and an improvement in a suction head forming a second annular nozzle.

た。 Conventionally, in order to cool and solidify slag using the suction head, as shown in FIG. The structure is such that most of S is turned into slag, and cooling water W 2 is injected from the second annular nozzle 7 to prevent slag from adhering to the inner cylinder of the suction head and to completely turn the slag into slag. However, if a large amount of slag is sucked, for example immediately after slag suction starts or when the suction head is too close to the molten metal, the cooling function deteriorates and granulation due to cooling of the slag tends to become unstable. There was room.
本発明の目的は、上記実情に鑑みて、大量のス

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 suction of a large amount of slag, and that sufficient slag cooling can always be performed stably.
本発明の特徴構成は、スラグ吸入口を形成する

とが判つた。 In other words, various experiments were conducted to confirm the state of slag cooling within the suction head when a large amount of slag is sucked, and the following facts were found. That is, as shown in FIG. 3, as a large amount of slag is suctioned, the suction air flow path width d becomes narrower than the normal width d0 , so the speed of the suction air flow A increases rapidly, and the slag flow S Water W 1 is ejected from the first annular nozzle 5 in a film shape in order to supply water evenly over the entire circumference of the slag. It was found that the angle of incidence O with respect to the flow S was much smaller than the normal angle O 0 and that the slag flow S could not reach the interior sufficiently. Furthermore, even if the speed of water ejected from the first annular nozzle 5 is increased, the suction air flow A
It was found that the influence of the cooling performance was large and that the cooling performance could not be improved much.

行えるようになつた。 Therefore, as shown in FIGS. 1 and 2, when a plurality of small holes 14 are provided in the cylinder 4, for example, even if the amount of suction slag increases, the cooling water from the small holes 14 will not flow.
Since W 3 is rod-shaped, it was found that it fully reaches the center of the slag flow S with almost no change in the ejection direction due to the suction air flow A, and as a result, even when the amount of suction slag increases, the Due to the synergy of the uniform cooling effect of the single annular nozzle 5 and the reliable cooling effect of the small hole 14 at the center of the slag flow,
The second annular nozzle 7 prevents slag from adhering to the inner cylinder of the suction head, and the suction slag can be reliably cooled to a state where the slag can be completely turned into slag, ensuring good slag granulation at all times. Now I can do it.
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.
