Problems solved by technology
The protective effect of the refractory lining depends largely on the successful installation, in most cases the cooling performance of the elements cannot be fully utilized
In addition, the known cooling element has the disadvantage that the slots for fixing the refractory material are positioned horizontally in the furnace
In this way, the movement of the thermal expansion of the supporting brickwork used in the furnace floor and the movement of the accumulated agglomerates of the molten phase solidified on the furnace floor can stretch the lining material located in the horizontal grooves, which can lead to cooling elements move and create harmful cracks
In addition, cooling elements made of several pieces include many horizontal seams where harmful leaks can occur

Embodiment Construction
[0013] Figures 1a, 1b, 1c show a cooling element 1 according to the invention which is suitable for use eg in a wall structure of a flash smelting furnace. Figure 1a is a front view of the element, Figure 1b is a side view, and Figure 1c is a top view. The cooling element 1 comprises a copper housing 2 made of a single piece, in which is formed a channel system 3 for the circulation of a cooling medium. In addition, the cooling element comprises a sufficient amount of a lining 4 made of a refractory material such as chrome-magnesia brick, which is connected to the casing 2 . The shell and liner have elements for fastening them together. On the housing surface 8, vertical grooves 5 are formed, in which the individual liners 4 are placed one above the other in the vertical direction, so that in the vertical direction in the region where the cooling element comes into contact with the melt The entire slot is filled. The liner 4 and the casing 2 are connected so that the liner ...

Disclosed is a method for manufacturing a cooling element (1) to be used in the structure of a furnace used in metal processes, such as a flash smelting furnace, a blast furnace, an electric furnace or other metallurgical reactor, the cooling element having a copper housing (2) made of one single piece, in which housing there is formed a channel system (3) for the circulation of the cooling medium, lining elements (4) made of fireproof material, the housing and lining element including means for connecting them together, and the lining element (4) and the housing (2) are connected so that the lining element (4) can move in the vertical direction with respect to the housing (2). Also disclosed is a cooling element.
Description
technical field [0001] The invention relates to a method for producing a cooling element and to a cooling element. Background technique [0002] In industrial reactors, especially those used in metal processing, such as flash smelting furnaces, furnaces, electric furnaces, large and heavy cooling elements, usually made of copper, are used. Usually the cooling elements are water cooled and therefore provided with a cooling water channel system. In pyrometallurgical processes, the reactor brickwork is protected so that the heat directed to the surface of the brickwork is transferred to the water via cooling elements, in this case substantially less than in an uncooled reactor lining wear. The reduction in wear is achieved by a so-called "autogenous lining" solidified on the surface of the refractory lining, which is formed from slag and other substances separated from the molten phase. [0003] On the surface of the cooling element, there is usually a ceramic lining made, f...
