らしめる所以となる。In the apparatus of the present invention, not only the metal is reliably blown away as described above, but also the downward inclination of the hearth (9) causes the molten metal to flow over the hearth (9) under its own weight toward the side wall (1). 3
) direction, and therefore the hearth (9) always maintains the aspect of a dry hearth, there is no chance of solid-liquid contact between the insoluble matter remaining on the hearth (9) and the flowing molten metal. The time required for this process is extremely short, and this is the reason for maximizing the metal blowing effect.
