Definitions

  • the invention relates to a cooling plate for with a 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 made from a forged or rolled ingot and the cooling channels as vertical Blind holes are arranged.
  • 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.
  • Cooling plates are known in which the cooling channels are formed by pipes cast in cast iron. These plates have little heat dissipation as a result the low thermal conductivity of cast iron and because of the resistance between the cooling pipes and the Plate body caused by an oxide layer or an air gap.
  • a cooling plate is known made from a forged or rolled tube block is and where the cooling channels run vertically Blind holes are through mechanical deep drilling are introduced.
  • the structure of the cooling plate is much denser and more homogeneous than that of a cast copper plate; Blowholes, as they are common with cast copper plates occur are excluded.
  • the strength values are higher and the thermal conductivity is more even and higher than that of the cast copper plates.
  • the target position of the holes according to height and side is adhered to exactly and therefore even heat dissipation guaranteed.
  • the cooling plate faces the inside of the furnace Side with refractory bricks or with a refractory Rammed earth lined. This will make the heating 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.
  • a disadvantage of these rolled or forged Copper cooling plates is that cooling to the Marginal zones is not optimal and therefore cooling the joints of the refractory ramming compounds or ff-stones between the cooling plates is not sufficient.
  • the object of the invention is therefore a To create a cooling plate in which the edge zones in the Cooling system to be included and heat dissipation in the Plates are made more evenly and homogeneously, so that improved cooling of the refractory furnace lining and the furnace is guaranteed and thereby longer service lives can be achieved. Furthermore, the Suspension of the cooling plate on the furnace shell improved to better reduce thermal stresses in the cooling plate to be able to.
  • 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 marginal areas of the Cooling plate (1) introduced vertical (13) and horizontal (14) Small diameter blind holes.
  • Cooling water supply at the blind holes (3) takes place via the with the coolant supply lines connected pipe lugs (2), in the vertical and horizontal blind bores (13, 14) of smaller diameter over the pipe section (5) in the area of Transport hook (8) of the cooling plate (1) is arranged.
  • the cooling water leaves the cooling plate (1) via the Pipe pieces (2 ') or (5').
  • Fig. 2 shows a section B-B through the cooling plate (1) in the area of the vertically hooked blind holes (3), at the lower end due to welding or soldering points (4) are closed.
  • the cooling water supply and discharge takes place via the pipe sections (5) or (5 ').
  • Fig. 3 shows a section A-A through the cooling plate (1) in the area of the vertical blind holes (13) with a welding or Solder joint (4) and a cut through the horizontal blind holes (14).
  • Fig. 4 shows a section C-C through the Cooling plate (1) in the area of the transport hook (8) Cooling water is supplied 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 by an additional Trunnion (11) attached to the blast furnace shell (10) is to be held. This trunnion (11) engages in the recess (12) facing away from the inside of the furnace Side of the cooling plate (1).
