METHOD FOR ESTIMATING SLAB TEMPERATURE IN CONTINUOUS CASTING, METHOD FOR ESTIMATING COAGULATION COMPLETION STATE OF SLAB, AND METHOD FOR CONTINUOUS CASTING
Document Type and Number:
WIPO Patent Application WO/2013/094194
Kind Code:
A1
Abstract:
The present invention assumes a method for estimating a slab temperature by which the slab temperature is estimated using a thermal transfer calculation. The present invention comprises: an ultrasonic sensor which detects the passing of a coagulation completion position of a slab; coagulation completion position moving means which moves the coagulation completion position of the slab from an upstream side toward a downstream side (or from a downstream side toward an upstream side) with respect to the position detected by the ultrasonic sensor; a thermometer which measures a surface temperature of a slab position where the ultrasonic sensor detects the coagulation completion position; and
a parameter modifier which modifies at least one parameter value of parameters used in the thermal transfer calculation by matching a temperature value calculated at a central portion in a slab thickness direction with a solidus temperature or by matching a surface temperature of the slab with a temperature measured by the thermometer at the slab position where the ultrasonic sensor detects the coagulation completion position.
