A method for coating the base element of a cooling element used in connection with a metallurgical furnace or the like, said base element being mainly made of copper, at least partly with a metal coating involves a step wherein the metal coating is explosion welded to the base element of a cooling element mainly made of copper. A cooling element, particularly to be used in connection with metallurgical furnaces or the like, includes a base element mainly made of copper, in which base element there is arranged a cooling water channel system, said base element of the cooling element being at least partly coated with a metal coating. The metal coating is explosion welded to the base element that is mainly made of copper.

Method for manufacturing a cooling element and a cooling element

The invention relates to a cooling element to be used in the structure of a pyromettalurgical reactor used in the manufacturing of metals, which cooling element comprises a housing element mainly made of copper, provided with a channel system for the cooling medium circulation, made of pipe that is mainly made of copper; on the outer surface of the pipes forming the channel system, there is arranged a coating that has a lower melting point than the material of the housing element and the pipe. The invention also relates to a method for manufacturing the cooling element.

Cooling element and method for manufacturing the same

Disclosed is a method for manufacturing a cooling element () 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 () made of one single piece, in which housing there is formed a channel system () for the circulation of the cooling medium, lining elements () made of fireproof material, the housing and lining element including means for connecting them together, and the lining element () and the housing () are connected so that the lining element () can move in the vertical direction with respect to the housing (). Also disclosed is a cooling element.
