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?).

Abstract: A cooling plate (10) for a metallurgical furnace in accordance with the present invention has a panel-like body (12) with a front face (14) and an opposite rear face (16), an upper edge (22) and an opposite lower edge (24), and a first side edge (18) and an opposite second side edge (20). The front face (14) is provided with grooves (32) extending between the first and second edges (18, 20), the grooves (32) forming lamellar ribs (34) on the front face (14), each rib (34) having a crest (37) and adjoining sidewalls (39, 39?), a base (38) being arranged in the groove (32) between two neighboring ribs (34). In accordance with an important aspect of the present invention, at least one of the grooves (32) is provided with a metal insert (40) arranged against at least one of the sidewalls (39, 39?).

Abstract: A cooling plate for a metallurgical furnace includes a body with a front face, an opposite rear face (16), four side edges and at least one coolant channel extending from the region of one side edge to the region of the opposite side edge, where a bent connection pipe connects at least one extremity of each coolant channel for coolant fluid feed or return, and the bent connection pipe is sealingly connected with the extremity of the associated coolant channel within a respective recess in the body that is opened toward the rear side, where the coolant channel opens in the recess in a connection surface beveled towards the rear side; and the bent connection pipe does not extend laterally beyond the corresponding side edge.

Abstract: A cooling plate (10) for a metallurgical furnace in accordance with the present invention has a panel-like body (12) with a front face (14) and an opposite rear face (16), an upper edge (22) and an opposite lower edge (24), and a first side edge (18) and an opposite second side edge (20). The front face (14) is provided with grooves (32) extending between the first and second edges (18, 20), the grooves (32) forming lamellar ribs (34) on the front face (14), each rib (34) having a crest (37) and adjoining sidewalls (39, 39?), a base (38) being arranged in the groove (32) between two neighboring ribs (34). In accordance with an important aspect of the present invention, at least one of the grooves (32) is provided with a metal insert (40) arranged against at least one of the sidewalls (39, 39?).

Abstract: A method for manufacturing a cooling plate (10) for a metallurgical furnace comprising the steps of providing a slab (11) of metallic material, the slab (11) having a front face (14), an opposite rear face (16) and four side edges; and providing the slab (11) with at least one cooling channel (30) by drilling at least one blind borehole (40) into the slab (11), wherein the blind borehole (40) is drilled from a first edge (22) towards an opposite second edge (24). In accordance with an important aspect of the present invention, the method comprises the further steps of deforming the slab (11) in such a way that a first edge region (46) of the slab (11) is at least partially bent towards the rear face (16) of the slab (11); and machining excess material from the front and rear faces (14, 16) of the slab (11) to produce a cooling plate (10) having a panel-like body (12) wherein an opening to the cooling channel (30) is located in the rear face (16).

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?).

Abstract: A method of manufacturing a stave cooler for a metallurgical furnace including supplying a metal plate having an inward side for facing the inside of the furnace and an opposite outward side; supplying at least one coolant pipe; establishing a thermo-conductive contact between the coolant pipe and the metal plate; providing the coolant pipe with a flattened face and externally fixing the flattened face to the metal plate on the outward side for establishing the thermo-conductive contact.
