Abstract: Traditional manual disassembly and assembly of continuous casting slide gate cylinders require direct exposure to harsh working environments such as high temperature, high noise, and diffuse dust, featuring high labor intensity and high safety risks. The developed automatic disassembly and assembly technology for continuous casting slide gate cylinders takes the upper computer as the control core, with PLC responsible for bottom-level data collection and logic control. High-performance industrial robots are selected as actuators, supplemented by a 3D vision inspection system that detects distance characteristic values to adjust the cylinder piston stroke to match installation requirements and provides real-time target poses to the robot, enabling fully automated operations throughout the entire process of slide gate cylinder positioning, disassembly, and installation. Verified by on-site tests, this technology has successfully enabled robots to completely replace manual disassembly and assembly operations by robots. All performance indicators meet or exceed the requirements of production processes, significantly improving production efficiency and safety, and providing strong support for the intelligent upgrading of continuous casting production.
