  • Method for estimating and controlling flow pattern of molten steel in continuous casting and apparatus therefor
    Patent number: 6712122
    Abstract: The method for controlling flow pattern of molten steel in continuous casting, comprises the steps of: (a) continuously casting a molten steel injected through an immersion nozzle; (b) measuring temperatures of a copper plate on longer side of the mold in width direction thereof at plurality of points; (c) detecting a flow pattern of the molten steel in the mold based on the time-sequential variations of temperatures of the copper plate at individual measurement points; and (d) controlling the flow pattern to establish a specified pattern on the basis of the detected result. The temperatures of mold copper plate are measured by plurality of temperature measurement elements buried in the rear face of the mold copper plate for continuous casting. The temperature measurement elements are arranged in a range of from 10 to 135 mm distant from the melt surface in the mold in the slab-drawing direction.
