A taphole assembly () for arranging in a taphole assembly opening () extending through a shell () and a refractory lining () of a metallurgical furnace () such as a pyrometallurgical furnace and for leading melt from the inside of the metallurgical furnace () to the outside of the metallurgical furnace (). The taphole assembly comprises: a frame section of metal () to be arranged in a taphole assembly opening () extending through a shell () and a refractory lining () of a of a metallurgical furnace (), at least one refractory insert channel element () arranged in a seat () of the frame section of metal () and having a channel () for melt. The invention relates also to a method for manufacturing a taphole assembly and to a metallurgical furnace including a taphole assembly.

Taphole assembly, method for manufacturing a taphole assembly, and metallurgical furnace

The invention relates to a method for manufacturing a melt launder to be used for transferring molten phase such as slag, matte, or metal formed in a process for the production of metals. The invention also relates to a melt launder to be used for transferring molten phase such as slag, matte, or metal formed in a process for the production of metals. The melt launder comprises a launder body of metal, a flow channel for molten phase, a refractory lining for lining the launder body of metal so that the refractory lining at least partly forms a flow surface for molten phase in the flow channel for molten phase, and a layer of steel between the launder body of metal and the refractory lining.

Method for manufacturing a melt launder and a melt launder

A method for manufacturing a cooling element for a metallurgical furnace, wherein there is arranged a frame element mainly made of copper and provided with water cooling channels; in the frame element, there are arranged fastening elements for connecting refractory bricks to the frame element; and refractory bricks are connected to the frame element by using fastening elements; and wherein the fastening elements are at least partly formed of elongate steel fastening strips; the method comprising fastening the elongate fastening steel strips to the frame element so that the elongate fastening steel strips together form in between them an open interspace, which is narrowed in a direction pointed away from the bottom of the open interspace; and arranging refractory bricks in the open interspace so that the refractory bricks are located at least partly in the open interspace. A cooling element to be used in connection with a metallurgical furnace or the like is made mainly of copper and includes water cooling channels.

Method for manufacturing a cooling element and a cooling element

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.

Cooling element

The invention relates to an apparatus for mechanically breaking up and detaching dust accretions created by process gases and accumulated on the inner walls of a suspension smelting furnace and/or a waste heat boiler permanently connected to the suspension smelting furnace. According to the invention, on the outer surface ( ) of the wall of a suspension smelting furnace ( ) and/or a waste heat boiler ( ), in the vicinity of the connecting point ( ) of the suspension smelting furnace and the waste heat boiler, there is installed at least one striker device ( ), whereby there can be created a mechanical impact effect and mechanical contact between the apparatus ( ) and at least one of the dust accretions ( ).

Apparatus for removing dust accretions from a smelting furnace

The invention relates to a method of fabricating a pyrometallurgical reactor cooling element with flow channels. In order to enhance heat transfer capability, the wall surface area of the flow channel, which is traditionally round in cross-section, is increased without increasing the diameter or length of the channel.
