Definitions
- the invention relates to cooling plates 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 with a straight inside made of one forged or rolled ingot is made, the cooling channels are blind holes on the inside, with side flanges arranged at the edge of the cooling plate and with pipe lugs at the ends of the cooling channels.
- Such copper cooling plates are usually between the furnace jacket and the furnace lining and connected to the cooling system of the shaft furnace.
- the Cooling elements in the upper part of the shaft furnace largely with fireproof material, in the area of the frame with Carbon stones covered.
- 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 is also the heat conduction of copper casting 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 made from a forged or rolled ingot is 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.
- the strength values are higher than that of the cast copper plates.
- the debit position the holes in height and side are strictly observed and thereby even heat dissipation guaranteed.
- This cooling plate faces the inside of the furnace Side with webs and grooves and can be fireproof Stones or with a refractory ramming paste to be lined.
- EP 0 705 906 A1 describes one made from a forged one or rolled copper tube block made cooling plate known for cooling the peripheral zones in addition to the vertical blind holes Cooling channels are introduced, which as vertical or horizontal blind bores of smaller diameter around the vertically arranged blind holes in the edges will.
- DE 196 03 912 A1 is one of one forged or rolled copper pipe block Cooling plate known in addition to the vertical running blind holes in the upper or lower Area an additional cooling element, detachable or forged, is attached in the additional vertical and horizontal blind holes are introduced and the over copper pipe socket also with the cooling system of the blast furnace.
- Cooling plates consisting of copper or a low-alloy Copper alloy with inside arranged Coolant channels, known, the cooling plate made from a forged or rolled ingot is and the cooling channels vertical blind holes are.
- the cooling plates are vertical on both sides Side flanges and / or with double-sided, horizontal Side flanges and with horizontally arranged, the Bars and grooves facing the inside of the furnace on the heat sink Mistake.
- the cooling plates are designed so that the vertical or horizontal side flanges at the Interlock overlapping assembly on the furnace shell and thus cooling segments or rotating cooling rings form.
- they are Side flanges on the inside of the furnace Side
- the other type of cooling plate are the Side flanges on the side facing the furnace arranged.
- the object of the invention is therefore a cooling system consisting of copper cooling plates create vertically next to each other or horizontally copper cooling plates arranged one above the other attached to the furnace shell of a shaft furnace be that between the cooling plates and the furnace no fireproof lining or other insulation or Insulating materials required on a larger scale becomes.
- the inner blind holes and with vertical and / or arranged on both sides horizontal side flanges provided heat sink the forged or rolled copper cooling plate an arched exterior and one just finished inside.
- the curved outside of the respective cooling plate is on the respective diameter of the blast furnace or Location in the blast furnace - rack, rest, coal sack u. a. - adjusted, d. H. the radius of the Place of use in the blast furnace and the radius of the arched Outside of the cooling plate are largely identical.
- Both types of cooling plates are therefore on the Furnace-facing side with double-sided, vertical side flanges provided, the the Side facing the furnace, both with and without Bars and grooves on the heat sink between the side flanges can be equipped.
- the other side of the both cooling plates comes with a curved outside, which is adapted to the radius of the furnace shell.
- the vertical side flanges of the cooling plates are hence to the inside of the blast furnace, on the other arranged to the outside of the blast furnace, the furnace shell.
- One of the cooling plates is the one that was just executed Inside seamlessly in the side flange at the other cooling plate goes the arched Outside seamlessly into the side flange.
- Cooling plates can be designed to overlap.
- Horizontal cooling segments or complete cooling rings can also be stacked inside a blast furnace due to cooling plates without horizontal side flanges be formed.
- the cooling segments or complete Cooling rings are then laid butt to butt.
- the invention is based on schematic Exemplary embodiments explained in more detail.
- FIG. 1 shows a side view of a cooling plate (1) with an arched outer side (8), the is directly connected to the furnace shell (11).
- the pipe sections (10) are vertical blind holes (4) led to the cooling system of the blast furnace.
- the straight version facing the inside of the oven The inside (7) of the cooling plate (1) connects directly a lining, not shown, of carbon bricks on.
- Fig. 2 shows a longitudinal section through a cooling plate (1) with dashed lines in the heat sink (3) Blind holes (4) and to the side of the heat sink (3) arranged vertical side flanges (5) and emerging at the head and foot of the heat sink (3) horizontal blind holes (9).
- Fig. 3 shows a cross section through the cooling plate (1), the side flanges (5) being a direct lateral extension of the inside just finished (7) can be seen.
- Side (8) of the cooling plate (1) shows one curved outside into which the pipe lugs (10) for The cooling water discharge is incorporated.
- Fig. 4 shows a longitudinal section through a cooling plate (2) with dashed lines in the heat sink (3) Blind holes (4) and laterally from the heat sink (3) vertical side flanges (6) and emerging at the top or bottom of the heat sink (3) Blind holes (9).
- Fig. 5 shows a cross section through the cooling plate (2), the side surface (6) being a direct lateral extension of the curved exterior (8) can be seen.
- the inside (7) of the cooling plate (2) also shows a straight embodiment here.
- the pipe lugs (10) are here also on the curved Outside (8) for supplying and discharging the cooling water incorporated.
- Fig. 6 shows a top view of the arrangement of a Cooling ring on the furnace shell (11) in a blast furnace.
- the cooling ring alternately consists of the cooling plates (1) and (2) together, with the arched outer sides (8) the cooling plates (1, 2) close to the furnace (11) and the side flanges (5) of the cooling plate (1) each the side flange (6) of the cooling plate (2) overlaps.
