In continuously casting molten steel at least a pair of rolls is disposed near the leading end of the crater at which solidification of the molten steel in the cast piece completes so as to roll the cast piece at a reduction rate of from 0.1 to 2.0%. The variation in the thickness of the cast piece is detected and compared with a definite reference value for controlling the drawing speed and or the quantity of the secondary cooling water.
