For multi-metal (two and more) bath melting, if the two metals are immiscible and the volume ratio reaches 8: 1 or more, even if the metal with a low content is reduced, it is difficult to smoothly discharge the metal due to the restriction of the structure of the conventional molten bath, so that the mixed melting cannot be performed. For example: when the iron-lead ratio reaches 10: at 1, lead is hardly released.
