Description of the Related Art Conventionally, as a double vacuum degassing apparatus, two vacuum tanks are movably equipped, and a ladle truck is provided between the two vacuum tanks at the time of retreat so as to intersect the moving direction. A movable installation is proposed (Japanese Patent Publication No. 45-41).
482). In this conventional apparatus, when it is necessary to repair or dry one vacuum tank on one side, a vacuum degassing process is performed at a position where the moving direction of the vacuum tank intersects with the moving direction of the ladle truck. It is moved backward from the position for repairing and drying, and during that period, one vacuum chamber on the other side is moved forward to the above intersecting position for vacuum degassing treatment. However, such a conventional device has a drawback that productivity is poor in light of the vacuum degassing process.

従来装置では真空脱ガス処理が跡切れる。In practice of the vacuum degassing process, for example, two newly installed vacuum chambers are often used alternately and repeatedly under substantially the same conditions, and therefore it is necessary to repair the two vacuum chambers at the same time. In some cases, the conventional apparatus cannot perform the vacuum degassing process. Further, for example, when it becomes necessary to repair one vacuum tank for a long period of time for some reason, the other one vacuum tank cannot cover the gap, so even in such a case, the vacuum decompression by the conventional apparatus is performed. Gas treatment is cut off.

ある。The present invention is equipped with a total of three vacuum chambers, of which two vacuum chambers are on the main road on one side of the turntable and the remaining one vacuum chamber is on the turntable. Each of the main road and the sub road on the other side is movably equipped. Then, when the two vacuum tanks installed in the main road on one side are retracted for repair or drying, the truck for ladle crosses over the main road on one side between the two vacuum tanks. The moving path of is set up. One vacuum tank is movably installed on each side of the position where the main road on one side of the turntable intersects with the moving path of the ladle truck, that is, the position where the vacuum degassing process is performed. One of the vacuum tanks is installed on the other side of the turntable so that it can be moved, and a repair table or a dryer is installed at the position where these vacuum tanks are retracted from the main path or the auxiliary path. -ing

処理の実際に照らして、生産性を向上できる。In a normal case, a total of two vacuum chambers mounted on both sides of the vacuum degassing position are alternately and repeatedly used. When it becomes necessary to repair the two vacuum tanks at the same time, one of the vacuum tanks is retracted to the main road on the other side through the turntable, and the other one is waiting on the auxiliary road. The vacuum chamber of 1 is advanced to the main road on one side through the turntable, and the other vacuum chamber of 1 is temporarily used. If it becomes necessary to repair one of the two vacuum chambers that are used alternately in the normal case for a long period of time, the one vacuum chamber is connected via a turntable. Back to the main road on the other side, and another vacuum tank waiting on the secondary road is advanced to the main road on the other side through the turntable, and alternates with the remaining one vacuum tank. Use repeatedly. Therefore, according to the present invention, productivity can be improved in the light of the vacuum degassing process.
