Aluminum galvanizing line
The aluminum galvanizing line is a set of equipments that plating a layer of zinc or aluminum alloy on the strip while in high temperature. The production line was composed of uncoiler, welder, storage tank, degreasing section equipments, continuous annealing furnace, zinc pot, air knife, skin pass, tension leveler, oiler, shear, recoiler and other equipments.

Equipment Characteristics:
1. Equipped with steel chemical cleaning or high efficiency electrolytic cleaning section, optional cleaning mode combining horizontal spray with vertical immersion spray, and unique electrolytic cleaning and ejecting mixing technology, which achieve higher current efficiency and avoid secondary oil pollution of plate out of slot , liquid surface directive overflow to ensure that the electrolyte surface rarely burst air bubble, and high safety of system service.
2. The combination of non-oxidizing (NOF) and radiant tube heating (RTH) has the advantages of fast heating speed, high thermal efficiency, more finer double cross-limiting air-fuel ratio control method is adopted , special refractory material is selected, which can significantly improve the insulation effect and service life of the high temperature zone.
3. After annealing, the strip cooling adopts protective gas cycling spray cooling way with variable frequency speed control. The use of high-pressure high-speed jet, strip cooling is quick and uniform, which can accurately control the process temperature of strip entering into zinc pot.
4. Straightening machine and finishing machine can effectively improve the finished product surface and shape quality, and improve product coating and cold crushing mechanical properties.
5. Adopt flue gas waste heat recovery technology, recover low temperature flue gas waste heat through the flue gas - water heat exchange or waste heat steam boiler, supply the recovered waste heat to heat liquid cleaning section , thus to improve the utilization of heat and reduce product energy consumption.
6. The use of jet-type ceramic induction heating zinc pot, with fast heating, uniform temperature and alloy composition, long service life and less slag and other advantages. The furnace nose is equipped with wet nitrogen and circulating zinc pump device inside, which can significantly improve the strip surface accuracy, especially suitable for coated substrate quality requirements of home appliances .
7. The coating thickness measuring instrument can be used to monitor the actual thickness of the coating in real time and guide the precise adjustment of the air knife.
8. The use of fingerprint-resistant coating machine with fast switching device can effectively optimize the equipment layout of process section, reduce the investment in plant construction, and obtain accurate organic or composite coating on the strip surface.
9. Control system adopts vector frequency control, CPC and EPC correction, field bus control technologies, with good man-machine interface and stable and reliable equipment service.
