[0032] When the converter steelmaking end point temperature detection device is used, specifically as follows Figure 1 and Figure 5In the middle, with the dual-color pyrometer spectral acquisition system, the collected flame area can be ideally imaged on the optical surface of the transmission optical fiber, and the spectral distribution in the wavelength range of 345 nm to 1100 nm is obtained. According to the spectral distribution characteristics of the internal slag, molten steel, and refractory lining of the converter tapping hole, the observation of the blowing process of several heats and different steel grades and the calculation and measurement of the spectral light intensity of the characteristic wavelength are carried out.
