15m x 1.8m x 3m LPG-Fired Environmentally Friendly Hot-Dip Galvanizing Line | 510-Ton Zinc Kettle | WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD.

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. presents the advanced 15-Meter Liquefied Gas Linear Environmentally Friendly Hot-Dip Galvanizing Production Line, engineered for high-volume steel component galvanizing. Designed to accommodate a massive 510-ton zinc kettle with internal dimensions of 15m (L) x 1.8m (W) x 3m (H), this system delivers a maximum hourly capacity of 20 tons/hour, making it an ideal solution for large-scale industrial operations

This production line integrates cutting-edge technology to ensure superior coating quality and operational efficiency. The galvanizing furnace features a high-speed pulse combustion system with dual main gas line control for uninterrupted operation, utilizing LPG with a calorific value of 8400–8600 kcal/m³. The system achieves precise temperature control between 438–450°C with a 3-segment PIC controller and large-screen display, ensuring uniform zinc coating and reduced zinc consumption.

Environmental protection is a core focus of this design. The line includes a comprehensive acid mist containment chamber, a dual-sided zinc fume collection system, and a 185kW bag filter with deodorization spray treatment. The pickling section features seven sealed PP tanks (15x1.8x3m) with an enclosed acid mist treatment room, ensuring negative pressure operation and zero acid vapor escape.

A standout feature is the patented waste heat utilization system, which significantly reduces energy costs. Flue gas waste heat is recovered to:

• Preheat combustion air to 50–150°C, saving approximately 3m³ of gas per ton of galvanized parts.

• Heat the fluxing solution to 50–70°C via a stainless steel heat exchanger.

• Dry sludge from the filter press, reducing moisture content from 80% to 10% and cutting disposal costs.

The line is equipped with fully automated material handling, including 5T+5T roof-mounted hoists with wireless remote control for pickling operations, rail transfer cars, and hydraulic lifting stations. The PLC-controlled system ensures precise immersion timing, preventing over-galvanizing and reducing costs.

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. provides a complete turnkey solution, from pre-treatment through post-treatment, including waste heat exchangers, cooling towers, and automatic iron removal equipment for flux solutions. With a total power consumption of approximately 480kW and a supply scope encompassing 12 PP tanks, enclosed acid rooms, and dual combustion systems, this production line represents the pinnacle of modern galvanizing technology.
