And squirts out from the outer peripheral surface of the rotating body 17 to the periphery. Then, a part of the spouted inert gas flows into the basin cover 6 from the gap 8. At this time, the rotating body 17
The gap 8 is closed by the rotating body 17 because it rotates while being in contact with the outer peripheral surfaces of A and 1B and in contact (sliding contact) with the outer surface of the lower end of the side wall 7. Therefore, the outside air is prevented from being drawn into the basin cover 6 from the gap 8, and the oxygen concentration in the basin cover 6 can be reduced. Further, the atmosphere around the outer peripheral surface of the rotating body 17
Also prevented from being drawn into the basin cover 6 due to rotation.

引き込まれることも防止される。 As described above, according to the present invention, a rotating body is provided outside the gap between the basin cover covering the upper part of the molten steel and the outer peripheral surface of the roll, and the outer peripheral surface of the rotator is covered with the basin cover. By making contact with the outer surface and the outer peripheral surface of the roll and injecting the inert gas from the outer peripheral surface of the rotating body, the inert gas is ejected from the outer peripheral surface of the rotating body to the periphery, and at the same time, the outer peripheral surfaces of the basin cover and the roll. Is always closed by the rotating body. Therefore, since the outside air is prevented from being drawn into the basin cover from the gap due to the rotation of the roll, oxidation of the molten steel surface can be prevented and slab cracks can be prevented. Further, the rotating body has a plurality of ejection holes.
And a woven fabric wound around the outer surface of the rotating tube
The inert gas passes through the woven fabric from the outlet of the rotating pipe.
To blow out from the outer peripheral surface of the rotating body,
The atmosphere around the surface is inside the basin cover as the rotating body rotates.
Pulling in is also prevented.
