この考案は、連続鋳造機のタンデイツシユへ取
鍋側のロータリノズルから溶湯を注入する際、そ
の注入流を空気からしや断するロータリノズルと
タンデイツシユ間の注入流シール装置に関するも
のである。[Detailed description of the invention] This invention is an injection flow sealing device between the rotary nozzle and the tundish that cuts off the injection flow from air when molten metal is injected into the tundish of a continuous casting machine from the rotary nozzle on the ladle side. It is related to.
従来、取鍋側のロータリノズルとタンデイツシ
ユの間において注入流が空気に触れないようにす
るには、ノズルをロングノズルとするか、取鍋と
タンデイツシユの間をシールボツクスに形成し、
内部に不活性ガスを吹込むようにしていた。 Conventionally, in order to prevent the injection flow from coming into contact with air between the rotary nozzle on the ladle side and the tundish, the nozzle was made long or a seal box was formed between the ladle and the tundish.
Inert gas was blown into the interior.
しかるに、前者においては、ロングノズルの取

ルを折つて洗滌しなければならないため、その後
のシールが出来ない問題があつた。 However, in the former case, the long nozzle installation method is complicated, and air entrainment occurs from the long nozzle attachment point, so preventive measures are required, and once air entrainment occurs, there is no way to detect it. Moreover, if the nozzle becomes clogged, the nozzle must be broken and washed, which poses the problem that subsequent sealing cannot be performed.
また後者においては、ノズル側に空隙が多くシ
ール性が悪い上、タンデイツシユ側のシールボツ
クスが大きくなり作業性が悪く、特にノズルが詰
つた場合に取鍋を上昇しないとノズルの洗滌がで
きない等の問題があつた。 In addition, in the latter case, there are many voids on the nozzle side and the sealing performance is poor, and the seal box on the tundish side is large, making it difficult to work.In particular, if the nozzle becomes clogged, the ladle must be raised to clean the nozzle. There was a problem.
この考案は、上述の観点に基き、取扱いが容易

る。 FIG. 1 shows an embodiment of the device of this invention in a longitudinal sectional side view, and FIG. 2 shows a sectional view taken along the line of FIG. 1. As shown in the drawing, the device of this invention includes a lower cylinder 3 which can be freely covered with the molten metal inlet 2 of the tundish 1, and an upper cylinder which can be freely placed on the lower cylinder 3. 4, and a large opening 4A is provided at the front of the upper cylinder 4.
開口部４Ａは取鍋５側のロータリノズル６の洗
滌を行なえるように設けた開口部であつて、常時
は蓋板７で閉じてある。 The opening 4A is an opening provided so that the rotary nozzle 6 on the side of the ladle 5 can be washed, and is normally closed with a cover plate 7.
蓋板７は例えば複数のボルト８で上部筒体４に
取付けておくが、気密シールが確実であれば、抜
差自在の構造としてもよい。 The cover plate 7 is attached to the upper cylinder body 4 with, for example, a plurality of bolts 8, but it may have a structure that can be inserted and removed as long as the airtight seal is ensured.
タンデイツシユ１と下部筒体３との接触面間に
はシール材９Ａ，９Ｂを介在させてあり、また、
下部筒体３と上部筒体４との接触面間にもシール
材９Ｃを介在させてある。 Sealing materials 9A and 9B are interposed between the contact surfaces of the tandy dish 1 and the lower cylinder body 3, and
A sealing material 9C is also interposed between the contact surfaces of the lower cylindrical body 3 and the upper cylindrical body 4.
一方、下部筒体３の下部には複数の不活性ガス
の吹込口１０を設けてあり、これら吹込口１０に
は不活性ガス導管１１を接続してある。 On the other hand, a plurality of inert gas inlets 10 are provided in the lower part of the lower cylinder 3, and inert gas conduits 11 are connected to these inert gas inlets 10.
また、ロータリノズル防熱板１２には上部筒体

侵入を防ぐ構造としてある。 In addition, a banner 13 made of non-combustible fabric is attached to the rotary nozzle heat shield plate 12 so that the lower edge reaches below the upper end of the upper cylinder 4. Although the outflow of gas is not obstructed, the structure is designed to prevent air from entering as the molten metal 14 flows down.
なお図中符号１５は不活性ガス供給管を示す。 Note that the reference numeral 15 in the figure indicates an inert gas supply pipe.
この考案は上述の構成としたので、タンデイツ
シユ１上に下部筒体３を載置してタンデイツシユ
の溶湯注入口２を掩蔽したのち、上部筒体４を下
部筒体３上に載置する。 Since this invention has the above-described structure, the lower cylinder 3 is placed on the tundish 1 to cover the molten metal inlet 2 of the tundish, and then the upper cylinder 4 is placed on the lower cylinder 3.
一方、垂幕１３は防熱板１２に予め取付けてお
いてもよいし、あとから取付けてもよい。 On the other hand, the banner 13 may be attached to the heat shield plate 12 in advance or may be attached later.
このとき、開口部４Ａを蓋板７で閉じておくこ
とは当然である。 At this time, it is natural to close the opening 4A with the cover plate 7.
