<p>A method of controlling a molten steel flowing pattern in a continuous casting, comprising (a) a step of continuously casting molten steel ejected from an immersion nozzle, (b) a step of measuring temperatures at a plurality of points of a mold longer-side copper sheet in a longer-side width direction of the mold, (c) a step of detecting a molten steel flowing pattern in the mold from changes with time of copper sheet temperatures at respective points, and (d) a step of controlling a flowing pattern to be identical with a preset pattern based on the detection result. Mold copper sheet temperatures are measured with a plurality of temperature detecting elements buried in the rear surface of a continuous casting mold copper sheet. The temperature detecting elements are provided within a range 10 to 135 mm away from the molten steel surface in the mold in a billet pulling-out direction.</p> |
