Study on Ultrasonic Radar in Deformation Detection of Carbon Roaster
Aiming at the problem of creep of fire passage wall of carbon roaster in high temperature environment,a deformation detection algorithm applied to fire passage wall is proposed,and the temperature compensation method is used to reduce the influ-ence of ambient temperature on ultrasonic wave velocity.According to the unstable data collected by ultrasonic radar,a filtering algorithm for ultrasonic ranging is designed.The filtered irregular data points are divided into different curve segments,fitted by least square method,and further compared with lidar.The ultrasonic distance measuring platform is used to conduct deformation detection experiments in the roasting workshop.The results show that the algorithm used in non-contact measurement of roasting furnace deformation can provide accurate wall deformation.
