Core Technical Advantages
Equipped with PLC intelligent control system and online detection equipment, it real-time monitors key parameters such as coating thickness, temperature and speed. The fluctuation of zinc coating thickness can be controlled within ±2μm, and the defect detection rate reaches 99.9%, ensuring product consistency.
The maximum operating speed of a single production line can reach 150m/min, with an annual processing capacity of up to 150,000 tons. Compared with traditional intermittent production, the efficiency is increased by 3-5 times, which is suitable for large-scale and mass production needs.
Equipped with zinc fume recovery and purification system, acid mist absorption device and integrated wastewater treatment equipment, the emission of waste gas and wastewater is far lower than the national standard; adopting high-efficiency annealing technology, the energy consumption is reduced by 15-20% compared with traditional production lines, realizing green production.
It can process various cold-rolled/hot-rolled steel strips with thickness of 0.15-3.0mm and width of 900-1800mm, and supports customization of different zinc coating thicknesses (80-275g/m²), meeting the coating requirements of products in construction, home appliances, automotive and other fields.
Core components are made of high-temperature and corrosion-resistant alloy materials, and the service life of the zinc pot is as long as 8-10 years; modular design facilitates installation and maintenance, greatly shortens downtime for maintenance, and improves equipment utilization rate.
