Travel Chassis: Adopts a crawler-type design with a hydraulic drive system. It enables flexible adjustment of the equipment’s position, adapts to the complex site environment of steel plants, and achieves alignment operations for ladles of different specifications.
Working Arm System: Features a multi-section telescopic hydraulic arm equipped with a 360° rotating joint, allowing precise coverage of all areas of the ladle lining. The end of the arm is fitted with a breaker hammer, hydraulic shear, or milling head to meet the removal needs of different refractory materials (e.g., magnesia-carbon bricks, high-alumina bricks).
Hydraulic Power Unit: Provides high-strength crushing power. It controls the operating force through oil pressure adjustment to avoid damage to the ladle shell while ensuring continuous operation.
The equipment moves to the side of the ladle via the travel chassis, and the angle of the working arm is adjusted to align with the ladle opening.
After the hydraulic power unit is activated, the crushing device at the end of the arm applies high-frequency impact or shearing force to the invalidated lining, breaking the refractory material into small pieces.
The crushed residue is discharged through the slag outlet at the bottom of the ladle or collected by an auxiliary slag cleaning device.
Throughout the operation, the control system real-time monitors the temperature and wall thickness of the ladle shell to prevent shell deformation caused by over-crushing, ensuring precise and safe removal.
High-Efficiency Operation: Compared with manual removal, mechanized operation improves efficiency by 5–8 times. The removal time for a single ladle is reduced from the traditional 12–24 hours to 3–6 hours, significantly shortening the production waiting time for steel plants.
Safety and Reliability: Operators work via remote control or an operation console, keeping away from high temperatures, dust, and collapse risks—completely eliminating the safety hazards of manual removal. Additionally, the equipment is equipped with safety devices such as overload protection and emergency braking to ensure stable operation throughout the process.
Precision Protection: Through intelligent sensing and power adjustment technology, the crushing force can be precisely controlled to remove only the invalidated lining layer without damaging the ladle shell. This extends the ladle’s service life and reduces equipment maintenance costs.
Environmental Protection and Energy Efficiency: A dust collection device is installed during operation to reduce dust pollution, complying with environmental requirements. The hydraulic drive system features low energy consumption and low noise, offering greater green advantages compared to traditional methods such as blasting removal.
Strong Versatility: By replacing the working end and adjusting operating parameters, it can adapt to the lining removal of containers of different specifications (50–300 tons), such as ladles, hot metal ladles, and tundishes, meeting the multi-scenario O&M needs of steel plants.
Production Efficiency: Shortens the ladle maintenance cycle, ensures continuous production in steel plants, and helps increase production capacity.
Cost Control: Reduces labor input and equipment wear, lowers O&M costs, and improves the economic benefits of enterprises.
Safety and Environmental Protection: Practices the concept of "safety first, green development" and promotes safety production and environmental upgrading in the iron and steel industry.
Industry Upgrading: As an important embodiment of the intelligence of metallurgical equipment, its technological development drives the iron and steel industry toward high efficiency, intelligence, and green development, supporting the high-quality development of the industry.
