The present invention relates to a rotary continuous casting apparatus, and more particularly shows a modification of suppressing scum (Scum) generated during the injection molten metal, so that a beautiful and surface changes in the molten metal surface by injecting a nitrogen or argon gas, generated It is to maintain the level of surface by adjusting the solidification time by using the heat. The driving device is provided on the outside for easy maintenance. It is intended to greatly improve.

As is well known, nonferrous metals are soluble and dissolve when heated to high temperatures. The molten metal is injected into a prepared mold to make an ingot. The process of making this ingot is called casting, and the mold injecting the molten nonferrous metal is cast. mould).

As described above, the apparatus for making a casting is generally known in Korea, and a foreign company, MANNESMANN (DEMAG), has already used a rotary continuous casting machine.

However, the prior art as described above is concentrated to receive all loads in the center, and the thrust ball bearings used do not withstand the impact loads and the uneven loads are generated, resulting in wear and failure rate of the rotating part as well as loads on the outside. Because of this concentration, a problem arises that the bending and leveling are difficult.

In addition, the driving device is installed inside the rotating plate has caused a problem of safety and maintenance uncomfortable.

In the prior art, there is no device for blocking contact with air in the air during injection of a molten metal.

In addition, the prior art also has a problem that the leakage occurs during the rotation of the rotating plate due to the cooling water pipe is buried underground and connected to the distribution cylinder to the upper portion, which caused a significant inconvenience in maintenance .
