BREAK SURFACE CONTROL DEVICE OF DIRECT CHILL CASTING

摘要

an eddy current sensor(7) installed at the upper part of molten metal in a mold; a controller(11) treating a voltage component to linear program; the voltage component being detected by the eddy current sensor and having a functional relation to the height of molten metal; and an actuator(15) for controlling a stopper(6) operated by the output of the controller(11). The apparatus maintains uniformly the height of molten metal poured in a metal mold(4).
