooling plates, said gap-filler insert comprising a metal front plate with a front side facing the interior of said furnace and anchoring means for mounting the front plate between two neighboring cooling plates;
said gap-filler insert being arranged in such a way that said front plate extends between the edge faces of both cooling plates, and that said front side of said front plate is co-linear with said front faces of both cooling plates.

2. The cooling plate arrangement as claimed in claim 1 , wherein said front plate of said gap-filler insert is made from steel.

3. The cooling plate arrangement as claimed in claim 2 , wherein said front plate of said gap-filler insert is made from high wear resistant steel.

4. The cooling plate arrangement as claimed in claim 1 , wherein said anchoring means comprises two lateral legs, each lateral leg being connected to one edge of said front plate, which is in abutment with one edge face of one cooling plate, said lateral legs being in arranged alongside a respective edge face of said cooling plates.

5. The cooling plate arrangement as claimed in claim 4 , wherein said lateral legs each comprise an extension shaped so as to be in abutment with said rear faces of said cooling plates.

6. The cooling plate arrangement as claimed in claim 4 , wherein said front plate of said gap-filler insert and said lateral legs are made from sheet metal.

7. The cooling plate arrangement as claimed in claim 4 , wherein said gap-filler insert is formed in one piece.

8. The cooling plate arrangement as claimed in claim 4 , wherein said lateral legs are welded to said front plate of said gap-filler insert.

9. The cooling plate arrangement as claimed in claim 4 , wherein a gap between two neighboring cooling plates is wedge shaped and wherein said lateral legs of said gap-filler insert are arranged at an angle so as to snuggly fit into said wedge shaped gap.

10. The cooling plate arrangement as claimed in claim 1 , wherein said anchoring means comprises at least one connecting arm connected to said front plate and to a rear plate, said rear plate being in abutment with said rear faces of said cooling plates.

11. The cooling plate arrangement as claimed in claim 10 , wherein said front plate and said rear plate of said gap-filler insert are made from sheet metal and wherein said connecting arm is welded to both said front and rear plates.

12. The cooling plate arrangement as claimed in claim 1 , wherein said gap-filler insert is connected to said cooling plates through form-fit and/or by mechanical means such as bolts or screws.

13. The cooling plate arrangement as claimed in claim 1 , wherein said gap-filler insert is connected to said cooling plates by bolts or screws.

14. The cooling plate arrangement as claimed in claim 1 , wherein said gap-filler insert is connected to said cooling plates by filling a space between cooling plates and furnace wall with backfilling material.

15. The cooling plate arrangement as claimed in claim 1 , wherein said gap-filler insert is arranged between vertical edges and/or horizontal edges of neighboring cooling plates.

16. The cooling plate arrangement as claimed in claim 1 , wherein said gap-filler insert is arranged between horizontal edges of neighboring cooling plates.

17. The cooling plate arrangement as claimed in claim 16 , wherein said cooling plates are arranged in a staggered configuration wherein a vertical gap between two neighboring cooling plates of an upper row is arranged in alignment of a central portion of a cooling plate of a lower row, and
wherein said gap-filler insert arranged between horizontal edges of said cooling plates extends between two edges of said cooling plate of a lower row.

18. The cooling plate arrangement as claimed in claim 1 , wherein said front plate extends over the whole length of a gap between two neighboring cooling plates.

19. The cooling plate arrangement as claimed in claim 1 , wherein said cooling plate is made of at least one of the following materials: copper, a copper alloy or steel.
