Abstract
Molten metal is supplied into a mold having an inlet and an outlet opening in such a manner that the molten metal may have a substantially zero pressure at the outlet opening of the mold, while the inner wall of the mold is maintained at a temperature sufficiently higher than the solidifying temperature of the molten metal so that the contiguous surface of the metal remains liquid until it has left the molten outlet. A dummy bar having a temperature lower than the solidifying temperature of the molten metal is brought into contact with the molten metal at the outlet opening of the mold, and moved away from the outlet opening, whereby a solidified body of the metal is formed continuously on the end of the dummy bar.
Claims12
A continuous metal casting process comprising:
- supplying a molten metal into a mold provided with an inlet and an outlet opening in such a manner that the pressure of said molten metal is maintained in the range of 0 to 0.005 kg/cm.sup.2 at said outlet opening, while said mold has an inner wall maintained at a temperature sufficiently higher than the solidifying temperature of said metal so that the contiguous surface of the metal remains liquid while within the mold;
- bringing a dummy bar having a temperature maintained lower than said solidifying temperature into contact with said molten metal at said outlet opening;
- and
- moving said dummy bar away from said outlet opening, whereby a solidified body of said metal is formed continuously on the end of said dummy bar as the metal body leaves the wall opening.
