Abstract
A primary object of this invention is to provide a method for operating a continuous casting machine with which a mold can oscillate with a predetermined oscillation waveform since the start of operation of an oscillator. This invention is a method for operating a continuous casting machine, the method comprising: withdrawing a slab from a mold while vertically oscillating the mold with an oscillation waveform represented by the following formula (1) by selecting a value of φ according to a value of b so that the following formula (1) satisfies r(0)=0:()=(/2){sin(ω+φ)+cos 2(ω+φ)+  (1)where r(t): displacement of the mold (mm), S: vibration stroke of the mold S (mm), ω: angular velocity (=2πf) (rad/s), f: oscillation frequency of the mold (Hz), t: time(s), φ: initial phase (°), and b: non-sine coefficient (0<b≤0.25).
