METHOD FOR PREDICTING TEMPERATURE OF MOLTEN STEEL IN CONTINUOUS CASTING PROCESS

摘要

The present invention relates to a method for predicting the temperature of molten steel in a continuous casting process. The method for predicting the temperature of molten steel in a continuous casting process includes: a step of calculating surface radiant heat loss of molten steel injected into a raddle storing and transferring molten steel in a continuous casting process through the following formula 1; a step of calculating loss of convention heat generated from a wall of the raddle through the following formula 2; a step of calculating the amount of the molten steel injected into a tundish from the raddle through the following formula 3; a step of calculating the heat energy change of the molten steel in the raddle by substituting the following formula 1, formula 2, and formula 3 in a relation; and a step of controlling the temperature of the molten steel by predicting the temperature of molten steel discharged from the raddle based on the calculated heat energy change of the molten steel in the raddle.;COPYRIGHT KIPO 2014
