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 the electrode and consists of individual segments.
- a metallurgical furnace such as reduction furnace, electric arc furnace, induction furnace, etc.
- DE 36 30 861 C2 discloses an electrode holder for electric arc or reduction furnaces, with a plurality of electrodes guided through the furnace lid, with cylindrical capsules arranged concentrically with the individual electrodes and with current supply means parallel to a part of their length as current tubes extend to the electrode with its axes on a cylinder concentric to the electrode and thereby occupy only a portion of the cylinder circumference and are arranged at the furnace vessel bottom facing the end to the electrodes contactable contact jaws.
- each capsule has at least two shell openings which each extend over a part of the circumference in their width. In these jacket openings the coaxial with the capsule guided power pipe sections of the power supply device are arranged and united by embedding, Umgie head or the like.
- the electrode is enclosed below a gas exhaust hood up to the current-carrying jaws of the cooling device.
- the removable cooling shields allow easy access to the clamping device or the current-carrying jaws during maintenance.
- the cooling shields must be removed individually, loosened by screws, pull bolts, use lifting device or similar, etc. This time consuming process affects the production, the furnace runs in the Conti - operation and has an availability of about 97% per year. When loosening and removing the cooling shields may also cause damage to the water-bearing parts.
- the invention is therefore based on the object to improve the known cooling device so that the access to the electrode is simplified and the above-mentioned disadvantages are avoided.
- the availability of the furnace should be improved.
- the invention also relates to a method for pivoting at least one individual segment.
- the decisive advantage of the cooling device according to the invention is that the one or more individual segments are removed by simply pivoting away from the electrode. A hoist or the like is not needed. The individual segments need not be stored but are attached to the access to the electrode at this or their holding devices.
- the cooling circuit is maintained by, for example, the cooling water inlet and the cooling water drain via flexible lines. These are designed so that they do not obstruct or limit the pivoting process.
- the improvements shown reduce oven downtime because maintenance times are reduced.
- Fig. 1 in a three-dimensional view a cooling device consisting of
- FIG. 1 shows a cooling device 1, comprising a plurality of individual segments 2, 3, 4, 5.
- the individual segments 2, 3, 4, 5 are, for example, fastened individually to a hanging frame 6 by at least one hinge 7.
- additional hinges 7 can also be taken into account.
- the individual segments 2, 3 are pivoted away from the electrode (not shown) by the hinges 7.
- each individual segment 2, 3, 4, 5 can be pivoted by a hinge alone.
- two adjacent individual segments 4, 5 can be articulated by one or more hinges 8, wherein the individual segment 5 is connected to the hanging frame 6 by a hinge 7.
- the single segment 5 can be connected by means of hinges 8 with a further single segment.
- a cooling device 1 is shown in plan view, in which all individual segments 2, 3, 4, 5 are individually connected by a hinge 7 with the hanging frame 6.
- the individual segments 2, 3, 4, 5 are for this purpose formed with a rotary joint 9, to which the hinge 7 is attached.
- Each individual segment 2, 3, 4, 5 has at least one cooling water inlet 10 and at least one cooling water outlet 11. These are connected via flexible lines (not shown) to a cooling circuit. Alternatively, two adjacent individual segments 2, 3, 4, 5 may have a common cooling circuit.
- At least one hinge web 12 may be formed telescopically.
