Definitions
- the invention relates to wall elements for water-cooled, current-carrying electrode support arms and made of such wall elements Elektrodentragarme.
- Supporting arms for the electrodes of electric arc furnaces require high temperatures which occur during the melting process because of at least the area of the water cooling close to the furnace.
- the cooling of the electrode tensioning bow and the contact jaw which as a rule is also provided in this case, requires the independent supply of cooling water to the Elektrodenspannbügel and the contact jaw by the Elektrodentragarm associated pipes for the supply and discharge of cooling water for Elektrodenspannbügel and the contact jaw. It has been proposed in recent times already, for the cooling water flow extruded to provide the Elektrodentragarm forming wall elements with holes for cooling water circulation. (EP 0 594 272 B2). This eliminates the Elektrodentragarm enforcing or combined with the support arm separate piping systems. However, this proves to be disadvantageous in the elaborate preparation of the extruded wall elements with trained, closed channels for the cooling water circuit. Costly proves in this solution then also that it requires separate tools for the creation of wall elements with divergent dimensions and / or different cross sections of the intersecting cooling water channels.
- the invention has the object to design a cost-effective integrated in Elektrodentragarme wall elements cooling system, which then allows greater latitude in terms of cross sections of both the wall elements and the cooling water channels.
- the object is achieved with wall elements for water-cooled, current-carrying electrode support arms, which consists fiction, according to a consisting of electrically conductive metal flat profile in which on the outside of the Elektrodentragarms forming flat side at least one over the length of the profile extending recess is incorporated, the outside - And frontally with the flat profile by welding combined covers, a closed cooling channel resulting covers each having at least one access and at least one outlet for the coolant channel flowing through the cooling water is provided.
- Embodiments of the wall element according to the invention will become apparent from the dependent claims 2 to 7.
- the dependent claims 8 to I l cancel on from the wall elements according to the invention can be created from the electrode support arms.
- the Elektrodentragarme manufacturing company can use the already existing standard tools, such as saws, milling, welding equipment and drilling equipment, the components of the wall elements according to the invention, namely the return element having wall element and its cooling channel forming cover, create from cost endless material and The components of the wall elements then also summarize, from which in place the Elektrodentragarm is then assembled. It proves to be advantageous in this case also that can be created for the purpose of Anpgresparkeit to the specific application wall elements divergent width and length, then wall elements with divergent cooling channel sections readily with the available tools. From Elektrodentragarmen created by Wandungsettin invention then also results in the desired weight reduction of such electrode support arms.
- FIG. 2a shows the cropped starting material for the side walls of the electrode support arm, in cross section.
- FIG. 2b shows a representation corresponding to FIG. 2a with recesses milled into the main body of the wall element,
- FIG. 2c shows the completed wall element according to the invention
- 3 a shows the cut starting material for the lower and the upper wall element of the electrode support arm, in cross-section
- FIG. 3 b shows a representation corresponding to FIG. 3 a, with a recess milled into the base body
- FIG. 3c shows the completed wall element
- FIG. 4 shows a cross-section close to the furnace vessel through an electrode support arm made from wall elements according to the invention
- FIG. 5 shows a cross section through the electrode carrier arm corresponding to FIG.
- 1 1 denotes the furnace vessel, in the scrap generally used below
- the electrodes 12, 12 '12 are clamped (131) at the free end of the electrode support arms 13, 13', 13", they become in accordance with the progressive Ab
- Both the emptying of the furnace vessel 11 after completion of the melting process, usually by tilting the furnace vessel 11, as well as for the replacement of the electrodes requires both the lowering and lifting of the electrodes 12, 12 ', 12 ", then also the Cirverschwenkens the electrodes from the immediate area of the furnace vessel 1 1.
- the electrode support arms 13, 13', 13" on a Tragarmklale 14 in the sense of the double arrow A can be lowered and raised and in the sense of the double arrow B are mounted pivotably in the horizontal, the electrode support arms 13, 13 ', 13 "and the clamps located at the free end of the electrode support arms 131 for the electrodes 12, 12 ', 12 "require, in view of the high temperatures occurring in the surroundings of the furnace vessel 11 during the melting process, intensive cooling, generally cooling water supplied by the support arms and the clamping straps.
- FIGS. 2 a and 3 a Components of the wall elements according to the invention for electrode support arms tailored from endless material are shown in FIGS. 2 a and 3 a. These are the main body 22 forming the wider side walls and the base body 32 having a smaller width, forming the lower and upper walls of the electrode support arms, and the smaller thickness covers 23, 23 "and 33, respectively, which complete the wall elements.
- FIGS 3b the base bodies 22 and 32 of the wall elements 21 and 31 can be seen with recesses 24 and 34 milled in.
- Figures 2c and 3c show the completed wall elements 21 and 31 with the cooling water channels 27, 27 'and 37 formed therein.
- the permanent combination of the covers 23 with the main body 21 of the wall element 21 by countersunk (25) welds 26 is shown in Fig.
- the cooling channels 44, 44 '"formed in the side walls 42, 42 are flowed through by the cooling water which acts on both the electrode support arm and the electrode tensioning bow
- the supply and discharge of the cooling water to or from the electrode clamping bracket is not illustrated by the arrow sequence C
- cooling water is applied independently to the side walls 42, 42 'and the wall elements 43, 43' forming the lower side and the upper side of the electrode support arm, as well as the electrode clamping yokes and the contact jaw 46, 46 'are the ports on the outside of the cooling water circuit in the Elektrodenspannbügel located on the cooling channels 44', 44 "in the side walls 42, 42 'lie.
- Branches for branching from one to a plurality of sections of sectioned cooling ducts 44, ..., 44 'extending along the length of the side walls are designated 47, 47', in the region to which reference numeral 49 is assigned it is the attachable revision area of the electrode support arm.
- FIG. 5 shows the stiffening of the electrode support arm by intermediate walls 48 inserted into it, which are provided with recesses 48 'for reasons of weight reduction.
- the design of the wall thickness of the electrode support arm depends on the specific application, then the design of the cooling duct cross-sections.
- the priority cooling of the electrode support arm via the cooling channels formed in the support arm walls does not preclude the cooling of the region of the electrode support arm adjacent to the furnace by the supply of cooling water to near-isolated regions.
- the cooling water circuit also results here again by leading from the cooling water channels in walls of the Elektrodentragarms outgoing and outgoing.
