APPARATUS FOR HIGH SPEED CONTINUOUS CASTING
First Claim
1. Apparatus for the continuous casting of molten metal comprising a rotatable casting wheel having a peripheral casting groove formed therein, an endless flexible band closing a portion of said groove to define a mold therewith, means for tangentially removing said band from said wheel at a given point after the molten metal has partially solidified to expose the outer surface of the metal, means for maintaining the partially solidified metal in said groove for a predetermined arc of travel about said wheel from the point of band removal to an extraction point, means disposed adjacent said wheel between said points of band removal and extraction for applying fluid coolant directly on the exposed outer surface of the metal in said groove for completing the solidification thereof, and wherein said means for applying fluid coolent includes an arcuate spray manifold adapted to emit a plurality of substantially radially directed fluid jets against the outer surface of the metal in said groove.

Abstract
A high speed continuous casting apparatus and method wherein the method includes partially solidifying a molten metal in a mold defined between the peripheral groove of a rotating casting wheel and a flexible band until the metal shrinks and draws away from the casting wheel, thereupon removing the band from the casting wheel and subsequently cooling the metal to complete its solidification. The apparatus includes the combination of a casting wheel having a peripheral groove with a portion of its length closed by an endless band to form a casting mold and an auxiliary cooling means for cooling the metal to complete its solidification. This allows the casting wheel to be rotated at that rotational speed which causes the metal to pass from the casting wheel as, or shortly before or after, the metal shrinks away from the casting wheel, and as a result provides casting rates not achieved with prior art casting wheels.
