置が得られる効果を有している。[Effects of the Invention] As described above, according to the present invention, the casting melting method is performed by tapping the molten metal, which has been subjected to component adjustment, reforming treatment such as deoxidization and degassing, and molten metal treatment such as slag removal, to solidification. After the raw material is made into a rod or coil shape and sized to the required dimensions, it is fed and melted in an inert atmosphere using a non-gas generating melting method, and the melted raw material is tapped and put into a mold. In addition, the casting and melting equipment is used to pour molten metal into rod-shaped or coil-shaped molten metal, which is formed by tapping and solidifying molten metal that has undergone component adjustment, reforming processes such as deoxidization and degassing, and molten metal processing such as slag removal. There is a sizing device for sizing raw materials to required dimensions, and a closed container is maintained in an inert atmosphere, and a non-gas generating heating device is housed inside, and the non-gas generating heating device is used for sizing. The above-mentioned sized raw material is lifted so that it can be fed, and it is equipped with a melting device that has a molten metal pool at the bottom that does not communicate with the tap outlet, so the casting quality can be adjusted by composition. Effects of providing a casting melting method and device that can improve the quality of the melted metal, including the above, and efficiently obtain a good quality molten metal in a short time without deteriorating after melting, and also maintain the surrounding environment in a good condition. have.
