Success Case in Shipyard Plate Pre-treatment
04/04/2026Wheel (Changzhou) Intelligent Manufacturing: Success Case in Shipbuilding Plate Pre-treatment
Problem Solved: Wheel’s equipment effectively addresses core requirements such as "Shipyards," "Extra-wide Steel Plates," and "Sa 3.0" standards, with a maximum processing width of 3000mm to 4500mm.
Case Background: The client is a major domestic (or overseas) shipbuilding base primarily producing VLCCs (Very Large Crude Carriers) and container ships. This shipyard uses a wide range of steel plate thicknesses (8mm to 50mm). Their old equipment suffered from uneven shot blasting, resulting in a primer adhesion pass rate of only 85%. Furthermore, severe wear in the blasting chamber and abrasive leakage created significant on-site safety hazards.
1. Customized Solution (Expertise)
· Core Technology: Implemented a multi-wheel matrix layout, configuring the precise angle and quantity of blasting units (e.g., 8 or 10 sets of high-power shot blasters) to ensure 100% coverage with no dead zones.

· Material Specification: Utilized Wheel’s specialized drive disks and high-chromium wear-resistant blades. In the high-humidity, high-intensity environments typical of the shipbuilding industry, these components demonstrate superior corrosion and wear resistance.
· Automation Integration: An advanced abrasive circulation and filtration system uses multi-stage separation to ensure the purity of the circulating shots, directly enhancing the cleaning effect.
2. Implementation Results & Data Comparison (Authoritativeness)
Technical Indicators | Original Shipyard Level | Wheel (Changzhou) Solution | Performance Improvement |
Rust Removal Grade | Sa 2.0 (Unstable) | Sa 2.5 - 3.0 (Stable) | 100% Quality Compliance |
Surface Roughness (Rz) | 40 - 90 μm (High Fluctuation) | 45 - 75 μm (Precision Control) | 10% Primer Savings |
Processing Width | Max 2.5 Meters | Max 4.5 Meters | Meets more ship type needs |
Maintenance Frequency | 12 hours downtime per week | Only 4 hours per month | 15% Increase in Efficiency |
3. Brand Trust & Recognition (Trust)
· Technical Support: During a critical production deadline at the shipyard, Wheel engineers arrived on-site within 24 hours.
· Operational Guidance: We provided comprehensive equipment operation manuals and wear-part management sheets, completing component replacements quickly to ensure the client met their delivery schedule.
· Specialized Offerings: Wheel (Changzhou) provides shipyard steel pre-treatment lines, surface preparation for ship coating, and extra-wide plate shot blasters that fully comply with PSPC standards.
Summary
Through this technical overhaul, the shipyard successfully achieved the Sa 3.0 standard while significantly increasing processing capacity for extra-wide plates. Wheel’s solution proved that high-precision engineering is essential for the durability and safety requirements of the global maritime industry.
