QXY Steel Plate Pretreatment Line for Integrated Smart Production
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.
Product Introduction
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.

QXY Steel Plate Pretreatment Line for Integrated Smart Production: FAQ'S
What processes are included in the QXY pretreatment line?
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.
Can the painting thickness be controlled?
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.
What is the typical maintenance cycle?
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.
How does the system handle different plate sizes?
Integrated sensors automatically detect the width and position of the plates, adjusting the blast wheels and spray guns for optimal efficiency without manual reconfiguration.
