Definitions
- the invention relates to a cooling plate for with a refractory lined furnaces, Direct reduction reactors and melter gasifiers Iron and steel industry consisting of cast Copper or a low-alloy copper alloy coolant channels arranged in their interior.
- Such copper cooling plates are usually between the furnace jacket and the furnace lining and to the cooling system of the metallurgical furnace connected. On the inside facing the oven The cooling elements in blast furnaces are largely included provided with fireproof material for steel melting furnaces the copper cooling elements, however, are in the upper part of the furnace over the fireproof lining.
- Cast copper plates are known in which the Cooling channels are formed by cast steel pipes.
- An oxide layer hinders the cast-in steel pipes as well as an insufficient connection a uniform between the steel tube and copper plate Heat dissipation.
- a cooling plate is known from DE 29 07 511 C2, 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 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 with refractory stones or with a refractory Ramming compound lined.
- EP 0 705 906 A1 describes one of a forged or rolled copper blank Cooling plate known for cooling the edge 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 be introduced.
- the object of the invention is therefore a To create copper cooling plate, its thermal conductivity approximately that of a forged or rolled Cooling plate corresponds, however, considerably is cheaper to manufacture.
- Cooling plate prefabricated curved cooling pipes or Coolant channels consisting of copper pipes, Copper pipe bends and copper pipe lugs, cast in.
- pipes are in several rows next to each other and / or one above the other arranged.
- the hairpin - shaped sides of the head Cooling channels are formed either by curved ones Pipes or through pipe bends or reversing caps.
- the inputs and Spouts are provided with pipe lugs.
- the complete pipeline is welded and then for tightness by means of a pressure test of approx. 15 bar / 20 min. checked.
- the pipes, pipe bends and pipe lugs must, however be thick-walled than commercially available pipes, because after the cast, they are raised for several hours Exposed to temperature in the mold are.
- the completely prefabricated pipeline is in the Mold inserted, fixed in the lower case and then with poured over the copper melt so that the pipeline after the melt solidifies in the copper plate is embedded.
- the flow and the flow rate of the Cooling medium is through the rounded piping compared to the angular transitions in the drilled cooling channels of a forged or rolled plate improved and harmonized.
- Cooling plate bars and grooves for holding refractory material required which is either cast directly or by mechanical processing from a smooth wall can be worked out.
- the inside of the plate is expedient smooth or flat because of the inside is not provided with a fire-resistant lining.
- cooling plates form a rotating cooling ring can be assembled, can be bilateral vertical side flanges are provided.
- cooling plates also with horizontal side flanges be provided.
- the invention is based on schematic Exemplary embodiments explained in more detail.
- Fig. 1 shows a longitudinal section through the cooling plate (1) with, for example, four vertically arranged cooling pipes (2, 3, 4) inside the cooling plate (1) as well as recesses made in the outer wall (6) (12).
- the supply of cooling water to the pipes (3) takes place from below via the coolant supply lines of the blast furnace connected pipe approaches (2).
- the coolant lines (2, 3, 4) of the cooling plate (1) are used as separate cooling circuits to the cooling system connected to the blast furnace.
- Fig. 2 shows a section through the cooling plate (1) the vertically arranged coolant lines (2, 3, 4) on the inner wall (5) with webs (7) and grooves (8) and on the outer wall (6) with a recess (12) are provided, in which a trunnion (11) of the blast furnace (10) engages.
- Fig. 3 shows a longitudinal section through a cooling plate (1) Intended for use in an arc furnace is provided.
- the coolant lines (3, 4) are arranged in a serpentine shape and have only two copper pipe lugs (2) for the supply or removal of the cooling water.
- the copper pipes (3) and copper pipe bends (4) are before Casting of the cooling plate has been welded together, the same applies to the two copper pipe approaches (2).
- Fig. 4 shows a cross section through a cooling plate (1), the inner wall (5) of which is a flat surface (9) having.
- the cooling water supply or cooling water discharge through the coolant lines (3, 4) takes place over two Copper pipe lugs (2) on the outer wall (6) are attached and connected to the cooling water circuit of the Arc furnace can be connected.
- FIG. 5 and 6 show longitudinal sections through two cooling plates (1) compared to the embodiment according to FIG. 1 with vertical (13) and horizontal side flanges (14) or according to Fig. 6 only with horizontal Side flanges (14) are equipped.
- Both cooling plates (1) have four vertically inside arranged cooling pipes (2, 3, 4) and recesses (12) on the outer wall (6).
