Natural Gas Fired Hot Dip Galvanizing Furnace Line with 35 Ton Capacity and 6x1.0x1.0m Zinc Pot in Energy-Saving Design

Natural Gas Fired Hot Dip Galvanizing Furnace Line – 6x1.0x1.0m Zinc Pot, 35 Ton Capacity, Energy-Saving Design

WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. offers an advanced LPG/Natural Gas Fired Hot Dip Galvanizing Furnace Line engineered for high productivity, energy savings, and environmental compliance. Designed with an effective zinc pot size of (L)6.0m × (W)1.0m × (H)1.0m and a 35-ton zinc capacity, this system delivers a maximum hourly output of 2 tons. The furnace utilizes clean LPG or natural gas with a calorific value of 8400–8600×4.18 kJ/m³ and operates under micro-positive pressure for stable and efficient heating. Key innovations include a patented flue-gas waste-heat recovery system that preheats combustion air to 50–150°C, saving approximately 2–3 cubic meters of gas per ton of processed workpieces. An optional sludge-drying unit further reduces waste volume by up to 70%, lowering disposal costs and enhancing environmental performance.

The galvanizing line integrates a high-speed pulse combustion system with four TJ075 burners, dual gas supply controls for redundancy, and UV flame detection for safety. Temperature is precisely regulated via a three-stage PLC system, maintaining zinc bath temperatures between 438–450°C. The electrical drive system employs frequency converters for induced-draft and blower fans, reducing power consumption to about 20 kW during normal operation. With a fully enclosed acid treatment zone, efficient fume extraction, and automated material handling, the line ensures a safer workplace and meets stringent emission standards.

Technical Parameters Table:

WUXI WONDERY’s furnace is built with durable components, including a 60mm-thick zinc pot, 310S stainless steel protective plates, ceramic fiber insulation modules (withstanding over 1000°C), and a robust steel-structure furnace body. The line is supplied with complete combustion system components—such as Italian gas filters, German KROM ratio valves, and American Eclipse burners—ensuring reliability and long service life. Optional add-ons include waste-heat hot air systems and sludge drying boxes, which can be tailored to customer needs.

Ideal for galvanizing structural steel, guardrails, pipes, and fasteners, this production line combines high throughput with significant operating cost savings. By integrating intelligent temperature control, energy recovery, and low-emission design, WUXI WONDERY INDUSTRY EQUIPMENT CO., LTD. provides a future-proof solution for metal finishing plants aiming to enhance efficiency while reducing their carbon footprint.
