Ｂの吸引に伴つて不十分になり、スラグの冷却に
よる粒状化が不安定になりやすく、改善の余地が
あつた。 Conventionally, to form the suction head, the mouthpiece 2 forming the slag suction port 1 was formed into a cylindrical body having an annular and flat tip surface 2a, as shown in FIG. , water jetted from the annular nozzle 5 inside the mouthpiece 2
The cooling of the sucked slag flow S by W 1 became insufficient as the lumpy slag B was sucked, and the granulation due to cooling of the slag tended to become unstable, so there was room for improvement.
本発明の目的は、上記実情に鑑みて、塊状スラ
グ吸引によりスラグ冷却機能が低下せず、常に安
定して十分なスラグ冷却を行えるようにする点に
ある。 In view of the above-mentioned circumstances, an object of the present invention is to ensure that the slag cooling function is not deteriorated due to lumpy slag suction and that sufficient slag cooling can always be performed stably.
本発明の特徴構成は、溶湯上のスラグに対する
吸入口を形成するマウスピースに、その外周面か

用効果は次の通りである。 The characteristic configuration of the present invention is that a plurality of ventilation holes are formed in the mouthpiece that forms the suction port for the slag on the molten metal, extending from the outer circumferential surface to the inner circumferential surface of the mouthpiece and distributed in the circumferential direction of the slag suction port. The functions and effects are as follows.
つまり、塊状スラグがマウスピースに吸着した
時に、サクシヨンヘツド内でのスラグ冷却状態が
どのようになるのかを、種々実験して確認したと
ころ、下記のような事実が判明した。 In other words, we conducted various experiments to confirm how the slag is cooled in the suction head when the lumpy slag is adsorbed to the mouthpiece, and the following facts were found.
すなわち、第４図に示すように、スラグ吸入口
１の一部が塊状スラグＢで閉じられるため、吸引

に対する冷却水供給割合が、高速空気偏流域側で
多くてそれとは反対側で少くなるように不均等に
なり、吸引スラグ流Ｓのうち塊状スラグＢが吸着
された側の冷却が不十分になる現象が確認でき
た。 That is, as shown in FIG. 4, since a part of the slag suction port 1 is closed by the lumpy slag B, a high-speed suction air flow A is generated that is biased to one side with respect to the suction slag flow S, and the air is drawn from the annular nozzle 5. Among the slag cooling water spouting regions, the high-speed air bias region has a lower static pressure than the other regions, and due to the pressure difference, the flow state of the slag cooling water jetting changes, and the suction slag flow S
The cooling water supply ratio becomes uneven, with more on the side of the high-speed air bias region and less on the opposite side, and cooling of the side of the sucked slag flow S where the lumpy slag B is adsorbed becomes insufficient. The phenomenon was confirmed.
そこで、第１図に示すように、マウスピース２

て行えるようになつた。 Therefore, as shown in Figure 1, the mouthpiece 2
A plurality of vent holes 14 are formed in the slag slag B so that even if a part of the slag suction port 1 is closed by the slag B, the air from the vents 14 is sufficiently sucked into the back of the slag B. , suction slag flow S
It is now possible to reliably maintain good slag cooling by uniformly supplying cooling water W 1 over the entire circumference from the annular nozzle 5 surrounding it, and it has become possible to always and stably granulate the slag.
次に、第１図及び第２図により実施例を示す。 Next, an example will be shown with reference to FIGS. 1 and 2.

流Ａにより搬送するように構成してある。 To configure a suction head connected to a suction device via a granulated slag separator or the like, a mouthpiece 2 forming a slag suction port 1 is attached to an outer cylinder 3, and the mouthpiece 2 and a deep-spreading cylinder 4 attached to it are assembled. A first annular nozzle 5 is formed between the inner cylinder 6 and the deep-spreading cylinder 4, and a second annular nozzle 7 is formed between the inner cylinder 6 and the deep-spreading cylinder 4, so that the suction slag flow S from the suction port 1 can be The slag cooling water W 1 is jetted from the first annular nozzle 5 and the slag cooling water W 2 is jetted and supplied from the second annular nozzle 7 to granulate the slag by cooling and solidifying it. It is configured to be conveyed by suction air flow A.

0, the first and second annular nozzles 5, 7 are connected to each other through the flow path 12 formed between the cylindrical body 8 and the cylindrical shutter 11, the gap between the shutter 11 and its seat 13, etc.
A water supply waterway 9 is connected to.

ほぼ均等に供給できるようにしてある。 A large number of ventilation holes 14 are formed in the mouthpiece 2, extending from the outer circumferential surface to the inner circumferential surface thereof, and are distributed in the circumferential direction of the suction port, so that when the slag on the molten metal is sucked, a part of the suction port 1 is formed by the lumpy slag B. Even if it is closed,
The structure is configured such that air from the vent hole 14 is sufficiently sucked into the back of the lumpy slag B, thereby suppressing an increase in the flow velocity difference of the suction air A around the suction slag flow S, and The slag cooling water W 1 from 5 can be supplied to the suction slag flow S almost evenly over the entire circumference.
