Customized ISO9001 7.0×1.2×2.2 m Zinc Tank for a 20,000 Ton/Year Hot Dip Galvanizing Line
This project delivers a complete customized hot dip galvanizing line centered on a 7.0 × 1.2 × 2.2 m zinc tank, engineered for a 20,000 ton per year production capacity. The line is installed in an 81 × 15.9 m workshop, arranged in a ring layout, and heated by a furnace oil burning system. Every component is built to ISO9001 quality standards and sized around the customer's actual workpiece mix.

Key Technologies
- High speed pulse heating — uniform heating, high thermal efficiency, and a significantly extended service life of the zinc tank.
- Intelligent heating control system — whole-process real-time data monitoring with fault diagnosis and alarm functions.
- Acid concentration testing equipment — the state of the acid can be monitored at any time so the production rhythm can be adjusted precisely.
- Closed industrial waste gas collection — centralized treatment that meets discharge standards with no overflow.
- New process without water washing — reduces both investment and operating costs.
- Zinc dust collector (option) — high dust removal efficiency, easy maintenance, compact footprint.
Tank Dimensions of the Main Production Line
The equipment mainly consists of a degreasing tank, acid pickling tanks, flux tank, galvanizing tank, water cooling tank, passivation tank, the galvanizing tank heating and control system, a ring type crane, an acid fume collection and treatment system, an optional fixed zinc smoke collecting and treatment unit, a flux de-ironing device, a flux heating system using flue waste heat, and a water cooling system.

Electricity, Water and Gas Requirements
- Power: maximum power of electrical equipment 230 kW.
- Water consumption: 0.01 m³ per ton, supply pressure not less than 0.2 MPa.
- Water quality: pH 6.5–8 tap water, river water or well water is acceptable.
- Compressed air: 0.5 MPa pressure with 3 m³/min supply.
Design Principles
Every design decision on this line follows four principles: energy saving, environmental protection, technology leadership and reliable quality at a cost-effective price. The result is a galvanizing plant that runs efficiently for 20,000 tons per year, keeps emissions inside the legal envelope, and protects the zinc tank through stable, precisely controlled thermal conditions.
