Abstract: A start-up system for a continuous casting mold level control system which uses the control signal to detect the onset of casting and in response thereto, energizes the drive motors and alters, for an initial predetermined short period, the control signal fed to the drive motor controls to speed up the withdrawal of continuous billet for that period. Thereafter it automatically restores the control system to normal operation.

Abstract: A molten metal continuous casting mold level control system is disclosed employing an inductance detector positioned within a water cooled continuous casting mold. The detector is mounted in the jacket of the mold about the generally hollow cylindrical mold core which core includes an electrically conductive form having a billet shaping surface. The output voltage from the detector is bucked against a signal that is related to an input signal, filtered and amplified to derive a signal whose polarity from a reference level and magnitude are proportionate to the direction and magnitude of change in the steel level. This signal is used to control the billet drive to correct changes from the desired level.
