Definitions

  • the invention relates to a cooling plate system for with a refractory lining shaft furnaces, in particular blast furnaces, the respective cooling plates made of copper or a low-alloy copper alloy with inside arranged coolant channels exist from a forged or rolled ingot are made and the cooling channels run vertically Blind holes are, with additional if necessary on the edge vertical and arranged in the cooling plate horizontal blind bores of smaller diameter or with a cooling element arranged on the cooling plate with vertical blind holes, each on End with horizontal blind holes are connected.
  • Such copper cooling plate systems are usually between the furnace jacket and the furnace lining and connected to the cooling system of the shaft furnace.
  • the Cooling plates On the side facing the inside of the stove are the Cooling plates largely with refractory material Mistake.
  • Cast copper plates are known in which the Cooling channels either through cast steel pipes are formed or cast directly.
  • the structure of copper casting is not as homogeneous and dense as that of forged or rolled copper. Consequently the heat conduction of copper casting is also worse and the strength less.
  • For the cast pipes prevents an oxide layer between the pipe and the copper block the heat conduction.
  • a cooling plate is known from a forged or rolled ingot is made and where the cooling channels are vertical running blind holes, which through mechanical deep drilling are introduced.
  • the structure the cooling plate is much denser and more homogeneous than that of a cast copper plate; Blowholes, like at Cast copper plates that occur frequently are excluded.
  • the strength values are higher than that of cast copper plates.
  • the target position of the holes according to height and side is adhered to exactly and thereby ensures even heat dissipation.
  • the cooling plate is facing the inside of the oven Side with webs and grooves and can be fireproof Stones or with a refractory ramming paste to be lined. This will make the cooling surface of the Plate reduced and in case of wear or the loss of the refractory furnace lining becomes the Heat removal from the oven is limited. Cooling the Plate should be so intense that the temperature of the hot plate side far below the softening temperature is held by copper.
  • the object of the invention is therefore a cooling system consisting of copper cooling plates create where vertically next to each other or copper cooling plates arranged horizontally one above the other so close inside a shaft furnace be that the heat dissipation also in the transition of Cooling plates take place evenly, so that there too Cooling the refractory furnace lining and the Furnace is guaranteed.
  • cooling plates for the formation of a horizontally arranged cooling plate system at least three cooling plates, for the formation of one complete horizontal cooling ring within the Oven tanks are a variety of cooling plates for which Formation of a limited cooling area are at least two cooling plates required.
  • One of the two cooling plates of the system according to claim 1 is therefore with double-sided, vertical and horizontal side flanges and with horizontally arranged, the Bars and grooves on the inside of the furnace Heat sink between the side flanges other cooling plate is also with bilateral, vertical and horizontal side flanges and with horizontally arranged, facing the furnace interior Ridges and grooves on the heat sink and the Side flanges or only the vertical side flanges Mistake.
  • One of the two cooling plates according to claim 2 with double-sided, vertical side flanges or with double-sided, horizontal side bottles and with horizontally arranged, facing the furnace interior Bars and grooves on the heat sink between the vertical or horizontal Side flanges, the other cooling plate also with vertical side flanges on both sides or with horizontal side flanges on both sides and with the furnace interior arranged horizontally facing ridges and grooves on the heat sink and the vertical or horizontal side flanges.
  • Cooling plates formed without horizontal side flanges become. The cooling plates however, they are laid joint to joint.
  • the invention is based on schematic Exemplary embodiments explained in more detail.
  • Figures 1 and 2 show a longitudinal section and a cross section of a first cooling plate (1).
  • the webs (9) and Grooves (10) are only limited to the heat sink (3), in which the vertical blind holes (4) are incorporated for the cooling water.
  • Figures 3 and 4 show a longitudinal section and a cross section of another cooling plate (2) with horizontal Side flanges (8).
  • the webs (9) and grooves (10) are both on the heat sink (3) and on the side elaborated vertical flanges (6) arranged, while the vertical blind holes (4) for the cooling water is limited to the heat sink (3).
  • a recess (13) is shown in FIG. 4 for Inclusion of a trunnion attached to the furnace wall on the opposite of the webs (9) and grooves (10) worked out narrower outside.
  • Fig. 5 shows the side view of a first cooling plate (1) with horizontal side flanges worked out above and below (7), the direction of the furnace (11) arranged are.
  • the heat sink (3) is alternately webs (9) and grooves (10) arranged.
  • the webs (9) and grooves (10) are expediently dovetail-shaped, to give the fireproof filling a better hold.
  • the cooling plate faces the blast furnace shell (11) facing side a recess (13) into which a Carrying pin (12) engages that on the blast furnace shell (11) is welded.
  • Fig. 6 shows the side view of another cooling plate (2) with horizontal side flanges worked out above and below (8), which are arranged towards the center of the furnace.
  • the webs (9) and grooves (10) are analogous to FIG. 5 arranged.
  • Fig. 7 shows a first cooling plate (1) with only laterally arranged vertical flanges (5).
  • the bridges (9) and grooves (10) are only on the heat sink (3) limited, in the vertical blind holes (4) are incorporated for the cooling water flow.
  • Threaded holes (16) are in the flanges (5) introduced to create a detachable connection Fastening elements between a first cooling plate (1) and produce another cooling plate (2) according to FIG. 9 can.
  • Fig. 8 shows another cooling plate (2) with only laterally arranged vertical flanges (6).
  • the webs (9) and Grooves (10) are both on the heat sink (3) and on the side flanges (6) arranged while the vertical blind holes (4) for the cooling water on the heat sink (3) are limited.
  • Fastening elements between a first cooling plate (1) and produce another cooling plate (2) according to FIG. 9 can.
  • a longitudinal section of two interconnected cooling plates (1,2) shows Fig. 9.
  • the webs (9) and Grooves (10) of the two cooling plates (1,2) run each horizontally in the same plane.
  • the fasteners (14) are arranged in the grooves (10) Bores in the area of the two overlapping Flanges (5,6) introduced.
  • Fig. 10 shows a partial plan view of the Arrangement of a cooling plate (1,2) existing cooling ring within a blast furnace.
  • the cooling plates (1,2) are each by means of recesses (13) on the support pin (12) of the furnace shell (11) suspended, the webs (9) of the cooling plates (1,2) are each facing the inside of the oven and are used for Inclusion of refractory material. Through the blind holes (4) the cooling water is led inside, the with the cooling circuit of the blast furnace stands.
  • the cooling plates (1,2) are each means Fastening elements (14) in the area of overlapping flanges (5,6) releasably connected.
  • In the flange (5) of the first cooling plate (1) is one Threaded hole (16) and in the flange (6) of the other
  • a cooling plate (2) is drilled into a hole (17).
  • Fastening element (14) is usually a hexagon screw, through the hole (8) and in the threaded hole (7) is screwed.
  • To secure the fasteners (14) are highly heat-resistant Sealing washers (15) used.
