Definitions

  • the invention relates to one with a refractory lining and an outer furnace sheet metal metallurgical furnace, such as Blast furnace, smelting or smelting reduction furnace with a copper cooling plate by a coolant flows between the furnace sheet and the refractory lining is arranged, wherein the coolant tubes of the copper cooling plate for feeding and discharging the coolant through the furnace sheet to the outside and are welded gas-tight to the furnace shell.
  • Copper cooling plates made of copper or a low-alloy Copper alloy with coolant channels arranged in its interior by rolling, forging or casting, normally have four coolant tubes on the top and four coolant tubes on the bottom, where however, there may also be fewer or more coolant tubes, accordingly the number of available coolant channels.
  • cooling plates are proposed in US-A-5,904,893 to be provided with a recess in which a support pin of the blast furnace shell intervenes and thus hang up on the stove.
  • the cooling plate is also suspended from the furnace shell attached, the cooling plates have hooks that are welded to the furnace shell Engage the hook.
  • the hooks of the cooling plate can be used for better Positioning of the cooling plate can be designed as a rail.
  • cooling plate is provided with a thread that runs through the furnace shell is, whereby the cooling plate is attached to the furnace by screwing can be.
  • cooling plates made of cast iron are known to be attached to the furnace shell of a blast furnace with screws that are provided on the outside with a sealing hood. Disadvantage with this type of attachment is that with high heat loads on the cooling plates, these fastening screws expand and the cooling plates towards the center of the oven can move, causing hot furnace gas through the gap between the Cooling plates and the furnace shell flow and the furnace paris uncontrolled heated.
  • DE 31 00 321 C1 therefore proposes protective tubes in the cooling plates pour in the coolant pipes in the area of the furnace armored penetrations surrounded by a distance, the openings in the furnace shell are sealed against leakage of the furnace gases and at least one these protective tubes by welding them to the furnace shell as a fixed bearing serves and other protective tubes lying on the same level as horizontally displaceable Bearings are formed. Furthermore, at least one of these the protective tube opposite the protective tube serving as a fixed bearing as vertical slidable storage and are the other lying on this level Protection tubes designed as a floating bearing.
  • Each coolant tube is over one Disk connected to a metal compensator by a protective housing is surrounded and gas-tight directly or via a pipe socket on the furnace shell is welded to the mounting point of the cooling plate by means of Sealing protective tubes against undesired furnace gas leakage.
  • Coolant pipes passed through holes in the furnace shell and by means of one a welded expansion joint on the one hand and by means of a Welding point between the compensator and the coolant pipe, on the other hand, is elastic connected to the furnace.
  • the task is in a metallurgical furnace with copper cooling plates of the aforementioned Kind according to the characterizing features of claim 1 solved in that the copper cooling plates in addition to the fastening with the with the furnace armor plate welded coolant pipes through at least one to the furnace shell welded fixed point fastener, for example a fastening bolt, with which the hearthplate is connected without play in all spatial directions.
  • the invention two basic fastening variants are conceivable, depending on the size of the copper cooling plate and the number of coolant channels or Coolant pipes can be used.
  • the copper cooling plate for example, it is possible to attach the copper cooling plate to a fastening bolt or to hang on another fastener, the in close proximity to the upper and / or lower coolant pipes through the oven armor.
  • the fastener is connected to the furnace armor and the copper cooling plate, that the fastener as a fixed point in all spatial directions acts.
  • the immediate proximity of the fastener to the coolant tubes on the one hand and the very low thermal expansion of the copper on the other cause the due to temperature fluctuations expected thermal expansion relative between the fastener and the neighboring coolant pipes are so small that the compensators on these coolant tubes can be dispensed with.
  • the Coolant pipes can therefore directly, i. H.
  • the remaining coolant pipes are, as usual, with compensators on the furnace armor plate attached and thus represent ticket points in all spatial directions.
  • the copper cooling plate is also at other lot points by means of appropriate Fastening elements, for example screws, with the furnace shell connected by the movements due to thermal expansion in the vertical / horizontal direction are possible.
  • Another variant for attaching a copper cooling plate is the copper cooling plate with at least one fixed point fastening element - approximately in the middle of the copper cooling plate.
  • the copper cooling plate, with additional loose point fasteners can then completely are welded to the furnace shell without compensators, all of them Coolant pipes then act as further fixed points.
  • the expected thermal Extentions between the fixed points available in this way are so small that they can be neglected and therefore none Compensators are needed more.
  • the elimination of the compensators poses a considerable amount due to the reduced assembly and welding effort Advantage, because a compensator on the one hand on the furnace sheet and on the other be welded gas-tight on the pipe socket of the copper cooling plate would.
  • the attachment of the copper cooling plate according to the invention can accordingly Copper cooling plates in metallurgical furnaces, in particular blast furnaces or other smelting and smelting reduction furnaces thus easier, faster and can be assembled more cheaply.
  • FIG. 1 and 2 is a plan view (Fig. 1) and a side view (Fig. 2) a copper cooling plate 10 shown with four coolant channels (not visible), the coolant tubes 13, 14 for supplying and removing the coolant arranged on the upper and lower part of the copper cooling plate 10 are.
  • a fixed point fastening element 11 In the immediate vicinity of the upper coolant tubes 13 is a fixed point fastening element 11 a fastening bolt arranged with a Disk 17 is welded to the furnace armor plate 15.
  • the inventive attachment of the copper cooling plate 10 on the Furnace armor plate 15 are forces due to thermal expansion easily recorded, with the upper coolant tubes 13 and the fastening bolts 11 as fixed points, the lower coolant tubes 14 with compensators 16 in all spatial directions as loose points and the fastening screws 12 also act as lot points in the vertical / horizontal direction.
  • FIG. 3 and 4 is a plan view (Fig. 3) and a side view (Fig. 4) another type of attachment or embodiment of a copper cooling plate 10 'in connection with the furnace sheet 15 according to the invention shown.
  • further starting point fastening elements 12 fastening screws
  • all expansion joints can be dispensed with because of the thermal expansion relative between the fixed point fasteners and the Fixed positions of the upper and also the lower coolant tubes 13 so low are that these can be neglected.
  • the attachment of the copper cooling plate 10 'therefore consists in this variant of the fixed points of Fastening bolt 11 and the welded coolant tubes 13, 14 and the loose points (in the vertical / horizontal direction) of the fastening screws 12th
  • the invention is not restricted to the exemplary embodiments shown, especially with regard to the number and arrangement of the fixed point and Lostician fasteners and their training as bolts or screws are appropriate depending on the size of the copper cooling plates Variations possible if this eliminates compensators in the sense the invention is made possible.
