Abstract

PURPOSE: To prevent the generation of breakout by detecting mold oscillation electric currents, detecting restraining phenomena, and controlling casting speeds.
CONSTITUTION: When an output signal from an electric current detector 61 detects an abnormal phenomenon, and if the signal which is the voltage value based on the output signal from a pilot generator 32 outputted via an operator 69 in accordance with this increases by having a constant correlation with oscillation electric current, a comparator 67 does not operate. However, if the abnormal phenomenon increases where there are no changes at all, the output signal from an operator 66 goes larger in absolute value than the value of the output signal from the operatr 69 in the comparator 67 and therefore the comparator 67 operates. When there are the operation of said comparator 67 and the operation of a comparator 64, that is, when both of a relay connected to the comparator 67 and a relay connected to the comparator 65 go on, the occurrence of a restraining phenomenon is detected.
