本文在分析的基础上，研制出了一种新型的应用于铸铁型材水平连铸生产线检测结晶器出口铸坯表面温度的分叉式光纤比色智能化测温仪，并介绍了该测温仪的组成，设计、抗干扰措施及实测结果。该测温仪的研制，为新型智能化比色测温仪的开发提供了一条新途径。 Based on the analysis, this paper developed a new type of bifurcated fiber optic colorimetric intelligent thermometer used in the horizontal continuous casting production line of cast iron profiles to detect the surface temperature of the slab at the exit of the mold. The thermometer The composition, design, anti-interference measures and the measured results. The development of the thermometer provides a new way for the development of a new intelligent colorimetric thermometer.
