The hot-dip galvanizing production line is a specialized equipment used for the surface treatment of steel materials. With an annual output of 200,000 tons, the production line uses a continuous operation mode and has a high degree of automation. The unit is composed of an uncoiling machine, a pre-treatment device, a drying furnace, a galvanizing furnace, and a cooling device. The pre-treatment device includes an alkaline cleaning tank, a pickling tank, and a washing tank. The drying furnace is composed of a furnace body, a heating system, and an exhaust system. The galvanizing furnace is composed of a furnace body, a zinc pot, and a heating system.

During operation, the steel material is first placed on the unwinding machine for uncoiling, and then enters the pre-treatment device for surface cleaning and rust removal. Next, the material is dried in the drying furnace, and then enters the galvanizing furnace. In the furnace, the steel material is immersed in the zinc pot and then taken out for cooling. Finally, the coated steel plate is coiled by the coiling machine. The production line has a stable and reliable operation, high degree of automation, and excellent product quality.
