Our company has maintained close cooperation since 2000 with Hangzhou Chuangyu Metal Products Technology Co., Ltd., Hangzhou Chuangli Technology Service Co., Ltd., Maccaferri (Hangzhou) Metal Materials Technology Co., Ltd. and other enterprises in the field of hot-dip galvanizing alloy technology for steel wires. We have independently developed the redox-based hot-dip galvanizing alloy technology for steel wires and formed a complete set of technical solutions. The core technologies have been granted multiple invention and utility model patents. This technology has been widely applied in numerous steel wire hot-dip galvanizing enterprises, delivering remarkable economic and social benefits with broad application prospects.

Main Technological Process of the Production Line for Redox-based Hot-dip Galvanizing Alloy Technology for Steel Wires

1. Wire pay-off from I-wheel spools

2. Hot water washing / Alkaline cleaning

3. Ultrasonic cleaning

4. Redox annealing

5. Hot-dip aluminum-zinc galvanizing

6. Wire take-up

Advantages Over Conventional Production Lines

1. Eco-friendly with zero pollutionAdopting redox annealing technology eliminates the traditional pickling, rinsing and fluxing processes, realizing pickling-free hot-dip aluminum-zinc galvanizing for steel wires.

2. Nitrogen wiping technology for superior coating qualityThis technology optimizes working conditions and reduces air pollution while improving the quality of galvanized coatings.

3. Proprietary single-coating processThe conventional double-coating procedure is removed, which simplifies the process flow, cuts capital investment and lowers production costs.

4. High-capacity production & higher efficiencyEquipped with large-capacity I-wheel pay-off and inverted wire take-up systems to support large-batch production and boost overall productivity.

5. Higher operational availability of the production lineUltrasonic cleaning ensures excellent coating quality, prevents furnace tube blockage caused by surface contaminants on steel wires, extends the service life of furnace tubes, reduces downtime for maintenance and greatly improves line operational rate.
