ABSTRACT:
A level control system controls the level of molten metal in continuous or semi-continuous casting equipment, for example casting equipment for production of roll ingots or billets of aluminum. The casting equipment includes a casting mold with an upper open filling hole for receipt of molten metal from a supply gutter or the like having an outlet above the filling hole. The level of the metal is controlled by a PLC unit as a function of a signal from a radar sensor which detects the level of the metal as the metal supply is controlled by a closing arrangement regulated by an actuator as a function of signals from the PLC unit.
