AI Technical Summary

Technical Problem

Traditional blowing furnace spray gun control systems struggle to accurately acquire rotation angle, angular velocity, and heat distribution in real time under high temperature and strong corrosive environments, leading to deviations in motion trajectory. Furthermore, the lack of effective deviation identification and compensation mechanisms impacts production efficiency and product quality, resulting in short equipment reliability and lifespan.

Method used

The spray gun attitude sensing module acquires the spray gun status through multi-sensor fusion, constructs an ideal rotation trajectory model and identifies deviations, and combines it with the compensation control module to generate rotation speed and position translation compensation commands, forming a closed-loop control mechanism, and is equipped with a high-temperature protection structure.

Benefits of technology

This improved the precision and reliability of spray gun motion control, extended equipment life, increased production efficiency and product quality, and reduced maintenance costs.

Abstract

The invention provides an intelligent regulating and controlling system for spray guns of a multi-gun top-blowing converting furnace. The rotating angle, the angular speed, the posture and the heat distribution of the spray guns are obtained in real time through multiple sensors; comparing an ideal trajectory model with an actual trajectory, and identifying a high-dimensional deviation; generating a rotation speed adjustment and space translation compensation instruction according to the deviation; closed-loop feedback real-time correction is carried out, and perception-decision-execution-feedback control is realized; the system comprises a ceramic heat insulation structure, a water cooling structure, a sealing structure and a high-temperature protection structure of a metal shell. Motion deviation of the spray guns can be reduced, blowing efficiency and stability are improved, and production efficiency and product quality of the multi-gun top-blowing converting furnace are improved.
