Abstract (en)
A casting assembly for controlling melt puddle stability and nozzle degradation in planar flow metal casting operations includes a casting nozzle for receiving and dispensing molten metal from a reservoir. The nozzle dispenses the molten metal through an elongated discharge slot onto a relatively moving chill body. The metal solidifies soon after deposit onto the chill body. The discharge slot is defined by a pair of spaced parallel lips. A manifold is provided in the lips for directing an inert gas through the nozzle to isolate the lips, including the exterior surfaces thereof adjacent to the chill body, from molten metal deposited onto the chill body. A surface glaze impermeable to the inert gas is applied to all external surfaces of the nozzle except the exterior lip surfaces to confine passage of the inert gas to critical areas of the nozzle.
