Abstract

A cooling panel for a metallurgical furnace includes a body with a front face and an opposite rear face, a top face and an opposite bottom face and two opposite side faces. The body has at least one cooling channel therein, the cooling channel having openings in the rear face; wherein, in use, the front face of the body is turned towards a furnace interior. According to the invention, the cooling panel having at least one cooling pipe arranged in at least one elongate recess formed in the front face, where the cooling pipe has an elongate middle section and at either end thereof, an angled branch, the cooling pipe forming the cooling channel, and where the cooling pipe is arranged in the elongate recess such that the angled branches protrude through the openings in the rear face of the body.

First claim

The invention claimed is:

1. A cooling panel for a metallurgical furnace comprising
a body with a front face and an opposite rear face, a top face and an opposite bottom face and two opposite side faces, said body having at least one cooling channel therein, said cooling channel having openings in said rear face; wherein, in use, said front face of said body is turned towards a furnace interior,
at least one cooling pipe having an elongate middle section and at either end thereof, an angled branch, said at least one cooling pipe defining said cooling channel,
wherein said body comprises at least one elongate recess formed in said front face, said at least one cooling pipe being arranged in said at least one elongate recess such that said angled branches protrude through said openings in said rear face of said body.

2. The cooling panel according to claim 1 , wherein said at least one cooling pipe has a front face with a profile which, when arranged in said body, matches a profile of said front face of said body.

3. The cooling panel according to claim 2 , wherein said front face of said body has a structured surface with alternating ribs and grooves and wherein said front face of said at least one cooling pipe has a matching structured surface with alternating ribs and grooves.

4. The cooling panel according to claim 1 , wherein said front face of said at least one cooling pipe is integrally formed with said at least one cooling pipe.

5. The cooling panel according to claim 4 , wherein said at least one cooling pipe and front face are formed by extrusion, machining, casting or 3D-printing.

6. The cooling panel according to claim 1 , wherein said middle section of said at least one cooling pipe has round, oblong or rectangular cross-section.

7. The cooling panel according to claim 1 , wherein said at least one elongate recess and said at least one cooling pipe are formed so as to provide a self-locking arrangement.

8. The cooling panel according to claim 7 , wherein one of said at least one elongate recess and said at least one cooling pipe comprises a protrusion and wherein the other of said at least one elongate recess and said at least one cooling pipe comprises a channel for receiving said protrusion therein.

9. The cooling panel according to claim 3 , wherein at least one of said ribs of said body and at least one of said ribs of said at least one cooling pipe is provided with cooperating through holes, wherein said through holes are in alignment when said at least one cooling pipe is arranged within said at least one elongate recess, and wherein a bolt is arranged through said through holes.

10. The cooling panel according to claim 9 , wherein said bolt comprises threaded shaft ends and wherein nuts are provided for cooperating with said shaft ends.

11. The cooling panel according to claim 1 , wherein said at least one elongate recess formed in said front face is in a direction essentially parallel to said side faces of said body.

12. The cooling panel according to claim 1 , wherein said at least one elongate recess formed in said front face is in a direction essentially perpendicular to said side faces of said body.
