Hot dip galvanising equipment (hot dip galvanizing equipment) is used to form a dense zinc-iron alloy layer by immersing steel in a molten zinc solution at 450°C, with a corrosion protection life of more than 50 years. The core components include:
Galvanising furnace (hot dip galvanizing furnace): gas or electric heating, equipped with a zinc circulation system;
Pre-treatment line: pickling and soaking with auxiliary plating agent to ensure the surface cleanliness of the substrate;
Automated control system: PLC regulates the zinc dipping time and lifting speed to guarantee the uniformity of the coating.
For example, Leimeng Equip's full-automatic galvanising line (automatic hot dip galvanizing plant) can handle 5 tonnes of steel components per hour, which is suitable for large-scale projects such as transmission towers and highway guardrails.
For laboratory or small-scale production needs, the small galvanizing machine features a compact design with a portable zinc pot and safety guards. Users can handle small workpieces such as bolts and hardware fittings with a single treatment capacity of 50-100kg and 40% lower energy consumption, making it suitable for start-ups or customised production.
Regular maintenance is the key to prolonging equipment life:
Zinc slag cleaning: weekly removal of impurities from the bottom of the zinc pot to avoid rough plating;
Burner calibration: monthly testing of gas thermal efficiency to reduce energy wastage;
Spare parts inventory management: stock up on wear parts such as graphite bearings and thermocouples to reduce downtime.
