Abstract

PURPOSE:To cast the ingot of fine structure and having no segregation by controlling the thickness of a solid-liquid co-existing layer in a limited thickness in the course of accumulating the droplet of a molten metal inside a mold or on a stool. CONSTITUTION:In case of making a molten metal a droplet by blowing a gas to the molten metal and accumulating this droplet by catching it inside a mold or on a surface plate, the mold having the sectional area wider than the range of the droplet falling or a surface plate is used. And the mold or surface plate is moved simultaneously with the thickness of a solid-liquid coexisting layer within the range A the droplet falls reaching in 15mm. Then, it is accumulated on the part where no droplet is dropped so far. On the other hand, a solidification is progressed by forced cooling with a gas or solid body or a natural. cooling on the part of the range A. The thickness of the solid-liquid coexisting layer can be made always in <= 15mm by repeating the operation.
