ABSTRACT:
Method and apparatus for automatically controlling the pouring of molten metal into a series of closed casting molds is disclosed. Molten metal flows in a stream from a lip-pour or bottom-pour casting ladle into a pouring gate at the top of a mold and partially fills the gate. Visible light or infrared radiation is emitted from the metal surface in the gate and is detected by a sensing device. The sensing device generates a signal which is a function of the radiation received, and therefore the apparent area of the surface of metal in the gate. The signal operates a ladle control mechanism to control the flow rate of the stream to keep the gate level substantially constant during pouring.
