入力によることもある。(Prior Art) FIG. 2 shows a schematic explanatory diagram of a stopper device for a tundish dish, which is the object of the present invention. 1 is a tundish, 2 is a stopper rod, 3 is a horizontal arm connecting the stopper rod 2 and its lifting shaft 4, 4 is a shaft for lifting the stopper rod, 5 is a frame attached to the side of the tundish, 6 and 7 are shafts. It is a slide guide. A rack 8 is cut into the shaft 4, and the teeth of a fan-shaped pinion lever 9 are engaged with the rack 8, and the shaft 4 is raised by pushing down the handle 9' of the pinion lever. The pinion lever is fixed to a fixed frame 10 so that its lever fulcrum can rotate freely. Its operation is based on the hydraulic cylinder 12',
It may also depend on the input.

トと共に自重で降下して、ノズルを塞ぐ。 The stopper rod 2 is raised to open the nozzle at the start of casting. After that, it will be left open for quite a long time (1 to 30 hours) until the casting is finished, so the pin 11 biased by a spring will fit into the keyway attached to the shaft 4, as shown in Fig. 1b. Enter and lock the shaft in the raised position. When closing the nozzle, press pin 11, for example lever 1.
When 1' is lowered and removed, the stopper rod descends under its own weight along with the shaft and blocks the nozzle.

とストツパー装置がついている。(Problems to be Solved) In continuous casting of steel, generally five to eight tundishes are prepared for one continuous casting machine. One unit is in operation and the rest are for preparation and backup. In addition, in the case of bloom casting, one continuous casting machine casts into two to four molds, so the tundish is equipped with the same number of casting nozzles and stopper devices.

装置が求められていた。 As mentioned above, the stopper device targeted by the present invention uses a hydraulic cylinder to push down the pinion lever 9 at the time of opening.
The pros and cons of semi-permanently attaching hydraulic cylinders to all stoppers were considered. That is, if the hydraulic cylinders can be made removable, the number of hydraulic cylinders that can be maintained can be reduced to one tundish. For example, if the number of tundishes is 7 and each tundish has 3 nozzles, a total of 21 hydraulic cylinders would be required, but if the tundishes are removable, only 3 will be required, which reduces equipment costs. is cheap. Therefore, there has been a need for a stopper lifting device that can be easily attached and detached.
