APPARATUS FOR PREVENTING NOZZLE CLOGGING, APPARATUS FOR CONTINUOUS CASTING HAVING THE SAME, METHOD FOR PREVENTING NOZZLE CLOGGING AND METHOD FOR CONTINUOUS CASTING USING THE SAME |
摘要 |
<p>The present invention relates to an apparatus for preventing nozzle clogging, which rapidly estimates the degree of nozzle clogging when molten steel is supplied from a tundish to a mold and then controls a casting state according to the estimation result, an apparatus for continuous casting having the same, a method for preventing nozzle clogging and a method for continuous casting using the same. The present invention includes measuring backpressure of inert gas supplied to a casting nozzle in real time; and calculating a nozzle status index from the measured actual backpressure. There are effects in that it is possible to rapidly and accurately estimate the location and degree of nozzle clogging based on a backpressure change of inert gas supplied to a casting nozzle, to detect leakage of the inert gas, and to improve a casting yield and quality of strands by suitably controlling inert gas supplied to a casting nozzle.</p> |
