The present invention relates to a casting apparatus for non-ferrous metal sheet material, which can drastically reduce production costs.

In general, the production of non-ferrous metal sheet material is produced by a number of processes from the ingot (smelted in a smelting plant) and a number of machinery for performing the process.

That is, the ingot is melted in a melting furnace to produce a billet, and the billet is manufactured from a metal sheet having a predetermined thickness through hot rolling and cold rolling.

The main task in the manufacturing process of these metal products is to block the outside air (oxygen) to prevent oxidation.

The billet is exposed to outside air (oxygen) at a high temperature state in which bonding with oxygen is promoted, and at the moment when the billet is exposed, the surface is already in an oxidized state, so the scouring removes the oxidized epidermis before proceeding to the next process. (Scabbing) The process is added.

The scouring process is an operation in which the oxidized surface is peeled off using a milling machine while blowing argon (Ar) gas, which is an inert gas, in order to block oxygen contact with nonferrous metals, which requires a large amount of time by skilled manpower. There was a problem in that a variety of cost burden, such as the need to transfer a separate machine and workshop, material to the process location for this purpose.

As described above, the manufacturing of the nonferrous metal sheet of the prior art requires a billet manufacturing process including a melting furnace for billet ingot making process, a scouring process for removing the oxidized surface of the billet, and thus a large scale apparatus and a workshop. And manpower must be involved, and a lot of manpower is required for the management of these facility devices, and in particular, the initial investment cost burden is large, thereby increasing the cost cost of the nonferrous metal sheet.

The present invention has been devised to solve the above problems,

An object of the present invention is to provide a non-ferrous metal sheet material directly through a mold wheel through a molding part including an inert gas supply part, a melting part for dissolving the ingot, a nozzle part for discharging the dissolving liquid, and a mold wheel for dissolving the dissolving solution. Molded and molded to
