Heating billet temperature cannot be detected in the hearth. Only by detecting temperatures of the stove side or hearth with estimation from mere experience could lead to great error on the measurement of billet temperature and affect the quality of post-processing accordingly; Overheating also exists in the heating process, and the quality of product is sway by overheating oxidation. Though infrared thermoscope is used to detect the temperature of billet when it is taken out of the stove, precision is still affected because of the oxide layer on the surface.
