題があつた。 However, the above-mentioned conventional ultrasonic vibration mold is configured so that the antinode of vibration of the mold is located at both ends of the mold with emphasis on the resonance of the mold. There was a problem that the break ring, which promotes shell formation and ensures good slab drawing, was damaged by vibration.
