PURPOSE: To fully automatically control the operation from the start of a ladle to the start of pinch rollers, in the starting method of a continuous casting apparatus.
CONSTITUTION: In the starting method for the continuous casting apparatus of supplying argon into a sliding nozzle 13 in a tundish 4 and further, executing oscillation control to this nozzle 13, the molten steel is poured into the tundish 4 from the ladle 11, and when the tundish wt. reaches a first set value, the blowing of argon into the sliding nozzle 13 in the tundish and the oscillation of the sliding nozzle 13 are started. Successively, when the tundish wt. reaches a second set value, the sliding nozzle 13 in the tundish 4 is opened to start the pouring of the molten steel into the mold 7.
