Abstract
A method is disclosed for making thixotropic metal products by continuous casting by pouring liquid metal into a mold with a movable end and having upstream and downstream portions. The upstream portion has a wall made of a heat insulating material at least at its inner surface to form a hot zone, and the downstream portion has a wall made at least partially of a heat conducting material to form a cold zone. A movement is imparted to the solidifying liquid to cause circulation between the cold zone and the hot zone in order to bring about surface remelting of crystals formed in the cold zone and degeneration of dendrites.
