DEVICE, METHOD, AND PROGRAM FOR DETECTING MOLTEN-METAL SURFACE LEVEL IN CONTINUOUS CASTING MOLD

摘要

A heat flux derivation unit (202) derives the value qy of the y-axis component of a heat flux vector. A molten-metal-surface-level derivation unit (203) derives, as a molten-metal surface level, the position of maximum absolute value of the y-axis component value qy of a heat flux vector, the y-axis component vector of which is in the opposite direction from a casting direction.
