Abstract
In order to reduce the deviation of high-temperature deformation detection for metallurgical equipment,a research on high-temperature deformation detection method for metallurgical equipment based on fiber optic sensing technology is proposed.Firstly,the basic principles of fiber optic sensing technology are analyzed,and then the pulse pre-pumped Brillouin optical time-domain analysis method is selected as the fiber optic sensing technology,and the installation and layout scheme design of the fiber optic sensor is carried out.To achieve subsequent deformation detection and ensure the quality of collected data signals,the average method is used for processing.Finally,based on this,the selected fiber optic sensing technology is utilized to complete high-temperature deformation detection of metallurgical equipment.The results show that the proposed method can effectively reduce the deviation of high-temperature deformation detection for metallurgical equipment,and has high detection accuracy.
