摘要:
In an automatic molding apparatus, a Doppler speed meter is used to detect the rising speed of molten metal within a mold, and a nozzle stopper attached to a ladle in which the molten metal is contained is actuated in response to a difference between a detected speed signal and a speed pattern signal to control the opening of the nozzle of the ladle whereby the rising speed of the molten metal fed from the ladle to the mold through the nozzle can be controlled in accordance with an optimum molding velocity pattern.
