PURPOSE:To draw out efficiently a continuously cast ingot having fine crystal texture by providing a cooler in the molten metal well part of a vertical type continuous casting device, depositing a seed crystal on the inside wall of a casting mold, detaching the crystal by a mechanical means and feeding the same to a molding part. CONSTITUTION:A cooler 7 is provided as circumscribed to an inside wall 8 in a molten metal well part A in a vertical continuous casting device for an Al billet, etc. The cooler 7 is so disposed that the cooling surface thereof forms directly the inside wall of the part A. A refrigerant is run in the cooler 7 to cool the inside wall 8 of the casting mold in this part so that a crystal is deposited on the wall 8. The crystal is then stripped from the wall 8 by operating a seed crystal stripping means 10 sliding vertically along the wall 8. The stripped crystal is made to arrive at a casting ingot molding part B as the molten metal flows downward. An adequate amt. of the seed crystal is thus easily fed to the solidifying zone of the casting ingot and the continuously cast ingot having uniformly fine crystal texture is obtd. |
