Laser ranging-based deformation monitoring of coke oven buckstays

Abstract

Buckstay deflection is one of the key indicators for assessing the condition of the battery bracing system, making its monitoring crucial in daily production. In this study, a laser ranging-based deformation intelligent monitoring system for coke oven buckstays was developed. By integrating measurement robots and laser rangefinders, the system enables real-time monitoring and analysis of the displacement of the upper, middle, and lower sections of the buckstay and calculates the buckstay deflection. Experimental results demonstrate that the deviation between the automated measurements and manual measurements of the upper and middle sections of the buckstay is less than 2 mm, while the deviation for the lower section is less than 1 mm, confirming the system's high precision and stability. Additionally, the system completes curvature measurements for the entire coke oven within 1 h with only one operator, achieving an efficiency improvement of over 87.5% compared to manual methods. It also reduces manual intervention and hazardous operations. Therefore, it can be concluded that the proposed intelligent measurement system is highly suitable for monitoring buckstay deflection during coke oven production, effectively preventing risks associated with buckstay deformation.
