The QXY Steel Plate Pretreatment Line is a premium, fully automated solution designed for the comprehensive surface treatment of large-scale steel plates and profiles. Engineered for integrated smart production, it seamlessly combines preheating, shot blasting, automatic painting, and drying in a single continuous workflow.
Specifically suited for shipbuilding, bridge construction, and offshore engineering, this system delivers a superior Sa 2.5 cleanliness level and uniform coating thickness while maintaining strict 10mg/m³ dust emission standards, ensuring maximum productivity and environmental compliance.
Our QXY Series Steel Plate Pretreatment Line represents the pinnacle of surface preparation technology. Unlike standalone blasting machines, this integrated line eliminates the need for manual transport between cleaning and coating stages. The process begins with high-efficiency preheating to remove moisture, followed by aggressive descaling via high-performance turbines to reach ISO 8501-1 standards.
Centrally managed by a Siemens PLC system, the line features precision automatic spray guns and an intelligent drying tunnel that ensures a consistent, high-quality primer coat. Powered by ABB electrical components, the QXY series is designed for 24/7 industrial operations in shipyards and steel service centers, providing a robust foundation for subsequent welding and fabrication.
Integrated Workflow: Combines preheating, blasting, painting, and drying to provide a complete, one-stop surface preparation solution.
Intelligent Control: Centrally managed by Siemens PLC and ABB electrical components, ensuring precise synchronization of the entire line.
Uniform Coating Quality: Features high-precision automatic spray guns and an intelligent drying system for consistent paint thickness.
Smart Energy Saving: Equipped with advanced sensors to detect workpieces, automatically adjusting power and paint consumption for cost efficiency.
Eco-Friendly Standard: High-efficiency pulse-jet filtration system ensures dust emissions stay below 10mg/m³, meeting strict OSHA safety standards.



CLEANING RESULT: Sa 2.5 (High Efficiency)
Witness the power of full-scale automation with the QXY Series. See how raw steel plates are transformed through our integrated preheating, blasting, and coating modules. Experience a streamlined workflow that minimizes manual intervention and maximizes industrial output.
The line typically includes a loading conveyor, preheating oven, shot blasting machine, automatic painting booth, drying tunnel, and unloading system. This integration ensures the steel is cleaned and primed in minutes, preventing flash rust.
Yes. Our intelligent spraying system allows for precise control of paint thickness (typically 15-45 μm), ensuring a uniform finish across all plates and minimizing paint waste.
The shot blasting module uses high-chromium wear-resistant components with a service life exceeding 800 hours. The spraying and drying sections are designed for easy access, ensuring minimal downtime for nozzle cleaning or filter changes.
Integrated sensors automatically detect the width and position of the plates, adjusting the blast wheels and spray guns for optimal efficiency without manual reconfiguration.
