TOP: Boost Shipyard & Steel Plant Productivity XKMT Automatic Steel Anti-Corrosion Line
2026-06-22
Industries such as shipbuilding, bridge construction, large steel structure engineering and heavy equipment manufacturing impose extremely high standards for steel surface treatment. The pretreatment quality of steel plates and profiles directly determines the anti-corrosion performance, service life and overall safety of structural components. Thorough removal of mill scale and rust, together with professional protective coating before welding and assembly, serves as an essential and quality-determining procedure in heavy industrial production.
For years, most heavy-duty manufacturing facilities have depended on traditional manual segmented workflows to finish steel descaling, preheating, painting and drying. This conventional method comes with notable disadvantages. It consumes massive labor resources and restricts overall production throughput, while easily leading to incomplete rust removal, uneven paint thickness and inconsistent processing standards. These common flaws frequently result in paint peeling and secondary rusting, bringing higher rework rates and long-term maintenance burdens. Outdated manual operation modes are no longer suitable for modern large-scale, standardized production, and have become a key bottleneck limiting factory productivity and quality improvement.
To tackle these long-standing industry challenges, XKMT leverages decades of professional experience in heavy-duty surface treatment and has independently developed a fully automatic anti-corrosion pretreatment production line. This advanced equipment integrates four core procedures — preheating, deep descaling, intelligent painting and constant-temperature drying — into one unified continuous automated system. It fully replaces inefficient manual operation modes and perfectly solves mainstream industry problems, including low pretreatment efficiency, unstable finishing quality and unnecessary energy consumption.
The product’s core competitiveness is reflected in seamless full-process automation. Fitted with a smart roller conveying system, the entire production line requires zero manual handling of workpieces. Steel materials move at a stable, constant speed through the preheating chamber, multi-wheel through-type Shot Blasting Machine, intelligent painting booth and constant-temperature drying oven. All working procedures are highly coordinated with synchronized operating rhythms, eliminating equipment idle time, process waiting and productivity loss caused by manual transfer. This greatly boosts overall production efficiency and long-term operational stability.
Equipped with a professional intelligent energy-saving painting system, the production line adopts high-precision photoelectric sensors to automatically identify workpiece shapes and profiles. It intelligently generates optimal spraying trajectories and precisely controls spray gun switching. This targeted spraying approach delivers uniform, smooth and high-quality coating finishes. Meanwhile, it effectively reduces paint overspray and material waste, cutting down consumable investment and lowering comprehensive operational costs for manufacturers.
The equipment provides reliable, high-standard descaling performance that meets international industrial specifications. Configured with XKMT self-developed heavy-duty high-efficiency blast wheels and a professional closed-loop air separation system, it thoroughly clears heavy rolling mill scale and stubborn rust on steel surfaces, consistently reaching Sa2.5 and Sa3.0 premium surface treatment standards. The treated steel forms a uniform and reasonable rough surface, which greatly improves paint adhesion. It fundamentally avoids common issues such as paint peeling and recurring rust, effectively prolonging the service life of various steel structure components.
Aligned with Industry 4.0 intelligent manufacturing development trends, XKMT offers reliable full-line customized solutions. According to customers’ actual factory space, site layout, workpiece specifications and production capacity demands, we customize every key parameter, including production line layout, roller conveying speed, blast wheel power, ventilation and dust removal systems, and painting configurations. The highly adaptable tailored design fits diverse complex heavy-duty working conditions, helping steel plants and shipyards achieve standardized, intelligent and high-efficiency upgrading of steel pretreatment processes.
