Key Features - Intelligent S-Roller Control System: Combines tension-type and speed-type regulation for seamless strip handling before and after galvanizing. - High-Precision Tension Management: Utilizes load cells and feedback loops to maintain exact tension levels during critical processing stages. - Constant-Speed Conveyance: Ensures uniform movement through non-critical zones via motorized roller drives set to fixed rotational speeds. - Surface Pretreatment Integration: Removes oil, scale, and contaminants to promote strong adhesion of the zinc layer. - Continuous Operation Capability: Supports uninterrupted flow from coil entry to finished galvanized coil exit—ideal for high-volume production environments. Detailed Description This advanced
hot dip galvanizing line employs a dual-control strategy for its S-rollers, ensuring adaptability across different operational phases. In areas where precise tension must be maintained—such as before immersion in the molten zinc bath—the system deploys tension-type control. A calibrated weighing sensor continuously monitors the strip’s tension, allowing real-time adjustments to roller position or pressure to prevent slippage, wrinkling, or breakage. Conversely, in transport sections where steady velocity is more critical than tension, speed-type control takes over. Here, servo motors regulate roller rotation at predetermined speeds, enabling smooth and efficient material movement throughout the entire galvanizing sequence. The core of the process lies in the hot-dip galvanizing method itself—a proven technique that immerses cleaned steel coils into a bath of molten zinc at approximately 450°C (842°F). This results in a metallurgically bonded zinc-iron alloy layer that offers exceptional resistance to corrosion, making the final product ideal for outdoor applications. To prepare the steel surface, the system includes chemical cleaning units, degreasing stations, and annealing furnaces that eliminate impurities and restore the metal’s reactivity, ensuring maximum adherence of the zinc coating. In addition to structural integrity, the production line incorporates safety features such as temperature monitoring, emergency braking systems, and automated lubrication for reduced downtime. Its modular design allows for customization based on coil width, thickness, and zinc coating weight requirements, accommodating both thin gauge and heavy-duty steel products. Use Cases Ideal for manufacturers producing galvanized steel sheets for roofing, fencing, automotive body panels, electrical enclosures, and industrial containers, this line supports both standard and custom specifications. It is particularly well-suited for facilities aiming to upgrade from batch processes to continuous galvanizing lines, offering improved throughput, energy efficiency, and consistency in finish quality.
