Definitions

  • the invention relates to a cooling plate with reinforced head ends for with one refractory lining shaft furnaces, in particular blast furnaces consisting of copper or one low-alloy copper alloy with inside arranged coolant channels, the cooling plate from a forged or rolled ingot is made, the cooling channels running vertically Are blind holes and being on the inside of the Shaft furnace facing side ridges and grooves incorporated are.
  • Such cooling plates are usually between the Furnace jacket and the furnace lining arranged and on the cooling system of the shaft furnace is connected. On the the cooling elements are on the inside of the furnace partly provided with fireproof material.
  • a cooling plate is known from DE 39 25 280, at which the cooling channels through pipes cast in cast iron are formed and the lower edge of the plate body trained as a support nose for the fireproof masonry is.
  • the support nose is also connected to the cooling system connected.
  • a cooling plate is known from a forged or rolled ingot is made and where the cooling channels run vertically Blind holes are, which by mechanical Deep drilling are introduced.
  • the structure of the cooling plate is much denser and more homogeneous than one Cast copper plate; Blowholes, such as those found in cast copper plates occur frequently are excluded.
  • the strength values lie higher and the thermal conductivity is more uniform and higher than that of the cast copper plates.
  • the target position of the holes according to height and side is strictly adhered to and thus an even one Guaranteed heat dissipation.
  • the cooling plate faces the inside of the furnace Side with refractory bricks or with a refractory Rammed earth lined. This will make the cooling surface the plate downsized and in case of wear or the loss of the refractory furnace lining heat removal from the oven is limited. Furthermore, the cooling of the plate should be so intense that the temperature of the hot plate side is well below the softening temperature of copper is maintained.
  • From DE-OS 23 62 974 is a cooled shaft furnace known with a steel jacket, with the inside Cooling plates with essentially vertical inner Pipes are connected at the top and bottom of the cooling plate from this pass through the steel jacket.
  • the cooling plate is on the side facing away from the steel jacket Side with a retaining cam or nose provided by another, in one pipe running essentially horizontally with connections led through the steel jacket runs, with at least part of the vertical Pipes over a considerable part of the vertical Dimension stretches.
  • FR-A 22 30 730 is a cooler for the Evaporative cooling of a blast furnace known from a plate with a cross near the end of the Plate arranged cantilever as well as from tubes which in the plate and in the said cantilever are, and in which a coolant flows.
  • the inlet and outlet ends of these pipes are open different heights on the opposite of the overhang Page arranged.
  • the pipe for the circulation of the Coolant in the cantilever is designed so that it is arranged in the cantilever so that the input and Exit ends between the exit ends of the in the Pipe laid pipes lie.
  • the ends of the parts of the circulation pipe in the cantilever, that are inside this projection are in arranged at an angle of 2 to 4 ° in the vertical, so that the circulation of the coolant from the inlet end to Outlet end of the pipes is rising.
  • US-4,071,230 are cooling elements for one Shaft furnace known on the inside of the furnace shell are attached.
  • the rectangular cooling element is made up of five on top of each other, arranged in a gap metallic blocks connected to two vertically running pairs of cooling pipes by means of suitable Fasteners are attached.
  • the pipe pairs with the lower cooling water inlet and the upper one Cooling water inlets are through openings in the led metallic furnace wall, the metallic blocks only become on the outside of the blast furnace directed side cooled.
  • a disadvantage of these rolled or forged Copper cooling plates is that the load capacity of the Masonry or the masonry at the head ends the cooling plate is not optimal and therefore the Service life of the refractory ramming masses or ff stones is not sufficient.
  • the object of the invention is therefore a To create a cooling plate with the reinforced head ends in the cooling system of the pocket oven be involved and the Heat dissipation in this area of the plates as well takes place evenly and homogeneously, so that there too improved cooling of the refractory furnace lining and of the furnace is guaranteed.
  • a bead can be used for fireproof masonry also from the rough copper block be forged, drilling the vertical and horizontal cooling tubes in this bead takes place in the known way.
  • Fig. 1 shows a longitudinal section through the cooling plate (1) with, for example, four vertically arranged blind holes (2, 3) and with the in the cooling element (4) vertical (5) and horizontal (6) blind holes.
  • Cooling water supply at the blind holes (3) takes place from below via the coolant supply lines connected pipe lugs (2), in the vertical and horizontal blind bores (5, 6) of the Cooling element (4) also via pipe sections (2).
  • the Cooling circuits of the cooling plate (1) and the cooling element (4) are supplied as separate cooling circuits to the Blast furnace cooling system connected.
  • Fig. 2 shows a section through the cooling plate (1) the vertically arranged blind holes (3), which are known Way at the lower end by welding or soldering points are closed.
  • the cooling water supply or discharge takes place via the pipe sections (2).
  • cooling plate (1) In the upper part of the cooling plate (1) there is a detachable one Cooling segment (4) attached in the vertical (5) and horizontal blind holes (6) are introduced.
  • the Horizontal blind holes (6) are also in the cooling plate (1) arranged to the cooling water supply and discharge over the pipe lugs (2) through the wall of the blast furnace (10) to ensure.
  • Fig. 3 shows a cooling plate (1) with one from the ingot forged bead (9) in which vertical (5) and horizontal (6) blind holes are made.
  • the horizontal blind bores (6) are also over here Pipe lugs (2) through the wall of the blast furnace shell (10) connected to the blast furnace cooling circuit.
