ABSTRACT:
In this blocking apparatus, at least a portion of the pipe connecting the inlet orifice of the mold to the outlet orifice of the tank containing molten metal is in thermal contact with the mold, which mold includes at least one channel through which a cooling fluid can be caused to flow. Heater means are also associated with the pipe. Thus, the flow of molten metal from the tank into the mold can be stopped by allowing a plug of solidified metal to form in the pipe when the mold is cooled, and the flow of molten metal can be re-established by melting the plug of solidified metal by use of the heater means.
