Problems solved by technology

[0010] But the example of the cooling box described in DE4035894C1 also has a disadvantage, because the explosive joining of the metal cover plate with the cooling tube does not take place and the heat transfer is thus affected

Embodiment Construction

[0045] figure 1 A cooling element 1 is shown for installation into the wall of a furnace. The cooling element 1 comprises a U-shaped curved cooling tube 2 which, in a manner not shown, passes through the furnace shell and protrudes into the furnace interior. The cooling tube 2 has two ends 3 , 4 which are connected to a common plate-shaped support element 5 . Depend on figure 2 and 3 It can be seen that the cooling tube 2 does not pass through the carrier element 5 with its end 3 , but is only fastened to the opening of the carrier element 5 . A socket 6 is fastened to this opening of the carrier element 5 by welding. The connection piece 6 is used for coupling with other pipe sections in a manner not described.

[0046] In the exemplary embodiment, the connecting piece 6 is made of steel, while the cooling pipe 2 is made of copper material. Firstly, the connecting pipe 6 is connected with the cooling pipe by welding. This can preferably be achieved by friction welding...

Abstract

The invention relates to a cooling element for a melting furnace, having at least one cooling pipe for passing through a coolant, and having a support element (21) to which the at least one cooling pipe (2, 20) is fastened, wherein at least one cover plate (22, 23) is welded to the at least one cooling pipe (2, 20), wherein the at least one cooling pipe (2, 20) has at least one bead (14, 15) which extends in the longitudinal direction of the at least one cooling pipe (2, 20) and to which the at least one cover plate (22, 23) is welded.

Description

technical field [0001] The invention relates to a cooling element for a furnace according to the features of the preamble of claim 1 . Background technique [0002] Furnaces typically include vessels made of steel. In order to protect the steel container, a water cooling element is fixed inside the wall of the container. The intermediate space between the water cooling elements is filled with refractory material, such as prefabricated bricks or cast material. The surface in front of the cooling element is also shielded in this way. [0003] Water-cooled cooling elements of the prior art are roughly divided into two types, one of which has planar cooling devices which cover substantially the entire inside of the furnace. These cooling elements are generally made of copper and have a hot-forged structure, which is drilled deep for the conduction of the cooling water. Elements made of gray cast iron comprising cast-in tubes are also known. Cooling elements of this construc...
