<P>PROBLEM TO BE SOLVED: To provide a steel material temperature measurement method and a steel material temperature measurement device that can measure a surface temperature of a steel material by non-contact even in the presence of mist, steam and dust. <P>SOLUTION: The steel material temperature measurement method includes: a radiation wave detection step for detecting an electromagnetic wave belonging to a micro wave-millimeter wave band of radiation waves radiated from the steel material after the lapse of time required for growth of a magnetite layer having more than thickness corresponding to a state in which the size of the radiation electromagnetic wave belonging to the micro wave-millimeter wave band and a surface temperature of the steel material becomes a linear relationship on the surface of the steel material; and a temperature calculation step for calculating the surface temperature of the steel material from the size of the detected electromagnetic wave belonging to the micro wave-millimeter wave band using correlation relationship information showing a correlation relationship between the size of the radiation electromagnetic wave belonging to the micro wave-millimeter wave band and the surface temperature of the steel material, which is generated in advance, and the size of the electromagnetic wave belonging to the detected micro wave-millimeter wave band. <P>COPYRIGHT: (C)2013,JPO&INPIT |
