この発明は、溶融金属用容器の摺動ノズル菱道に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding nozzle for a container for molten metal.
従来、タンディッシュ又は取鋼等の溶融金属用容器の笹
勤ノズル装置は、第１図に示されるように構成されてい
た。Conventionally, a sasagin nozzle device for a container for molten metal such as a tundish or a steel plate has been constructed as shown in FIG.

動ノズルである。In FIG. 1, 1 is an upper fixed nozzle provided on the bottom wall 2 of the vessel for molten metal, 3 is a fixed upper nozzle fixed at the lower part of the upper fixed nozzle 1, and has a closure 4 that matches the upper fixed nozzle 1. Plate 5 is a sliding plate that is slidably attached to the lower part of the fixed plate 3 and has a closing opening 6 that matches the sekiguchi 4 of the fixed plate 3, and 7 is fixed to the lower part of the sekiguchi 6 of the sliding sardine plate 5. It is a lower drinking nozzle.

されるのを防止していた。A gas blowing ring 8 made of a bolus refractory is fixed to the inner circumference of the closing opening 4 of the fixed plate 3, and an inert gas such as argon (~) gas is supplied from the gas blowing ring 8 to the upper part. By blowing into the fixed nozzle, when the upper fixed nozzle 1 is closed by the sliding plate 5, the upper fixed nozzle is prevented from being blocked by solidification of the steel inside the upper fixed nozzle 1.
ところが、上記ガス吹込みリング８は、ポーラスな耐火
物で出来ているので、耐熔損性が低く、固定板３の寿命
低下の原因となっていた。However, since the gas injection ring 8 is made of a porous refractory, it has low fusing resistance, which causes a reduction in the life of the fixed plate 3.

ることに特徴を有する。In addition, bolus refractories tend to cause variations in the amount of ventilation, so the flow rate of the inert gas blown into them becomes unstable, and dust sometimes clogs the upper fixed nozzle 1. The present invention has been made to solve the above problems, and includes an upper fixed nozzle provided on the bottom wall of a molten metal container, and an upper fixed nozzle fixed to a lower part of the upper fixed nozzle. a fixed plate having an opening that matches the fixed plate; a sliding plate that is slidably attached to the lower part of the fixed plate and has a cutout that matches the cutout of the fixed plate; and a fixed plate that is fixed to the lower part of the cutout of the sliding plate. A part of the fixed plate is cut out at the lower end of the opening, and a part of the fixed plate is inserted into the upper corner in the circumferential direction of the sliding nozzle bag. The gas injection ring is made of a refractory material with excellent erosion resistance and has a groove formed therein. The gas blowing ring is characterized in that the gas is blown into the upper fixed nozzle from the joint between the plate and the gas blowing ring.
この発明を実施例により図面を参照しながら説明する。The present invention will be described by way of examples with reference to the drawings.

かな間隙を通って、上部固定ノズル１内に吹込まれる。The difference from the subordinate sliding nozzle device shown in FIG. 1 lies in the structure of the fixed plate 3'. That is, the fixing plate 3' directly in front of the sliding nozzle bag of the present invention has a part cut out at the lower end (or upper end) of the opening part 4', and a part of the fixing plate 3' which is directly connected to the sliding nozzle bag is notched in this notch. It consists of a gas injection ring 8' made of refractory material and fitted together. A groove 9 having a roughly shaped cross section is formed along the circumferential direction in the upper or lower corner of the gas blowing ring 8', and argon (~) gas is injected into the groove 9 from the outside of the fixing plate 3'. Inert gases such as these are introduced. The inert gas introduced into the groove 9 from the outside of the fixed plate 3' is transferred from the groove 9 to the gas blowing ring 8'.
The liquid is blown into the upper fixed nozzle 1 through a small gap formed at the joint 10 between the upper surface of the upper surface and the fixed plate 3'.

な効果がもたらされる。In this case, no joint is provided at the joint between the upper surface of the gas blowing ring 8' and the fixing plate 3'. Inert gas is
Since the air is blown into the upper fixed nozzle 1 from the entire joint, the effect of preventing the nozzle 1 from clogging is high. Therefore, there is no possibility that the upper fixed nozzle 1 will be clogged by solidification of molten steel. Note that since the inert gas is blown into the fixing/zipper 1 from the joint, there is no need to form an inert gas passage in the gas blowing ring 8'. According to this invention, instead of the conventional gas injection ring made of porous refractory material,
By using a gas blow ring with excellent corrosion resistance, the service life of the fixing plate is greatly extended, and the small gap formed at the joint between the top surface of the gas blow ring and the fixing plate can be removed. Since the inert gas is supplied, various useful effects such as being able to stably blow inert gas into the upper fixed nozzle are brought about.
