Abstract
In view of the situation that on-line continuous temperature measurement can not be realized and the cost of thermocouple temperature measurement is high, the infrared dual-light colorimetric temperature measurement method is proposed in this paper. Based on Wien’s formula, a temperature model is established. Through theoretical analysis and experiment to select the appropriate double light wavelength, through laboratory calibration and fi eld calibration proved the feasibility of the infrared double light colorimetric temperature measurement system adopted in this paper, not only can realize online continuous temperature measurement, can realize smelting in strict accordance with the smelting process curve, to ensure the time of steel and the content of each element, it is of great signifi cance to China’s metallurgical industry
