CONTROLLING MEANS FOR METAL CASTING INSTALLATIONS |
摘要 |
A foundry installation control device is disclosed for causing a rapid cut off of a molten metal flow at the time when a mold is full. Two detectors are provided, one of which collects information concerning the instantaneous rate of metal flow pouring from a ladle into a sprue cup while the other collects information on the level of the molten metal in the cup. An electronic circuit connected to the outputs of the two detectors produces a mold filling signal which undergoes a sharp fluctuation at the precise moment when filling is completed. This signal is compared with an instruction value and causes the generation of a flow cut-off signal which triggers the cessation of pouring by righting of the ladle in the case of a tilting ladle, closing of the stopper in the case of a bottom-pour ladle, or closing the discharge valve in the case of a pressure ladle. |
