Abstract
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.
Claims18
A method for manufacturing a cooling element to be used in the structure of a flash smelting furnace, a blast furnace, an electric furnace or other metallurgical reactor, said cooling element comprising a copper housing made of one single piece, in which housing there is formed a channel system for circulation of cooling medium, one or more lining elements made of fireproof material, the method comprising connecting the one or more lining elements and the housing so that the one or more lining elements are movable in the vertical direction with respect to the housing in response to thermal expansion during operation of said furnace or reactor.
A cooling element to be used in the structure of a flash smelting furnace, a blast furnace, an electric furnace or other metallurgical reactor, said cooling element comprising a copper housing made of one single piece, in which housing there is formed a channel system for circulation of cooling medium, and further comprising one or more lining elements made of fireproof material, said housing and one or more lining elements being connected together, and the one or more lining elements and the housing being connected so that the one or more lining elements are movable in the vertical direction with respect to the housing in response to thermal expansion during operation of said furnace or reactor.
