Definitions
- the invention relates to a cooling plate for shaft furnaces provided with a refractory lining, in particular for blast furnaces, with a first rolled cooling plate part pointing towards the inside of the furnace and a second rolled rear cooling plate part which are welded to one another, and with a cooling box which is formed between the first and the second cooling plate parts - nal and with pipe sections for coolant inlet or outlet.
- Both the first and the second cooling plate parts consist of copper or a low-alloy copper alloy.
- the invention also relates to a cooling system.
- a generic cooling plate is described in German patent application 100 00 987.5. This discloses a cooling plate for shaft furnaces provided with a refractory lining, with cooling channels that can be acted upon by a coolant, at least the front side facing the furnace interior consisting of a rolling block equipped with grooves for receiving refractory material, preferably made of copper or a low-alloy copper alloy, wherein two trough-shaped rolled profiles are welded to each other with their troughs facing each other and wherein holes are made in the rear rolled profile or supplementary profile for receiving the ends of pipe fittings and these are welded in and the free ends of the rolled profiles are closed by caps.
- the bending of the first cooling plate part or shield as well as the introduction of grooves in the curved shield is complex in terms of production technology.
- the roughly "lenticular" cross section of the cooling channel which results from the trough shape of the two cooling plate parts, proves to be unfavorable from a flow point of view. While that from the lateral fins of the shield to the cooling water flow of heat is greatest in the corners of the "lens", the flow rate of the cooling water is the lowest.
- the low flow rate leads to a low heat transfer coefficient ⁇ from the inside of the cooling channel to the cooling water.
- the invention is therefore based on the object of creating a generic cooling plate with improved manufacturing, flow and cooling properties.
- the first cooling plate part or the shield of the cooling plate or the stavelet is no longer curved, but is designed as a rolling block with a flat front to the inside of the furnace, ie with a flat hot side, and the cross-sectional area between the the first and the second cooling plate part resulting cooling channel is - in relation to the longitudinal extent of the cross-sectional area - the end regions larger than in the central region.
- End regions of the cooling duct cross section are the regions in the vicinity of the connecting lines or weld seams of the two cooling plate parts.
- the end regions can have any shape as long as they have a larger cross-sectional area than the central region.
- This cross-sectional shape according to the invention has the effect that the major part of the cooling water no longer flows in the central region, but rather in the heat-stressed end regions of the cooling channel, with larger flow velocities and thus more favorable heat transfer coefficient values being achieved.
- the cross-section in the middle area is to be designed in such a ratio that the heat generated there can be dissipated well.
- a cooling plate with improved flow properties of the cooling water and thus cooling properties is created in this way.
- the temperature on the hot side, ie the side facing the interior of the furnace, is evened out.
- the introduction of grooves in a flat cooling plate can be made much easier than in a curved one, for example by milling or by profile rolling.
- the end regions of the cooling duct cross section are curved on one side or on both sides. Taking into account the central area, a cooling channel cross section results that is roughly comparable to the shape of a bone or a half bone cut in its longitudinal axis. This shape ensures a particularly good ratio of the flow rate of the cooling water to the heat loads.
- a first cooling plate part with recesses made in its water-side rear side is used, or a double trough-shaped second cooling plate part shaped with bulges pointing towards the furnace wall.
- a first cooling plate part is combined with an approximately planar second cooling plate part;
- a trough-shaped second cooling plate part is combined with a first cooling plate part with a flat water-side back.
- a first cooling plate part with depressions is combined with a corresponding second cooling plate part with depressions or with a double trough-shaped second cooling plate part.
- the depressions, which preferably run parallel to the longitudinal axis of the cooling plate are introduced by profile rolling or by milling.
- the trough-shaped second cooling plate part which is thinner than the first cooling plate part, is produced by profile rolling or bending.
- Both the first and the second cooling plate part consist of copper or a copper alloy.
- the trough-shaped second cooling plate part has a different material thickness over its width. It is thicker at the edges than in its central area. This has the advantage that in the area of increased heat flow, i.e. in the edge area, more copper material and thus more material for heat conduction is available. Due to the reinforced edge areas, the weld seam for connecting the two parts can also be made more solid. This contributes to the mechanical stability of the cooling plate and thus also to the further improvement of the cooling characteristics.
- a second cooling plate part can be welded to the edges of the first cooling plate part. According to a preferred embodiment, it is welded to the back of the first cooling plate part with its longitudinal edges bent towards the rear of the first cooling plate part in the sense of a supplementary profile. In order to prevent the edges of the first cooling plate part from becoming wavy due to an uneven temperature distribution, it is proposed to make slots at regular intervals in the edge regions of the first cooling plate part perpendicular to the longitudinal axis of the cooling plate.
- the free ends of the two interconnected cooling plate parts are closed with caps, and the pipe sections for the coolant inlet and outlet protrude through holes in the rear second cooling plate part.
- the first cooling plate part which is provided with cooling channel depressions, hollowed out at the height of the pipe sections, for example by milling away the copper.
- a transition of the enlarged entry or exit area to the cooling channel depressions is achieved in that the depth of the cavity decreases like a ramp towards the cooling channel depressions.
- the reason for the lower pressure losses is a softer transition from the round pipe section to the cooling channel cross section proposed according to the invention with larger end regions and a small central region.
- the cooling plate has at least two suspension points, with a first suspension point as a fixed connection in the upper part of the cooling plate, preferably above the pipe section for the coolant inlet or outlet , is formed and a second suspension point is formed as a loose connection in the lower part of the cooling plate, preferably just above the pipe section for the coolant inlet or outlet.
- This advantageous suspension with loose points which are preferably designed as a suspension, ensures that the lower part of the cooling plate can thermally expand.
- FIG. 1 shows a cross section of a cooling plate according to a first embodiment.
- FIG. 2 shows a cross section of a cooling plate according to a second embodiment
- FIG. 3 shows a preferably designed second cooling plate part according to FIG. 2
- 4 shows a longitudinal section of a cooling plate mounted on a shaft furnace wall
- FIG. 5 shows a partial section of a longitudinal section of a preferably designed first cooling plate part according to FIG. 1;
- FIG. 6 shows a side view of a cooling plate with a preferably formed first cooling plate part
- FIG. 7 shows a detail of a cooling system mounted on a furnace wall
- FIG. 8 shows the longitudinal section A-A of a cooling plate according to FIG. 7;
- FIG. 9 shows the upper partial section shown in FIG. 8 in an enlarged manner
- Fig. 10 shows the lower partial sections shown in Fig. 8 in an enlarged view.
- FIG. 1 shows a cooling plate 1 or a stavelet with a first cooling plate part 2, which faces the interior of the oven Oj, and a second rear cooling plate part 3, which are welded together.
- the weld seams 4 lie on the protected, cold side of the cooling plate or the stavelet.
- the cooling channel 7 Between the water-side back 5 of the first cooling plate part 2 as a rolled copper block 5 and the water-side 6 of the second cooling plate part 3 there is the cooling channel 7, which is fed with a cooling medium, preferably cooling water.
- Pipe sections 8, 9 are mounted in bores in the second cooling plate part 3 for the water inlet and outlet.
- the cooling plate 1 is fastened to the furnace wall 10, for example, by means of a web 11 which is inserted into a holder 12 which is mounted on the furnace wall and is locked by means of a bolt 13 (cf. FIG. 4).
- the first cooling plate part 2 is designed as a solid roll block with a flat - in the sense of non-curved - front side 14, into which grooves 15 are made which run transversely to the longitudinal axis of the cooling plate 1 and which facilitate the application of refractory 5 ramming or spraying compounds when the assembly is complete , In the water-side rear side 5 of the first cooling plate part 2 or shield, two recesses 16, 17, which run parallel to the longitudinal axis of the plate 1, are made, each of which has an approximately semicircular cross section.
- the cooling duct 7 is closed at the rear, ie facing the furnace wall, with a second cooling plate part 3, which is approximately planar or slightly curved outwards, in the sense of a supplementary part.
- the result is a cooling channel 7 with a cross-sectional area, the end regions 18, 19, as viewed in relation to the longitudinal extent (x direction), having a larger cross-sectional area than the central region 20.
- FIG. 2 Another preferred embodiment of a cooling plate 101 with a claimed cooling channel cross section is shown in FIG. 2.
- the desired cross section of the channel 107 - here the cross section perpendicular to the longitudinal axis of the cooling plate - is determined by the shape of the second cooling plate part 103. It is shaped like a double trough. Through the curvature of the troughs 121, 122 and the formation of a - here - short or even longer central region 123, the desired cooling channel cross section with larger Ehd areas 118, 119 is created in comparison to the central region 120 of the cross section.
- the trough-shaped second cooling plate part 203 or the copper sheet is reinforced at its edge regions 324, 325, i.e. formed thicker, as shown in Fig. 3. This is possible, for example, using profile rollers.
- Fig. 4 shows the longitudinal section of a cooling plate 1 in the fastening position on the furnace wall, for example the wall of a blast furnace.
- the pipe sections 8 and 9 are welded to the second cooling plate part 3 (27).
- the cooling channel 7 is closed at the free ends by means of caps 28, 29.
- a further preferred embodiment of the cooling plate 1, starting from the embodiment according to FIG. 1, is shown with FIG. 5.
- the solidly designed first cooling plate part 1 is hollowed out further in the areas opposite the pipe sections 8, 9 for the water inlet or outlet (hollows 30), so that the inlet or outlet area is enlarged. This cross-sectional enlargement is slowly - ramp-like - adapted to the course of the cooling channel depressions 16, 17. This has a positive effect on reducing cooling water pressure losses.
- the second cooling plate part 3 is attached to the back of the first cooling plate part 2 in such a way that the edge regions 2a, b (or fin regions) are not covered, there is a risk of the first cooling plate part becoming wavy. This is prevented by introducing slots 31 into the edge regions 2a, b transversely to the longitudinal axis of the cooling plate, which extend from the edge region 32 to approximately the second cooling plate part 3. Due to the slots, the edge areas can expand thermally without stress when used.
- the cooling plates according to the invention are assembled into cooling systems. For example, they are arranged directly next to one another, and their stability can be supported by a tongue and groove principle in the first cooling plate parts. Alternatively, the edge areas of the first cooling plate parts can also be arranged in an overlapping manner.
- FIG. 7 shows a section of such a cooling system 33 comprising a plurality of cooling plates 1 or stavelets, which also shows a further preferred suspension system for the stavelets on the furnace wall 10.
- each cooling plate 1 or each stavelet has a plurality of suspension points 34-39, here in each case six, the upper suspension points 34, 35 being designed as fixed points and the suspension points 36-39 below them being designed as loose points.
- the fixed points 34, 35 (cf. FIG. 8 and in particular FIG. 9), a fixed connection between the cooling plate 1 and the furnace wall 10 is established by screwing in a screw 40 from above.
- a projection 41 is provided on the furnace wall 10 and a corresponding projection 42 on the rear of the cooling plate 1 outside the cooling channel region - preferably by welding - which have corresponding bores and which are connected to one another via the screw 40.
- Loose points 36-39 are comparable to a door suspension, as can be seen in detail in FIG. 10.
- the cooling plate in turn has corresponding projections 43 on its rear side which are provided with a bore and which are suspended in pins 44 protruding from the furnace wall, held by a projection 45.
- These loose points 36-39 allow thermal expansion of the cooling plate 1 downwards. So that the space required for the expansion on the suspensions or loose points is not blocked by backfill, a lost part 46 made of plastic, preferably styrofoam, is used at this point during assembly.
- the proposed cooling channel cross section results in a fluidically and cooling-technically optimized stavelet, which also has manufacturing advantages over the known stavelet. Compared to the known Cu staves, these stavelets achieve high material and weight savings due to their smaller thickness, which is also associated with a larger usable volume of the furnace area.
