[0002] In steel mills, the temperature measurement of LF refining furnaces is generally done manually, and the results of the temperature measurement directly affect the progress of the entire steelmaking process.

[0003] The environmental characteristics of the steel plant are high temperature, high dust and high noise. In addition, the temperature of the LF refining furnace is as high as 1600 degrees Celsius during blowing. Under this circumstance, the staff needs to use special temperature measuring tools to reach into the ladle for temperature detection, so as to obtain the temperature at that moment and location. The temperature measurement result at this time is related to the staff's operation and will affect the efficiency of steelmaking, so a scientific and efficient temperature measurement method is essential.
