Abstract

This invention discloses a refractory spraying system and method for tundishes. The system includes guide rail modules laid along three tundish workstations, a work machinery unit equipped with a six-degree-of-freedom robotic arm, a lifting drive mechanism, modular work components integrating electrical and pneumatic connection modules, a quick-change material box, and a central control system. The six-degree-of-freedom robotic arm's range of motion can cover the entire area inside the tundish. The work method adopts a three-station continuous operation mode, precisely matching the process time of refractory spraying and drying. It can also switch between high-speed and low-speed spraying modes to adapt to different tundish wall temperatures and is equipped with a standardized construction process. This invention achieves no idle time for the work machinery, improves construction efficiency and spraying quality, eliminates blind spots in construction operations, has a high degree of automation throughout the process, low equipment maintenance costs, strong system versatility, and can adapt to the needs of industrialized batch construction.
