Method and apparatus for deciding heated state of metal billet

摘要

A heated state-deciding apparatus and a thermocouple provided for a transport robot for detecting the temperature of a billet being transported by the transport robot, and a deciding member for deciding whether or not the billet is heated to be in a predetermined solid phase state on the basis of the detected temperature. Accordingly, it is possible to efficiently and accurately decide whether or not the solidus rate of the metal billet is good or bad, and it is possible to improve the productivity.
