Definitions
- the invention relates to cooling plates (so-called “staves”) for shaft furnaces provided with a refractory lining, in particular blast furnaces, with cooling passages which can be acted upon by a coolant, at least the front side facing the furnace interior having a groove, preferably made of copper, for receiving refractory material or a low-alloyed copper alloy billet.
- the cooling channels in a forged or rolled ingot are provided as vertically running blind bores which are introduced through mechanical deep bores.
- Such cooling plates must have a relatively large thickness so that the cooling channels still have sufficient wall thickness to be able to absorb the operating pressure of the coolant.
- Copper plates of the required thickness are expensive because of the high copper price.
- the blind holes With a circular cross-section, the blind holes only have the smallest possible inner surface. As a result, there is only a small area available for heat exchange with the coolant, and only moderate heat dissipation is achieved. This causes high thermal stresses on the cooling plate and adversely affects its service life.
- the invention is therefore based on the object of designing cooling plates of the generic type in such a way that they can be produced with less material and production outlay and are easier to assemble than the previously known, and that they can be used to achieve higher cooling capacities with a lower coolant throughput, the self-heating being so limited that considerably longer service lives can be achieved.
- the front part of the cooling plate is trough-shaped in the middle region as a curved rolling part of relatively low thickness, so that considerable copper savings occur, and the curvature by means of a second rolling part, which is also curved outwards, to form a cooling channel with a cross section deviating from the circular shape and thus to add higher cooling capacity.
- the advantage of low copper consumption is the advantage of intensive cooling, which extends the service life as desired.
- Figure 3 shows a double interrupted longitudinal section through one in a
- Figure 4 is the rear view of the cooling plate.
- FIG. 1 shows a cross section of a cooling plate, which is placed in the middle of the length and shows a shield 1 turned towards the inside of the furnace, which is rolled out of copper or a copper alloy in a trough shape.
- this sign 1 are rolled into the free surface transverse groove 4, which facilitate the application of refractory ramming or spraying compounds at the end of the assembly, and which later favor the adhesion of Möller components.
- a supplementary profile 3 is connected to the shield 1 by weld seams 13.
- This supplementary profile is also trough-shaped; However, over substantial parts of its length, it also contains a web 5 which extends vertically from the center thereof and which on the one hand increases the stability of the entire cooling plate and on the other hand facilitates its assembly.
- a bracket 8 is attached to the inner wall 9 of the shaft furnace, welded in the exemplary embodiment, which is provided with holes 6.
- the actual connection is made by inserting and securing the bolt 7 into the bores 6, 6 '.
- the cooling plate can then be cast with the backfilling compound 10 and then, not shown in FIG. 1, the surface of the shield 1 of the cooling plate can be covered with a refractory ramming or spray compound.
- Figure 2 also shows a cross section through the cooling plate, but in its end region.
- the shield 1 and the supplementary profile 3 are shown, which are firmly and tightly connected to one another by weld seams 13.
- One end of a pipe connection piece 12 is inserted into a bore provided in the supplementary profile 3 and firmly and tightly connected to the supplementary profile by a weld seam 14.
- the cooling plate is not used individually, it is intended as a module that can be combined into larger cooling surfaces.
- the cooling elements are installed in such a way that the side of the cooling channel lying front parts of the cooling plate, which here is only one element of the cooling surface, overlap with the corresponding parts of the adjacent cooling plate. In this way, the different diameters or circumferences of the shell can also be compensated for in conical parts of a blast furnace shell, for example a rest, shaft or the like, without the width dimensions of the cooling plate having to be adapted to the cone shape.
- the welding of the shield 1 with the supplementary profile 3 to the cooling plate or to the modular cooling element is preferably carried out continuously on an appropriate welding machine, so that a uniform, error-free and liquid-tight design of the weld seam is ensured.
- the shield 1 is made of copper or a copper-rich alloy for thermal conductivity reasons, cheaper materials can also be used for the supplementary profile 3, which may have the advantage of higher strength. It is only important that the shield 1 and supplementary profile 3 can be welded well and easily.
