METHOD AND DEVICE FOR PREDICATION AND CONTROL OF MOLTEN STEEL FLOW PATTERN IN CONTINUOUS CASTING

WIPO Patent Application WO/2000/051762

A1

A molten steel flow pattern control method in continuous casting, comprising the steps of (a) continuously casting molten steel injected from an immersed nozzle, (b) measuring the temperature of a mold longer side copper plate at multiple points in the lateral direction relative to the mold longer side, (c) detecting the flow pattern of molten steel in the mold from a variation in copper plate temperature along with the elapse of time at each measuring point, and (d) controlling the flow pattern based on the detected results so that the flow pattern becomes a specified one, the temperature of the mold copper plate being measured by a plurality of temperature measuring elements buried in the rear surface of the mold copper plate for continuous casting, and the temperature measuring elements being provided in those areas apart 10 to 135 mm from the surface position of molten steel in the mold in the casting extracting direction.
