Definitions
- the invention relates to a process container with cooling elements and with at least one applied on the inside of a metallic container shell refractory lining layer, each cooling element consists of a base plate and at least one heat-conducting connected thereto cooling channel, the ends of each of which a connection arrangement for the connection to the Have cooling channel of an adjacent cooling element.
- the refractory linings of metallurgical containers must be resistant to the action of liquid melts and slags and also have an insulating effect, so that the container jacket remains cool enough and thus sufficiently stable. The often considerable wear of the linings can be reduced by their cooling.
- cooling elements For electric melting furnaces cooling elements are known which form a substantial static component of the container wall construction, by relatively large, rigid plate elements and are in firm association with the applied directly on its inside refractory lining layer. Examples of such cooling elements can be found in US 3,314,668, US 4,221,922, O02 / 27042 or WO 02/081757. The dimensions of such a cooling element are, for example, 1.71 m ⁇ 6.10 m, and the thickness of its base plate 16 mm, according to the specifications of said US Pat. No. 4,221,922.
- the invention has for its object to find a process container of the type mentioned, which can be produced with relatively little effort and thus cost by Nachrusten an existing Rothbehalters and by reducing the wear of its refractory lining a longer operation until the next Repair of the lining allows.
- the metallic Behaltermantel a metallurgical Sawbehalters will differ in any case from the theoretically ideal shape eg cylindrical shape.
- the imperfections of the unloaded, new component are usually still quite small. But if the container jacket is heated by the process heat, it expands. Since the jacket temperature is not uniform due to different heat supply and / or removal, for example due to unilateral curling by wind or by deposition of dust on individual zones, the strains are different over the circumference.
- the mantle will inevitably deviate from the theoretical eg cylindrical shape. Localized bulges or indentations can become particularly large if limited damage to the refractory lining results in severe localized overheating.
- the cooling device described with reference to the embodiment is suitable for adapting to such changes in shape and thereby withstanding the high surface temperatures of, for example, a reflow furnace for lead refining.
- FIG. 1 shows a radial section through a region of a container jacket equipped with cooling elements according to FIG.
- FIG. 2 shows a complete plan view of a cooling element and a partial representation of two adjacent, similar, incompletely shown cooling elements.
- the standing or lying arranged, for example, cylindrical process container 1 has a molded steel container shell 2, which is protected against a highly heated container contents, such as a molten metal th by refractory lining layers 3.4.
- a highly heated container contents such as a molten metal th by refractory lining layers 3.4.
- a plurality of identically designed cooling elements 5, 5 ', 5 attached to the outside of the container shell 2 .
- Each cooling element 5, 5 ', 5 ", of which on a process container 1 with a diameter of, for example, 3 m and a length of, for example, 25 m both in the circumferential direction and in the longitudinal direction, for example, twenty each are arranged side by side consists essentially of a relatively thin and thus flexible base plate 6, with a thickness of less than 5 mm and preferably 3 or 4 mm and at least one, with this heat-conducting connected cooling channel. 7
- the cooling channel 7 extends with several, for example, three courses 8,9,10 and connecting 180 ° curvatures serpentine or serpentine curved along the outer surface of the base plate 6 facing away from the container shell 2 over as large a part of its surface as possible large surface to be in heat-conducting contact.
- He has, for example, the shell-shaped cross-sectional shape of a half-cut tube, which is welded along its cross-sectional ends with the base plate 6, so that the base plate 6 forms part of the channel cross-section.
- other cross-sectional shapes may be chosen, examples of which are known by the aforementioned US 4,221,922.
- connection arrangement which extends from one of the cooling element 5, 5 ', 5" or from the process container 1 consists of an externally directed, curved connecting piece 13,14 with an end flange 15,16 and a one of the connecting pieces 13,14 of adjacent cooling elements 5, 5 ', 5 "connecting end flanges 17,18 having compensation tube 19. It has a corrugated tube portion 20, so that it can compensate for inaccuracies of the association between adjacentdeele ' elements 5, 5', 5 "and thermal expansion in the container shell 2.
- Base plate 6 extend at corresponding positions provided bolt holes 22 and are also provided along the edges 27,28 of the base plate 6 in a gap between adjacent Kuhlelementen 5, 5 ', 5 “A respectively staggered on them Druckstuck 23, which is considerably wider than that Bolt holes 22 and a plate spring 24 are clamped by a nut 25, so that each base plate 6 is printed with elastic bias at numerous points corresponding to the size of the Druckstuckes 23 against Behaltermantel 2 and conforms by bending deformation to the surface shape of Behaltermantels 2.
- the base plate 6 ensures a good adaptation to irregularities of the surface of Behaltermantels 2, which are production-related and also result from the heating of the Prozeßbehalters and its charging, so that was a more extensive eubertragender contact the Kuhletti 5, 5 ', 5 "with Behalterm antel 2 is guaranteed.
- the plastic deformability of the heat-insulating paste ensures an adaptation on shape or large changes in the filled column as a result of said, resulting in the operation of the process container relative deformations between the base plate 6 and the Behalterwand 2. This also contributes to the elastic bias of the screw fastening, which achieved by said plate springs 24 becomes.
- threaded holes 25 are provided in several places in the base plate 6, in which the nipple of a paste press can be connected.
- thermosetting Warmeleitpaste 30,31 which is applied externally along the edges of the base plate 6 and thereby also the gap 31 between adjacent cooling elements 5, 5 ', 5 "can fill .
- the sealing along the edges of the base plate 6 also allows the use of a less viscous and in terms of their heat conduction optimized Warmeiteitpaste between the container shell 2 and the base plate 6 of the cooling elements 5, 5 ', 5 ".
