Definitions
- the invention relates to a cooling device for electrodes of a metallurgical furnace, such as reduction furnace, electric arc furnace, induction furnace, etc., which encloses at least one contact jaw and a mounting ring, consisting of a cooling shield / sealing cylinder, which merges into an end region consisting of an outer ring, a face plate and an inner ring,
- this device provides, according to DE 1 022 332, for an electric drafting device for arc and reduction furnaces, with a sealing cylinder surrounding the socket, projecting into the furnace chamber and preferably height-adjustable supported on the furnace cover, in which the mounting parts are in an upwardly open cylinder are arranged, while the seal is below the upper edge of the contact jaws, wherein the contact jaws are surrounded by a reaction of the contact pressure against the electrodes receiving abutment.
- Electrodes Further details on electrodes, electrode sockets, mounting rings, contact jaws, etc. are in the publications DE 10 26 017, DE 14 40 358, DE 14 40 358, DE 23 12 099, DE 33 40 390 C2, DE 36 30 861 C2 and DE 43 42 511 C2. From DE 34 OO 186 C2 a passage for a plurality of electrodes through the lid of an electric arc or reduction furnace, each with a double-walled water-cooled hollow cylinder made of electrically conductive material is known.
- the implementation comprises in each case an electrode and, when using Tief chargeden, the axis-parallel around the electrode arranged current guides and contact jaws.
- An electrode base for arc or reduction furnaces is described in DE 21 25 773 C3.
- the power supply parts lying in the furnace area in particular current conductors, socket parts and the like, are protected by a double-walled, water-cooled cooling jacket arranged coaxially to the electrode.
- the cooling jacket extends to the cooled mounting ring and is detachable from this.
- the cooling jacket is divided by a transverse plane to its axis in an upper cylindrical and a lower cylindrical portion. The lower part is subdivided into interconnected, coolant-flowed segment-like cooling shields.
- FIG. 1 shows a known embodiment of a cooling device.
- the cooling device is assembled from several individual parts, in particular welded together. The simplest possible shapes are taken into account in the individual parts.
- the known cooling device consists of an inner ring which is welded at an angle with an annular end plate in the region of the electrode. The outer portion of the end plate shows in cross-section a radius which merges into a cooling plate or sealing cylinder.
- the front area of cooling shield or sealing cylinder consists of two parts, an inner ring and a face plate. In the front area are cavities for passing a cooling medium, e.g. Cooling water.
- the invention has for its object to improve the known cooling device so that high voltages are avoided, which in particular bring the disadvantages mentioned above with it. With an improved design of the cooling device whose safety and durability should be improved.
- the cooling device is integrally formed in the forehead area.
- the decisive advantage of the cooling device according to the invention is that the welds in the forehead area are displaced or avoided. Due to the special shape of the cooling device in the stimulus area a lower attack surface for wind instruments (heat) is achieved.
- the improvements shown avoid or reduce furnace downtime and improve the safety and durability of those located within the cooling device.
- Fig. 1 in a sectional side view of a cooling device in a known
- FIG. 2 in a sectional side view of a cooling device according to the invention
- an electrode 1 with adjacent contact jaw 2 and to corresponding socket ring 3 is shown in a known embodiment.
- the cooling device 4 consists of a cooling plate / sealing cylinder 5, which merges into an outer ring 6 in the lower region.
- the outer ring 6 forms with a front plate 7 and an inner ring 8 a stimulus region 9, wherein the downwardly projecting electrode 1 protrudes beyond the end region 9 of the cooling device 4.
- Inner ring 8 and end plate 7 are in the contact area 10, outer ring 6 and end plate 7 are welded together in the contact area 11 and have welds 12, 13.
- FIG. 2 shows the cooling device 4 according to the invention in a sectional side view.
- the end portion 9 is formed in one piece and has no shit on.
- the cross-sectional shapes of the end region 9 can be designed differently according to the requirements or the material used.
