Abstract: Measuring magnesium alloy’s ignition temperature with a thermocouple had the disadvantages of slow response speed, interfering temperature field, low accuracy, etc, magnesium alloy’s ignition temperature test system based on two-color method was designed, ignition time was located according to inflexion of radiation energy. First, emissivity test experiment was designed, magnesium alloy was heated relaxedly by current heating method, measured value of C-type thermocouple was divided by measured value of high-speed industrial grade infrared ray transmitter OS4000 to determine material’s emissivity, the emissivity at the temperature approximating to magnesium alloy’s ignition value was used to amend measured value of OS4000; after that, magnesium alloy was ignited by current heating method, the relative error between ignition temperature test system’s result and OS4000 result was 2.67 %; at last, in order to improve temperature-measuring accuracy, the emissivity ratio corresponding to two wavelengths at the temperature approximating to magnesium alloy’s ignition value was amended, results show that, temperature-measuring accuracy is 0.76 % after amending.


Keywords: Two-color method, Ignition temperature, Emissivity ratio amendment, Current-heating method, Magnesium alloy.
