However, the raw materials for each metal to be supplied are solids, and the dissolution rate and diffusion in the melting furnace are different. Therefore, when the raw materials for each metal are supplied to the melting furnace, the concentration distribution and temperature distribution of alloy components in the melting furnace will be uneven. However, there was a problem in that the components of the molten alloy supplied to the holding furnace became non-uniform, making it impossible to continuously cast a long body of stable quality. In addition, with conventional equipment, it is not possible to add new raw materials during continuous casting, so in order to increase the length with conventional equipment, the size of the melting furnace must be increased to increase the amount of alloy that can be melted at one time. This created a problem in that the entire device became larger.

Then, when the alloy components in one melting furnace are used up, it is possible to switch to another melting furnace and continue continuous casting. In this way, since casting can be performed while reliably controlling the alloy components in each melting furnace, it is possible to continuously cast a long body having stable quality along its length.
