れてきた。2. Description of the Related Art To improve productivity in continuous casting,
It is effective to perform a so-called continuous casting operation in which continuous casting is connected by replacing the molten steel ladle. Therefore, in order to facilitate the continuous casting operation, it is important to replace the empty pot and the filling pot. For example, the ladle turning device disclosed in Japanese Utility Model Publication No. 49-138113 and Japanese Patent Publication No. 53-6233. A pan support trolley equipped with the pan exchange trolley shown in FIG. 1 and a pan support pedestal equipped with the pan exchange trolley disclosed in JP-A-54-137434 have been developed.

る。As shown in FIG. 5, the slab obtained by continuous casting operation has a top piece, a bottom piece, and
And the quality level of the unsteady part of the seam piece of continuous casting is low.
The quality of unsteady cast slabs deteriorates when the molten steel ladle is opened. It is considered that this is caused by casting of molten steel in which inclusions are suspended. Among them, the deterioration of the quality of the bottom portion of the slab or the seam portion is caused by the problem of Japanese Patent Laid-Open No. 4-22
As described in Japanese Patent No. 8247, the filling hole filled in the molten steel ladle, that is, the filling sand filled in the tap hole, falls into the tundish and is suspended in the molten steel, or is a constituent component of the filling sand. The main cause is that oxidation of Al and the like in molten steel is caused by SiO 2 , and the oxide is injected from the tundish through the immersion nozzle into the mold to be cast and collected as inclusions in the cast piece. If the injection flow sealing device is not used between the pan and the tundish, if the molten steel is solidified by the injection nozzle and flow rate control device, the injection flow will be disturbed and the molten steel will be oxidized by contact with the atmosphere. It is also considered that the increase in oxides caused by the phenomenon.

鋼凝固を防止することが必要である。As an operating method for reducing the influence of the nozzle filling on the deterioration of the slab quality, Japanese Patent Laid-Open No. 4-228247 has been proposed.
In the gazette, after the filling sand pre-filled in the pouring hole of the molten steel ladle was discharged at a place other than the casting position on the ladle supporting device, the pouring hole was immediately closed, and then the pot was moved to move it on the tundish. A molten steel injection starting method is described in which gas is blown from a closing plate until the injection hole is opened at the casting position. From the viewpoint of slab quality, it is important to prevent the nozzle filling from mixing with the molten steel for casting.However, when the filling is originally a sliding nozzle used as a pouring flow control device, it is easy to open the nozzle at the start of pouring. As described in JP-A-4-228247, when discharging the packed sand at a position other than the casting position on the tundish, the filling hole is closed after discharging, It is necessary to blow gas from the closing plate to prevent solidification of molten steel at the nozzle portion until the start of casting.

ることが可能である。The ladle turning device disclosed in Japanese Utility Model Publication No. 49-138113 is originally a device for mounting two ladle ladles on the turning arm of the ladle support device, and the ladle ladle is exchanged by turning. It is something to do. Therefore, the molten steel ladle can be moved to the ladle mounting position, the standby position, and the casting position without moving the ladle from the ladle supporting position on the ladle turning device, and the ladle ladle can be moved at the molten steel ladle supporting position of the swivel arm. If a device for raising and lowering each independently, a power supply for each pot, and a device for supplying various gases to each molten steel pot are installed, a closing plate will be installed until the molten steel pot is loaded and sand is discharged, and then molten steel is poured into the pot. It is possible to continuously blow gas from the inside to prevent solidification of molten steel at the nozzle portion.

No. 235 gazette, a pan supporting trolley equipped with one pan changing trolley, and a molten steel ladle such as a pan supporting gantry equipped with one pan changing trolley disclosed in JP-A-54-137434. In the support device, it is necessary to move the pan on the molten steel pan support device from the pan loading position to the casting position. Therefore, after discharging the packed sand at the pot loading position, gas is continuously supplied into the nozzle during the movement of the pot from the pot loading position on the molten steel ladle support device to the casting position, and until the start of molten steel injection. This prevents molten steel from solidifying in the nozzle, but it is difficult to do so smoothly.
