High-Efficiency LPG Gas-Fired Hot Dip Galvanizing Furnace Line - 35 Ton Capacity, Energy-Saving & Automated

High-Efficiency LPG Gas-Fired Hot Dip Galvanizing Furnace Line - 35 Ton Capacity, Energy-Saving & Automated

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. presents its state-of-the-art LPG Gas-Fired Hot Dip Galvanizing Production Line, engineered for efficiency, durability, and environmental compliance. Designed with an effective zinc kettle size of (L)6m × (W)1.0m × (H)1.0m and a 35-ton zinc capacity, this system delivers a maximum hourly output of 2 tons. It integrates innovative energy-saving technologies, such as flue gas waste heat recovery, which preheats combustion air to 100–200°C, reducing gas consumption by approximately 2 cubic meters per ton of processed workpieces. The line also features a fully enclosed acid treatment room, mobile zinc fume extraction hoods, and automated PLC-based controls to minimize operational costs and environmental impact.

Key components include a high-speed pulse combustion furnace for uniform heating, an intelligent acid mist management system, and a sludge drying unit that cuts waste volume by up to 70%. The electrical and automation architecture employs Siemens PLCs (S7-1500/1200), PROFINET communication, and WinCC HMI interfaces for seamless monitoring and control. With a focus on reducing carbon emissions and optimizing resource use, this galvanizing line is ideal for medium to large-scale operations seeking reliable, low-maintenance, and eco-friendly production solutions.

The line’s design emphasizes sustainability through multiple patented waste heat recovery modules, including a combustion air preheater and an integrated sludge drying tank. These features not only lower fuel and electricity expenses but also help factories meet stringent environmental regulations. The enclosed acid pickling room with PP/PPH or fiberglass lining, coupled with a dual-tower acid mist neutralization system, ensures a safer workplace and reduces emissions. For added flexibility, the system supports optional add-ons such as automated galvanizing machines for profiles, guardrails, or wire products.

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. ensures every galvanizing line is built with robust materials—like 60mm thick zinc kettle walls and 310S stainless steel protective plates—and backed by comprehensive automation, from sequence control to real-time video surveillance. Ideal for galvanizing steel structures, pipes, guardrails, and fasteners, this production line combines high throughput with remarkable energy savings, making it a smart long-term investment for modern metal finishing plants.
