Definitions

  • the invention relates to a cooling plate for shaft furnaces provided with a refractory lining, in particular blast furnaces, consisting of copper or a low-alloy copper alloy with coolant channels arranged in their interior, the cooling plate being made from a forged or rolled ingot and the cooling channels being arranged as vertically running blind bores .
  • Such cooling plates are usually arranged between the furnace shell and the furnace lining and connected to the cooling system of the shaft furnace. On the side facing the inside of the furnace, the cooling elements are partially provided with refractory material.
  • Cooling plates are known in which the cooling channels are formed by pipes cast in cast iron. These plates have a low heat dissipation due to the low thermal conductivity of the cast iron and because of the resistance between the cooling tubes and the plate body, caused by an oxide layer or an air gap.
  • Plates made of cast copper are also known, in which the cooling channels are either formed by cast pipes or are cast directly.
  • the structure of cast copper is not as homogeneous and dense as that of forged or rolled copper. As a result, the heat conduction of copper casting is poorer and the strength is lower.
  • an oxide layer between the pipe and the copper block prevents heat conduction.
  • a cooling plate which is made from a forged or rolled tube block and where the cooling channels are vertical blind holes, which are introduced by mechanical deep drilling.
  • the structure of the cooling plate is much denser and more homogeneous than that of a cast copper plate; Blowholes, as they often occur with cast copper plates, are excluded.
  • the strength values are 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 adhered to exactly, thereby ensuring even heat dissipation.
  • the cooling plate is lined with refractory bricks or with a refractory ramming compound on the side facing the furnace interior.
  • the heating surface of the plate is reduced and in the event of wear or loss of the refractory furnace lining, the heat removal from the furnace is limited.
  • the cooling of the plate should be so intensive that the temperature of the hot plate side is kept well below the softening temperature of copper.
  • a disadvantage of these rolled or forged copper cooling plates is that the cooling at the edge zones is not optimal and therefore cooling of the joints of the refractory ramming compounds or ff-stones between the cooling plates is not sufficient.
  • the object of the invention is therefore to provide a cooling plate in which the edge zones are included in the cooling system and the heat dissipation in the plates takes place more uniformly and homogeneously, so that improved cooling of the refractory furnace lining and the furnace shell is ensured and thereby longer service lives can be achieved. Furthermore, the suspension of the cooling plate on the furnace armor plate is to be improved in order to better reduce thermal stresses in the cooling plate.
  • additional cooling channels are therefore introduced into the forged or rolled copper cooling plate, which are introduced as vertical or horizontal blind bores of smaller diameter around the vertically arranged blind bores in the edges of the cooling plate. These vertical and horizontal blind holes are sealed at the ends by welded or soldered plugs.
  • At least one centrally arranged recess is also provided, into which a support pin fastened to the blast furnace shell engages.
  • Fig. 1 shows a longitudinal section through the cooling plate (1) with, for example, four vertically arranged blind bores (2, 3) and with the vertical (13) and horizontal (14) blind bores of smaller diameter made in the edge regions of the cooling plate (1).
  • the cooling water for the blind bores (3) is supplied via the pipe attachments (2) connected to the coolant supply lines, for the vertical and horizontal blind bores (13, 14) of smaller diameter via the pipe section (5) located in the area of the transport hook (8) the cooling plate (1) is arranged.
  • the cooling water leaves the cooling plate (1) via the pipe sections (2 ') or (5').
  • a recess (12) is arranged in the center of the cooling plate (1) on the side facing away from the inside of the furnace, into which a support pin of the blast furnace shell engages.
  • Fig. 2 shows a section B-B through the cooling plate (1) in the region of the vertically hooked blind holes (3) which are closed at the lower end by welding or soldering points (4).
  • the cooling water is supplied and removed via the pipe sections (5) and (5 ').
  • grooves (6) are worked into the cooling plate (1) on the side facing the inside of the furnace, which are each delimited by webs (7).
  • Fig. 3 shows a section A-A through the cooling plate (1) in the region of the vertically introduced blind holes (13) with a welding or soldering point (4) arranged at the upper end and a section through the horizontal blind holes (14).
  • Fig. 4 shows a section C-C through the cooling plate (1) in the region of the transport hook (8), the cooling water supply to the blind holes (14) via the pipe sections (5), the cooling water discharge via the pipe sections (5 ').
  • the cooling plate (1) itself can be held by an additional support pin (11) which is attached to the blast furnace shell (10). This support pin (11) engages in the recess (12) on the side of the cooling plate (1) facing away from the interior of the furnace.
