ABSTRACT:
A gas flow control system for molten metal molds with permeable perimeter walls, wherein an approximately constant gas mass flow is maintained in individual molds and approximately equal gas mass flows are maintained in molds on the same mold table. A PLC is utilized in combination with a gas mass flow controller to continually monitor and maintain the approximately desired mass flow of gas to the mold cavities.
