Molten metal 103 is supplied from the nozzle 104 to form a solidified shell 109 by cooling it in contact with the surfaces of the casting drums 101 and 101 to cast a thin metal plate 110.
The structure is such that it is pulled out at a predetermined speed by pinch rolls 107 and sent to the next process.
In addition, in the figure, 102 is a pair of side dams, which are devices for preventing the molten metal 103 from leaking to the outside between the casting drums 101, 101.

When casting a thin metal plate using the conventional casting apparatus described above, when the rotational speed of the casting drum changes (for example, when starting this casting apparatus, immediately after supplying molten metal 103 from the nozzle 104, the casting drum 101 starts rotating, gradually increases the speed, and continues casting until it reaches a predetermined constant speed), the thickness of the release agent coating on the surface of the casting drum changes, making it possible to maintain stability in the casting operation. It can be difficult.

In the present invention, a movable shielding plate installed in front of the spray nozzle for applying the mold release agent,
By moving in accordance with the rotational speed of the casting drum, part or all of the release agent sprayed onto the surface of the casting drum is blocked. This makes it possible to always maintain the optimum amount of release agent applied to the surface of the casting drum.

を変化させることができる。 In FIG. 1, a shielding plate 116 is installed in front of the spray nozzle 111, and a shielding plate 116 is installed in front of the spray nozzle 111.
The mold release agent 1 is sprayed from 1 to the casting drum 101.
Part or all of 15 is shielded. This shielding plate 11
6 is a controller 120 based on a signal from a rotation speed meter 118 that measures the rotation speed of the casting drum 101.
The mold release agent 115 is raised and lowered (moved) as shown by the arrows by the cylinder 117 controlled by the cylinder 117, and the amount of the release agent 115 attached to the surface of the casting drum 101 can be changed by the amount of movement.

一定になるとはじめて厚さ一定となる。 The spray nozzle 111 blows out a fixed amount of mold release agent 115 per hour, while the casting drum 101
For example, when starting casting, the rotational speed is gradually increased from a stopped state, and then becomes a constant speed. Therefore, if there is no shielding plate 116, the casting drum 1
01 Release agent 1 attached to and coated on the surface
15 is thick immediately after the start of casting, gradually becomes thinner thereafter, and becomes constant only when the rotational speed of the casting drum 101 becomes constant.

剤付着量を可能とするものである。 By the way, it is generally said that the amount of mold release agent 115 that adheres to the surface of casting drum 101 should be constant regardless of the rotational speed of casting drum 101. In the present invention, since the shielding plate 116 is moved in accordance with the rotation speed of the casting drum 101 as described above, it is possible to keep the amount of mold release agent 115 attached to the casting drum 101 constant from the start of casting. I can and
Furthermore, it is possible to achieve an optimum amount of mold release agent deposited to stabilize thin metal sheet casting operations.
