る。2. Description of the Related Art Generally, in hot metal dephosphorization and decarburization work (refining work) at a steel mill, the hot metal that has been dephosphorized by a converter is tapped into an empty hot metal ladle mounted on a carrier, The hot metal ladle containing the hot metal is moved to a predetermined place by the carrier, and the hot metal ladle is lifted by a crane from the carrier and transferred to another converter for decarburizing treatment in the next step. Then, the hot metal in the hot metal ladle is transferred to the decarburizing converter, and the empty hot metal ladle is again transported by a crane to a position above the waiting position of the trolley to be mounted on a transporting trolley, It is carried out again to the tap of the dephosphorization converter. By the way, as shown in FIG.
Fig. 6 shows an example of cycle time when the dephosphorization converter and the decarburization converter as shown in Fig. 1 are arranged in a row in the same building and the dephosphorization and decarburization treatment operations are performed. As shown in Fig. 6, the cycle time of the dephosphorization converter and decarburization converter (one cycle from tapping to the next tapping) takes about 23.5 minutes. , This cycle time is a "useless waiting time", that is, the refining can be completed and tapped until the hot metal ladle that has once been received is emptied again and reaches the bottom of the taphole and is ready for tapping. Nevertheless, there is a wasteful waiting time that it can be kept waiting in the converter. This wasteful waiting time is the state in which the hot metal ladle that has received the hot metal from the dephosphorization converter is carried to the decarburization converter, is charged into the decarburization converter, and is emptied again. This occurs due to the time lag between the time when the steel is returned to the bottom of the tapping port of the converter and the time when the next dephosphorization work is finished in the dephosphorization converter and the tapping is ready again. That is, in the hot metal transfer between the converters with one hot metal ladle and one crane, the hot metal ladle that received the dephosphorized hot metal was transferred by the crane to the decarburizing converter, and then emptied again. The molten hot metal ladle is transported to a carrier truck, mounted on it, and moved again below the tapping port of the dephosphorization converter, so that the decarburization converter is completely charged. Therefore, the next empty hot metal ladle cannot be prepared under the dephosphorization converter until the dephosphorization converter is returned to the dephosphorization converter by the crane and the carrier, and therefore the dephosphorization converter is tapped. This is due to waiting. As an example of such an arrangement, for example, Japanese Patent Laid-Open No.
There is one disclosed in FIG. 1 of Japanese Patent Publication No. 41624/1992, which performs dephosphorization / decarburization work using two converters. These two converters are located in the same converter building, and the trolley for transporting the hot metal pot between the converter back building, the converter building and the converter front building is located under each converter. Rails are laid so that you can travel while passing. Then, in order to transfer the hot metal in the converter after dephosphorization to the hot metal ladle on the carrier, the dolly is moved to the tap hole of the converter, and after the hot metal is tapped into this empty hot metal pot, the hot metal ladle is opened. Is carried by a carrier to a predetermined place and then by a crane to a converter for decarburization. The hot metal in the hot metal ladle transferred is transferred to the decarburizing converter, and then the empty hot metal ladle is again transported to the dolly by a crane and mounted on the dolly, and this dolly is used for the dephosphorization converter. It moves to a predetermined position of No. 1 and the dephosphorized hot metal is again tapped to the hot metal ladle. In this way, for the transfer of hot metal between both converters by one hot metal ladle and one crane,
There is a limit to reducing the cycle time due to the useless waiting time. Incidentally, in the hot metal treatment in the converter, the refining time for dephosphorization and decarburization (blown time) takes about 15 minutes in the above publication, but in the nominal 220t converter, in recent years, The refining work can be completed in about 10 minutes, and the refining time is preferably shorter for the purpose of shortening the cycle time, and it tends to be further shortened in the future. However, in the above-mentioned conventional hot metal ladle transfer device between converters, even if the refining is completed in about 10 minutes, the hot metal ladle being poured into the decarburizing converter is the taphole of the dephosphorizing converter again. The dephosphorization converter cannot tap the iron until it is prepared below, resulting in unnecessary waiting time.Thus, although the refining time was shortened as described above, the cycle time There is a problem that is not shortened.
