Abstract
Abstract An installation for electrically remelting a metal so that molten metal achieved in this way from a suitable electrode can be given a predetermined configuration in a mold. The molten metal in the mold is maintained at its elevated temperature during changing of a primary electrode by way of a secondary electrode, and a pair of carriage means are provided for respectively supporting these electrodes. One transporting means is operatively connected with the carriage means which supports the primary electrode to displace the latter away from the mold when it becomes necessary to exchange an at least partially consumed primary electrode with a new primary electrode. The secondary electrode supporting carriage and the mold form a pair of units one of which is acted upon by a second transporting means for displacing these units with respect to each other in such a way that when the primary electrode is displaced away from the mold the secondary electrode and mold coact with each other to maintain the molten metal at its elevated temperature, while the secondary electrode is maintained normally at an inoperative position displaced from the mold during the normal operations when the primary electrode coacts with the mold to supply the molten metal to the latter.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
373 words
In an installations for electrically remelting steel or like metal to mold a given body from the remelted metal, comprising in combination, at least vertically adjustable continuous castinG mold means for molding the molten metal to the configuration of said body; water cooling means operatively connected to said mold means for cooling the molten metal stored therein; at least vertically adjustable primary electrode carriage means for maintaining a primary electrode of the metal to be remelted in operative relation with the mold means during the remelting the remelting of the primary electrode to provide molten metal in the mold means; at least vertically adjustable secondary electrode carriage means for supporting a secondary electrode to coact with the mold means for maintaining the molten metal in the mold means at its elevated temperature during the time when an at least partially consumed primary electrode is displaced from the mold means by means of the primary electrode carriage means and is exchanged for a new primary electrode; first transporting means operatively connected to said primary electrode carriage means for transporting said primary electrode carriage means to a location remote from the mold means for replacing the partly consumed primary electrode with a new primary electrode and for then returning the new primary electrode to the mold means for continuing the casting operations at the mold means with the primary electrode while the secondary electrode is displaced from the mold means by said secondary electrode carriage means; said secondary electrode carriage means and said mold means forming a pair of units to be displaced one with respect to the other to situate the secondary electrode at an operative location with respect to the mold means only during the time when the primary electrode is being changed and is displaced from the mold means; and second transporting means operatively connected with said one of said units for maintaining said secondary electrode carriage means and said mold means normally at locations where the secondary electrode does not participate in the operations and for maintaining the secondary electrode and mold means in an operative relationship with respect to each other only during the times when an at least partially consumed primary electrode is replaced with a new primary electrode.
