Definitions
- the invention relates to a method for constructing a metallurgical furnace having a wall structure limiting a vertical furnace section of a furnace space of a metallurgical furnace as defined in the preamble of independent claim 1.
- the invention also relates to a metallurgical furnace having a wall structure limiting a vertical furnace section of a furnace space of a metallurgical furnace as defined in the preamble of independent claim 18.
- the invention relates also to a vertical cooling element for use in the method or in the wall structure.
- WO 2006/040393 presents a metallurgical furnace comprising a wall that has an external steel structure, cooling elements and a refractory block lining inside the steel structure.
- Metallurgical furnaces comprising a wall having such construction has some disadvantages. Firstly, assembly of the metallurgical furnace wall is done so that the mantle is firstly installed and cooling elements and refractory blocks are installed from the furnace space of the metallurgical furnace. This is time consuming since material and installation personnel need to be located in the furnace space. Secondly going into the furnace space for maintenance provides that an opening must be cut thorough the external steel structure and the cooling elements and the refractory bricks must be removed.
- the furnace structure integrity is very much dependent on how much the external steel structure can sustain before failing.
- the expansion allowance in the external steel structure is basically the amount of deformation the mantle can tolerate before plastic deformation and rupture.
- the object of the invention is to provide a method for constructing a wall structure limiting a vertical furnace section of a furnace space of a metallurgical furnace, a wall structure limiting a vertical furnace section of a furnace space of a metallurgical furnace, and a vertical cooling element for use in the method or in the wall structure, which provide a solution to the mentioned disadvantages.
- the metallurgical furnace of the invention is correspondingly characterized by the definitions of independent claim 18.
- Preferred embodiments of the metallurgical furnace are defined in the dependent claims 19 to 34.
- the vertical cooling element for use in the method or in the metallurgical furnace is presented in claim 35.
- the invention provides for several advantages. Assembly of the metallurgical furnace is faster as the vertical cooling elements of the wall structure can be installed from outside and are joined together by means of vertical flanges of the vertical cooling elements from the outside of the furnace. This allows work to proceed inside the furnace space of the metallurgical furnace without further disturbance.
- a maintenance opening can easily be made by opening external fastening means connecting vertical cooling elements together and by subsequently removing at least one vertical cooling element.
- the reassembly can easily be done in the opposite order.
- suitable expansion allowance can be designed into the vertical cooling element layer. This allowance can easily be modified before or during operation, in opposite to the structure presented in publication WO 2006/040394.
