ABSTRACT:
A valve combination is provided for controlling the flow of liquid metal through an orifice. The valve combination includes an electromagnetic flow control device and an on/off valve. The on/off valve includes an electrically conductive slider plate which is positioned sufficiently close to the electromagnetic flow control device to be inductively heated by the electromagnetic field generated thereby. The on/off valve permits the flow of liquid metal to be selectively stopped and started as desired. The valve combination is suitable for use with open pour and shrouded continuous casting or vessel pouring operations.
