Product Overview
- Coil Coating Lines Product Line from HiTo Engineering includes hot-dip (aluminum) galvanizing lines and continuous galvanizing/galvalume lines designed as complete production systems (uncoiler, welder, furnace, zinc pot, air knife, skin pass, leveler, oiler, shear, recoiler, etc.).
- Typical processed substrate: cold‑rolled low carbon steel (SPCC/SPCD, JIS G 3141). Thickness range 0.12–2.5 mm, width 700–1550 mm. Coatings: GI / GA / GF at 30–300 g/m2. Product grades: CQ, DQ, G550 (JIS G 3302).
- Line performance: entry/exit up to 260 mpm, processing up to 200 mpm; annual capacity typically 60,000–300,000 MT. Electrical load range cited ~2,500–4,500 kW. Fully configurable to customer requirements.
Product Features
- Flexible cleaning options: chemical and high-efficiency electrolytic cleaning, combined horizontal spray + vertical immersion, and innovations to avoid secondary oil contamination.
- Advanced heating and annealing: non-oxidizing (NOF) + radiant tube heating (RTH) for fast, efficient heating with refined air‑fuel control and durable refractory materials.
- Precise cooling and coating control: protective gas cycling spray cooling with VFD control, high-pressure jet cooling, real‑time coating-thickness measurement, and air-knife adjustment guidance.
- Modern zinc pot and coating modules: ceramic induction heating zinc pot, wet nitrogen furnace nose, circulating zinc pump; fingerprint-resistant/coating machines with fast switching.
- Automation & safety: vector frequency drives, CPC/EPC correction, fieldbus control, user-friendly HMI/software (English), and strong quality-control practices.
Product Value
- Tailor-made engineering delivers solutions aligned to customers’ production goals, budgets and product specifications.
- Improves end-product surface quality, coating uniformity and mechanical properties, supporting higher market competitiveness.
- Increases production efficiency and throughput while reducing operating cost through heat recovery and energy‑saving measures.
- Offers full specialist support and ongoing service, reducing commissioning risk and long-term downtime.
Product Advantages
- World-class technology at competitive pricing combined with strong after-sales and specialist backup.
- High process control and repeatability (real-time thickness monitoring, advanced control systems) for consistent product quality.
- Energy and cost savings via flue gas waste-heat recovery and efficient heating/cooling systems.
- Equipment design reduces slag, improves uniformity and surface accuracy (suitable for appliance-grade substrates).
- Customizable configuration, English language software/HMI, and robust quality-control and manufacturing support.
Application Scenarios
- Production of galvanized/galvalume coil products for construction (roofing, cladding), appliances, building materials and general steel processing.
- Steel service centers and mills upgrading or installing continuous galvanizing/galvalume or hot‑dip aluminum/zinc coating lines.
- Manufacturers requiring high‑quality coated substrates with strict surface/appearance standards (e.g., home appliances, architectural panels).
- Projects where energy efficiency, waste‑heat recovery and precise coating control are priorities, or where turnkey, configurable solutions and long-term technical support are required.
