| Abstract: | In view of the strategy of high quality and efficiency for vacuum metallurgy and heat treatment processes, the new temperature sensors for vacuum metallurgy are discussed inclnding the possible judging mistakes and problems due to fixed thermocouples used in thermally measuring process in vacuum furnaces. Based on a detailed discussion on the thermometric systems applied to vacuum metellurgy plant especially on the shortcomings arising from discrete allocation of thermometric (elements,) the integrated on-line calibration in site is recommended to improve further the thermometric accuracy. |
