ABSTRACT:
Teeming of molten metal from a laden vessel into a receiving vessel such as an ingot mould or tundish is accomplished at a controlled rate by detecting the changing weight of one of the vessels and deriving a valve control signal by comparing a changing weight signal with a presettable reference signal, the valve control signal being employed to adjust the setting of a sliding gate valve through which molten metal passes as it is teemed into the receiving vessel.
