Occurs, reducing the product yield. Further, when the alloy elements are transferred to the furnace, the alloy elements are oxidized and adhere to the furnace wall, and these remain as trace impurities in the ingot for a long time, or those that are oxidized and floated are cast as slag inclusions. There is also a problem that the quality of the ingot is deteriorated by being caught in the ingot. Furthermore, stirring is performed by gas bubbling, etc. so that the alloy components meet the prescribed component standards,
Since a plurality of blending points are provided so that an alloy composition with a low concentration to a high concentration can be obtained, the entire apparatus becomes complicated and the number of working steps increases, which causes a working error.
