造機が開発さり、た。In recent years, instead of the so-called vertical continuous casting machine that draws the molten steel from the tunnel downwards, a casting nozzle has been installed horizontally at the bottom of the side wall of the tunnel, and the mold is inserted into the nozzle, mainly for the purpose of reducing construction costs. A so-called horizontal continuous casting machine was developed in which the molten steel in the tundish is poured into the mold through the nozzle, and is drawn out while being cooled.

テなっていた。Conventionally, in the above-mentioned horizontal continuous casting machine, for example, the remaining melt and slag in the tundish tunnel at the end of casting can be removed by using a plug attachment/detachment mechanism provided in the tundish to remove the plug fitted into the bottom wall of the tundish. It turned out that I had to remove the bottom wall as well.

A discharge nozzle for discharging molten steel and slag remaining in the tundish 3, 5 a plug fitted into the discharge nozzle 4, and 6 attached to the side wall of the tundish at the bottom of the discharge nozzle 4. The discharge gutter 7 is a cylinder mounted horizontally by having its base end pivoted on the tandy/yu trolley 1, and 8 is a cylinder 70 with a louver whose one end is pivoted on the tip of the rod 9. , a substantially central portion of the louver 8 is supported by a shaft 10.

グ５の後端が軸着されている。Reference numeral 11 indicates an L-shaped second lever supported by a shaft 12 at a distance from the second lever 8, and 13 connects the curved end of the second lever 8 with one end of the second lever 11. 1st link,
14 has one end pivoted to the curved end of the second lever 11 f
'L' is the second link, and the rear end of the flag 5 is pivoted to the other end of the second link 14.

めである。When the flag 5 is inserted into the discharge nozzle 4, the shaft support on the shaft 12 side of the first link 13, the shaft 10 of the first lever 8, and the shaft support between the first lever 8 and the first link 13 are aligned. They are lined up on a line. This means that when pulling out the plug 5 from the 4 non-ejecting nozzles 4, a large force is required to remove the plug 5.
Once the plug 5 is removed from the discharge nozzle 4
This is to enable the second lever 11 to be rotated by a large amount by only slightly rotating the first lever 8 after removing the junk. That is, the flag 5 can be easily removed, and the plug 5 can be quickly removed after being removed.
This is to enable the discharge nozzle 4 to be moved away from the discharge nozzle 4.

かもたらされる。At this time, the plug 5 quickly moves to a position away from the discharge nozzle 4, so that molten steel and slag do not get caught in the plug 5 and its bending mechanism. □As explained above, according to the present invention, there is no need to install a plug attachment/removal mechanism for each tandy, and there is no need to provide a large space below the tandy, so the equipment cost can be significantly reduced. □Can be reduced. In addition, since the plug is attached to the side of the tundish, the mechanism for attaching and detaching it is relatively simple, and there is no risk of the molten J1111 or slag being scattered around. No. 9. It becomes impossible to remove the plug as it is impossible to remove the plug due to the dregs of the union.
