る。2. Description of the Related Art Generally, in a steel mill, dephosphorization and decarburization of hot metal (smelting operation) is performed by pouring hot metal dephosphorized by a converter into an empty hot metal pot placed on a transport cart. The hot metal pot containing the hot metal is moved to a predetermined location by the transport trolley, and the hot metal pot is lifted from the trolley by a crane and transported to another converter for performing the decarburization process in the next process. Then, the hot metal of the hot metal ladle is transferred to the converter for decarburization treatment, the empty hot metal ladle is transported again by a crane to above the standby place of the bogie, mounted on the transport bogie, and the transport bogie is It has been practiced to move it again to the taphole of the dephosphorization converter. By the way, an example of a conventional cycle time when a dephosphorization converter and a decarburization converter as shown in FIG. 5 are arranged in a row in the same building and dephosphorization and decarburization processing operations are performed. It is shown in FIG. As shown in FIG. 6, the cycle time (one cycle from tapping to the next tapping) of the converter for dephosphorization and the converter for decarburization takes about 23.5 minutes. In this cycle time, `` wasteful waiting time '', that is, refining is finished and tapping can be performed until the hot metal ladle once received is emptied again, reaches below the taphole and is ready for tapping Nevertheless, there is a wasteful waiting time that can be kept waiting in the converter. This wasteful waiting time is due to the fact that the hot metal ladle, which has received hot metal from the dephosphorization converter, is transported to the decarburization converter, loaded into the converter and emptied, and then dephosphorized again. This occurs due to a time lag between the time when the iron falls back below the tap hole of the converter and the time when the next dephosphorization operation is completed in the converter for dephosphorization and the iron is ready for tapping again. That is, in the transfer of hot metal between the two converters by one hot metal ladle and one crane, the hot metal ladle receiving the dephosphorized hot metal is transferred to a decarburization converter by a crane, transferred and emptied again. The molten hot metal ladle is transported to a transport trolley, mounted on it, and moved again under the tap hole of the dephosphorization converter. And the next empty hot metal ladle cannot be prepared under the dephosphorization converter until the crane and carrier cart return to the dephosphorization converter again. This is due to the waiting state. As an example of such an arrangement, for example,
There is one disclosed in FIG. 1 of Japanese Patent No. 41624, in which dephosphorization and decarburization operations are performed using two converters. These two converters are located in the same converter building, respectively, and carts for transporting the hot metal pot between the converter back building, the converter building, and the converter front building are provided under each converter. Rails are laid so that you can run while passing. Then, the bogie is moved to the tap hole of the converter to transfer the hot metal in the converter after dephosphorization to the hot metal pot on the transport trolley. Is transported to a predetermined place by a transport trolley, and then transported by a crane to a converter for decarburization. The transferred hot metal in the hot metal ladle is transferred to a decarburization converter, and then the empty hot metal ladle is again transported to the bogie by a crane and mounted on the bogie. And the dephosphorized hot metal is again poured into the hot metal pot. As described above, hot metal transfer between the two converters by one hot metal ladle and one crane requires:
There is a limit to shortening the cycle time due to the useless waiting time described above. By the way, in the hot metal treatment in the converter, the refining time (blown time) for dephosphorization and decarburization takes about 15 minutes in the above-mentioned publication, but in recent years, in the 220 t converter, The refining operation can be completed in about 10 minutes, and the shorter the refining time is, the better the cycle time is, and it tends to be shorter in the future. However, in the above conventional hot metal transfer apparatus between converters, even if the refining is completed in about 10 minutes, the hot metal pot being poured into the decarburizing converter is returned to the tap hole of the dephosphorizing converter again. Until it is prepared below, the dephosphorization converter cannot tap and waste time, so despite the shortening of the refining time as described above, There is a problem that is not shortened.

約２０分）。The dephosphorized hot metal is received in a hot metal ladle and transported to another converter by a crane for transfer. Since the emptied hot metal ladle was transported to the hot metal ladle setting device by a crane so that it could be directly transferred to the hot metal ladle setting device,
As soon as one of the hot metal pans on the transport trolley is lifted by the crane and the transport trolley is emptied, the other hot metal pan supported by the hot metal ladder setting device can be immediately mounted on the transport trolley. Even while the hot metal pot is charging hot metal into the decarburizing converter, the other hot metal pot can be moved below the tap hole of the dephosphorizing converter. The required time from tapping into one hot metal pot until the other hot metal pot is prepared under the tap hole of the dephosphorization converter is much longer than the cycle time of dephosphorization and decarburization treatment. Short. Therefore, the wasteful waiting time (3.5 minutes in FIG. 7) is eliminated, and the cycle time can be reduced (about 20 minutes in FIG. 6).

性の向上を図ることができる。According to the present invention, by installing the hot metal ladle setting device, two hot metal ladles can be used. As a result, one hot metal ladle is used for charging the decarburization converter. The other one is supported on a hot metal ladle setting device by a crane that has transported an empty hot ladle, and the crane lifts one hot ladle on the trolley for charging into the decarburization converter, As soon as the transport trolley is empty, another hot metal pot supported by the hot metal ladle setting device can be mounted on the transport trolley by the lowering operation of the lifting frame of the hot metal ladle setting device. Even while hot metal is being charged into the decarburization converter, the other hot metal pot can be quickly moved to the taphole of the dephosphorization converter. Therefore, it is possible to immediately tap the prepared hot metal into another hot metal ladle without retaining the dephosphorized hot metal in the converter, thereby improving the operation efficiency of the converter and improving the production efficiency. it can. In addition, the hot metal ladle setting device mounted on the transport trolley between the dephosphorization converter and the decarburization converter is installed at a predetermined location on the traveling rail of the transport trolley, so that the other hot metal ladle setting device can be used for the other hot metal ladle setting device. Since the hot metal pot that has been emptied by charging the hot metal into the furnace can be immediately delivered from the crane to the hot metal setting device, the carrier truck that transfers the hot metal pot suspended from the crane arrives at the specified hot metal pan receiving position. No need to wait. In addition, since the hot metal pot is not directly mounted on the transport trolley by the crane, the crane transfers the suspended hot metal ladder to the hot metal ladle setting device without waiting for the arrival of the transport trolley, and immediately performs dephosphorization once. The operation of inserting new untreated hot metal into the dephosphorization converter after the completion of the process can be performed. As a result, the operating efficiency of the crane is increased, and the operating rate of the crane is increased. As a result, the waiting time for charging untreated hot metal into the converter after tapping (included in the cycle time for dephosphorization and decarburization refining) Waste time) can be saved, thereby improving productivity.
