Abstract
A casting apparatus for pouring molten metal into molds comprises a vessel having a molten metal-receiving chamber generally extending between a filling end and a pouring end. The vessel includes a nozzle disposed in a bottom surface of the chamber proximate to the pouring end. A stopper cooperates with the nozzle to control a downward gravity flow of molten metal through the nozzle. A first support pivotably supports the vessel to provide a horizontal tilt axis substantially coincident with the nozzle. A second support is connected to the vessel at a point away from the tilt axis and has a drive for controlling a pivot position of the vessel. A tilt angle controller detects a level of molten metal within the chamber and engages the drive to maintain the level at a predetermined level.
