Definitions

  • the invention relates to cooling plates preferably made of copper or a low-alloy Copper alloy, (so-called "Staves”), for with a refractory lining
  • a refractory lining Provided shaft furnaces, in particular blast furnaces, with one Coolant can be acted upon by coolant channels, at least the inside of the furnace facing front grooves for receiving and holding refractory Has material.
  • the cooling channels are forged or rolled ingot as vertical blind holes, which are introduced through deep mechanical drilling.
  • such Cooling plates must have a relatively large thickness so that the Cooling channels still have enough wall thickness to the operating pressure of the To be able to absorb coolant.
  • Copper plates of the required Thicknesses are expensive because of the high copper price.
  • the blind holes have only the smallest possible inner surface with a circular cross-section on. As a result, there is little to the heat exchange with the coolant Space available, only moderate heat dissipation is achieved. This causes high thermal stresses on the cooling plate and influences it Service life disadvantageous.
  • Cooling plates for electric arc furnaces are known from US-A-4,342,118 become, which consist of two corrugated metal profiles, the wave crests of a thinner profile with the troughs of the opposite thicker profile are welded. This creates a relatively large one Cooling plate in which a coolant channel meanders. In the troughs the thicker profiles have a large number of metal bars arranged which serve to adhere fireproof spray compounds. With such a big one As a rule, the cooling plates can be essentially flat poorly line the curved interior of ovens. On top of that the metal rods for holding the fireclay on the plates are complex and expensive need to be welded on and even bad to hold the Chamotte contribute.
  • US-A-5,426,664 also discloses cooling plates for electric arc furnaces, which consists of a copper sheet adapted to the bend of the furnace welded on the back of a plurality of cooling channels containing sheet metal strips is. This is also a large extension cooling plate due to their specified curvature only for ovens with a specific one Diameter can be used. There is no universal applicability.
  • This cooling plate also has a large number of blocks placed on it to prevent the fireclay attached to the inner wall from the The cooling plate slips off.
  • the invention is therefore based on the object of cooling plates of the generic type Type in such a way that they with less material and manufacturing costs to manufacture and easier to assemble than the previously known, and that with them higher cooling capacities with lower coolant throughput can be provided, the self-heating is so limited that much longer downtimes can be achieved.
  • the cooling plates according to the invention can be installed in such a way that the edge areas of the cooling channel lying to the side are adjacent Overlap the cooling plates.
  • Figure 1 is a cross section of a cooling plate placed in the middle of the length shown, which shows a corrugated rolled profile 1 turned towards the inside of the furnace, which Copper or a copper alloy.
  • this rolled section 1 in the form of a shield are rolled into the free surface transverse groove 4 with the Complete the installation by applying refractory ramming or spraying compounds easier, and which later favor the adhesion of Möller components.
  • This supplementary rolled section 3 is also trough-shaped and narrower than the other rolled section 1 and extends between approximately straight edge areas of the rolled section 1. It also contains essential parts of it Length of a web extending vertically from its center 5, which on the one hand increases the stability of the entire cooling plate, and on the other hand their assembly easier.
  • a bracket 8 is attached to the inner wall 9 of the shaft furnace, welded in the embodiment, which is provided with holes 6.
  • the actual connection is made by inserting it and securing the bolt 7 in the bores 6, 6 '.
  • the cooling plate can be cast with the backfill 10 and then, in not shown in Figure 1, the surface of the shield 1 of the cooling plate a refractory ramming or spraying compound.
  • Figure 2 also shows a cross section through the cooling plate, but in its End.
  • the two rolled sections 1 and 3 again shown, which are firmly and tightly connected by welds 13.
  • a pipe fitting 12 inserted and fixed with the rolled profile 3 and tightly connected by a weld 14.
  • the cooling plate is not used individually, it is intended as a module, that can be assembled into larger cooling surfaces.
  • the assembly of the Cooling elements take place in such a way that the side of the cooling channel lying edge area of a cooling plate, which is only one element of the cooling surface represents the corresponding edge area of the adjacent cooling plate overlaps. In this way, even in conical parts of a furnace, for example, rest, shaft or the like, a balance of the different Diameter or circumferences of the tank take place without the width dimensions of the cooling plate adapted to the cone shape Need to become.
  • the welding of the rolled section 1 with the additional rolled section 3 to the cooling plate or to the modular cooling element is preferably carried out continuously on one appropriate welding machines, so that a uniform, error-free and liquid-tight design of the weld is guaranteed. While out Thermal conductivity reasons the rolled section 1 made of copper or a copper-rich alloy is manufactured, cheaper materials can also be used for the supplementary rolled section 3 be, which may have the advantage of higher strength. It is only essential that the two rolled sections 1 and 2 weld well and easily to let.
