Abstract: Using thermal imager in hot stamping production enterprises to measure the temperature of steel sheet has the characteristics of high automation, fast response and convenient control. However, in the practical application, infrared temperature measurement generally exists the problem of inaccurate temperature measurement, resulting in the quality of stamping parts cannot be accurately controlled. The main reason for the inaccuracy of temperature measurement is the inability to calibrate the infrared thermal imager and set the correct emissivity. Therefore, this paper analyzed the relationship between emissivity and boron steel sheet temperature, and derived corresponding equations to quantitative define this relationship. The research results indicate that as the sample temperature decreases, the influence of emissivity on the temperature of the thermal imaging instrument gradually decreases. At the same temperature, as the emissivity increases, the display temperature of the thermal imager gradually decreases. Based on experimental testing, the relationship between emissivity and sample temperature is obtained, which is used to correct errors in high and low temperature ranges and improve actual measurement accuracy.
